Many facial sunscreens are formulated to reduce oiliness and are often more expensive than body products. “But the higher price doesn’t mean it offers better protection,” says Kimberly Jerdan, a board-certified dermatologist in the US. Here’s her advice on how to choose the right sunscreen for your face. Use a broad spectrum sunscreen When buying any sunscreen, there are two main signs to look for. Make sure the bottle says “broad spectrum”. Also, choose one with at least SPF 30. Choose a sunscreen that says “broad spectrum”. Photo: UChicago Medicine. Broad spectrum means the sunscreen protects the skin from both UVA and UVB rays. UVA rays cause premature aging, wrinkles and dark spots, they penetrate deeply and can damage the skin’s collagen. Meanwhile, UVB rays mainly damage the surface of the skin and cause sunburn. Both UVA and UVB can cause skin cancer. SPF (Sun Protection Factor) is an indicator of how much UVB radiation a sunscreen can filter out. SPF 30 sunscreen blocks 97% of the sun’s UVB rays. A higher SPF provides only a small amount of additional protection and needs to be applied frequently – every two hours. SPF does not measure protection from UVA rays. That’s why you need to make sure your sunscreen has a broad spectrum label to get protection from both. “Higher SPF sunscreens tend to be a bit more expensive. So I’d recommend saving money and just getting into the habit of reapplying every two hours,” says Jerdan. Based on how oily or dry your skin is Finding the right sunscreen can take some trial and error because everyone’s skin is different. If you have oily or acne-prone skin, Joyce Park, a dermatologist in the Bay Area (California, USA) recommends looking for creams labeled “non-comedogenic”. Because they will not clog pores, reducing the risk of acne. Pay attention to choose the right ingredients for your skin type. Photo: Tsww. Park also recommends sunscreens that contain niacinamide. This is a B vitamin that improves the appearance of the skin and reduces sebum production. For dry skin, she recommends looking for moisturizing ingredients like ceramides, hyaluronic acid, or glycerin. Apply sunscreen before makeup Currently, foundation creams also include SPF 30. However, they are often not applied much when wearing makeup. This limits sun protection. “Studies show that people don’t wear enough SPF makeup to get skin protection benefits,” says Dr. Park. So we recommend applying sunscreen to your face before applying makeup. Facial sunscreens are formulated to create different foundations – mist, matte or tinted. So it’s guaranteed to fit into any makeup routine.” Apply sunscreen before applying makeup for full protection. Photo: girlstyle.com Physical sunscreen for sensitive facial skin There are two main types of sunscreens, physical and chemical. Both protect the skin from UV radiation, they just contain different ingredients. It is these different ingredients that will help you choose the right sunscreen for your face. Physical sunscreens are formulated with zinc oxide or titanium dioxide. These are great options for people with sensitive skin because they are hypoallergenic. Another reason mineral sunscreens are ideal for the face is that they reduce the risk of hyperpigmentation and melasma. Jerdan says chemical sunscreens absorb the sun’s rays, so they can warm the face. Therefore, for those who are prone to tanning, it is best to avoid them. “Physical sunscreens can sometimes leave a thick layer of powder on the skin,” says Park. “But over the years, products have improved a lot and that’s no longer the case.” People with sensitive skin should use physical sunscreen. Photo: NBC. Chemical sunscreen Chemical sunscreens absorb the sun’s rays instead of reflecting them back. Jerdan advises patients with sensitive skin to “say no to benzones”. Avobenzone and oxybenzone commonly found in chemical sunscreens can cause allergic reactions. However, not all chemical sunscreens are based on these ingredients. The product still works fine if you are not allergic to it. Chemical sunscreen ingredients are also controversial due to a recent study conducted by the US Food and Drug Administration (FDA). Results showed that these compounds were absorbed into the skin and detected in the blood at levels above the FDA recommended threshold. However, this does not mean that chemical sunscreens are unsafe, researchers and dermatologists stress. Chemical sunscreen will still work as long as you’re not allergic to it. Photo: Freepik.

Overexposure to the sun Exposure to ultraviolet rays is harmful to the skin. Exposure to ultraviolet rays is harmful to the skin. Overexposure to UVA and UVB rays accelerates skin aging, accelerating the production of free radicals. These free radicals damage skin cells and prevent their regeneration. UV exposure also causes hyperpigmentation, dehydration, and premature appearance of wrinkles. Exposure to nicotine Nicotine in cigarettes thins blood vessels. This reduces the supply of oxygen and other important nutrients to the skin. Skin lacking oxygen and nutrients tends to dry out and develop wrinkles from a young age. Stress Excessive stress leads to an increase in hormones such as adrenaline and cortisol in the blood. These hormones deplete the skin of important nutrients and also prevent the regeneration of connective tissue components such as collagen and elastin, which give the skin its elasticity and vitality. Excessive stress leads to thin skin and the development of wrinkles. Street Blood sugar will bind to collagen in the skin. This amount of collagen will be easily broken down and cannot heal on its own. Damaged collagen leads to the development of wrinkles. A low glycemic index diet (rich in protein and fiber) helps to heal damaged collagen and restore skin. Sleepless A good 7-9 hours of sleep is crucial for the skin to be able to recover from damage caused by exposure to environmental toxins, UV rays and other aggressors during the day. Lack of sleep manifests in dark circles around the eyes, dull skin and uneven skin tone. On the contrary, a good night’s sleep helps the skin recover and slows down the aging process. Excessive drinking Excessive alcohol consumption can lead to dilation of blood vessels in the skin. This causes the face to become red and blotchy. In addition, drinking too much alcohol also leads to deficiency of important nutrients in the body. This deficiency can cause premature aging of the skin and the appearance of wrinkles. Banana and honey smoothie Drinking honey banana smoothie before bed helps you maintain the health of your skin. Resources: 1 banana 2 tablespoons honey 250ml fresh milk 1 bit of shaved ice Cups and spoons Banana peeled and then put in a blender puree with honey, fresh milk, shaved ice. After the mixture is ready, pour it into a cup and enjoy. Uses: Natural ingredients in bananas, sweet potatoes, honey, milk… are rich in vitamins and essential minerals. Therefore, persistently applying 1 of the 3 above formulas once a day in the evenings before going to bed will contribute to a healthy body, effective skin beauty support at home. At the same time, you can combine banana mask 3 times a week which is also very good. The method is quite simple, first of all, the bananas are pureed and then mixed with 2 tablespoons of honey + 1 teaspoon of fresh lemon juice. Use the mixture to gently massage your face after cleansing with warm water. Leave for about 30 minutes, after the mixture has dried naturally, wash it again with water. Finally, apply a thin layer of moisturizer to finish the beauty process.

Applying too little sunscreen leads to a lower SPF that prevents the skin from receiving optimal protection from UV rays. As recommended, the amount of sunscreen the size of the palm is enough for the body. As for the face, you should apply a dime-sized amount of sunscreen. Don’t reapply sunscreen often To protect your skin, reapply sunscreen every 2-3 hours. (Illustration) Sunscreen, whether applied or sprayed, degrades after 2 hours of use in the sun. If exposed to water or sweat a lot, the above time will be shortened. Therefore, it is necessary to regularly reapply sunscreen. When reapplying sunscreen, you can use makeup remover to remove the previous layer. If you’re wearing makeup, use a powder sunscreen to reapply. Skip important areas Many women think that only the skin exposed to the sun must apply sunscreen without knowing that UV rays can penetrate clothes and different layers of thick and thin fabrics. If sunscreen is not applied to the entire body, many other areas of skin can still be damaged as usual. In addition, note two places people often do not pay attention to protect when going out in the sun: eyelids and lips. The lips are especially vulnerable because they don’t have a lot of melanocytes, a protective pigment responsible for giving color to skin, hair and eyes. The more hydrated your lips are, the easier it is for UV rays to penetrate deeper into unprotected skin. For lips, you can use lip balm with SPF over 30. Do not follow instructions for use For chemical sunscreen to be effective, it needs to be applied to the skin at least 20 minutes before going outside because the skin needs time to absorb the protective ingredients. It is recommended to apply evenly and thoroughly on the skin before wearing clothes to avoid any traces or stains of cream on the clothes. Particularly for products with 2 physical sunscreen ingredients – titanium oxide and zinc oxide – will work immediately after application. So with a physical sunscreen, you don’t have to wait for the sunscreen ingredients inside to take effect. Use opened sunscreen for a long time When unopened, sunscreen usually has a shelf life of about 2-3 years. However, once used, this time is reduced to about 6 months. You should not use sunscreen that has expired, has a change in texture, color or scent because it can cause allergies and damage to the skin. Do not pay attention to the spectrum index on sunscreen Many sunscreens only work against UVB rays, the cause of sunburn. Meanwhile, UVA rays also bring many harmful effects. Carrying a longer wavelength than UVB rays, UVA rays penetrate deeper into the skin, destroying collagen structures and leading to skin aging. For maximum skin protection, look for sunscreens that have broad-spectrum formulas (on the packaging that say “broad-spectrum”) that block UVA and UVB rays. For sunscreens that use the PA character, choose a product that has the PA character with plus signs after +++ or more. Using sunscreen that is not suitable for your skin Sunscreen only works when you choose the right product, suitable for your skin characteristics. Should choose a sunscreen with an SPF of 20 – 30 for light skin, an SPF of less than 20 for dark skin, if you want to increase protection in the harsh sun, only use a sunscreen with SPF 30 50 is the best fit. People with acne-prone skin should use the spray form. This type both protects the skin and unclogs the pores, helping the skin not to be blocked by dust and sweat. Sensitive skin, prone to allergies should choose sunscreen that does not contain paraaminobenzoic acid (PABA). Like other cosmetics, improper use of sunscreen is not only ineffective, it can even cause unfortunate damage to the skin. If you are making the above mistakes, you need to correct them immediately to have smooth, healthy skin this summer. Minh Hoa (th)

1. Using insufficient dosage: Applying too little sunscreen prevents the skin from receiving optimal protection from UV rays. Dermatologist in Okemos (Michigan, USA) explains on Real Simple : “With products with SPF 15, if not applied enough, the sun protection effect will be equivalent to products with SPF 8”. The amount of sunscreen the size of the palm of your hand is enough for the body. On your face, you should apply sunscreen that is the size of a dime. Image: Carilion Living. 2. Do not reapply sunscreen: Sunscreens of any kind, including water-resistant ones, degrade after 2 hours of use in the sun. If you swim or sweat a lot, the above time will be shorter. When reapplying sunscreen, you can use makeup remover to remove the previous layer. In case makeup must be maintained, reapply with a powder sunscreen. Image: Lanxel. 3. Just look at the SPF number: SPF (Sun Protective Factor) is an index that protects the skin from UVB rays (which cause sunburn). Meanwhile, UVA rays from sunlight also bring many harmful effects. Carrying a longer wavelength than UVB rays, UVA rays penetrate deeper into the skin, destroying collagen structures and leading to skin aging. Use a broad-spectrum sunscreen that says “broad-spectrum” on the packaging. For sunscreens that use the PA character, choose a product that has the PA character with plus signs after +++ or more. Image: Chophealth. 4. Failure to follow the instructions for use on the packaging: Chemical sunscreen ingredients take a while to activate their ability to absorb UV rays. When using chemical sunscreen, you need to apply it about 20 minutes before going out in the sun. This information is noted on the packaging in the instructions for use. In contrast, 2 physical sunscreen ingredients – titanium oxide and zinc oxide – will act immediately upon application. With a physical sunscreen, you don’t have to wait for the sunscreen ingredients inside to take effect. Image: Byrdie. 5. People with brown skin do not need to apply sunscreen: Dermatologist Jeanine Downie of Montclair (New Jersey, USA) said: “Dark skinned people often have a natural SPF of 5 to 8. That excess melanin can minimize the risk of burning caused by However, they are not enough to protect the skin from UVA rays – the leading cause of aging, skin cancer.” Image: Allure. 6. Apply sunscreen only to the face: Your ears, lips, and nape also need to be protected with sunscreen. As for lips, you can use lip balm containing SPF over 30. Photo: Allure. 7. Relying on Sunscreen Only: Sunscreen plays an important role in protecting the skin from UV rays. However, it’s not the only thing. When out in the sun, you should wear long, dark clothes. Outfits made of dark fabrics with tight seams provide extra sun protection. Image: The Skin Cancer Foundation. 8. Using sunscreen for too long: In unopened condition, sunscreen usually has a shelf life of about 2-3 years. If opened, this period is reduced to 6 months. Do not apply sunscreen that has expired, has changed in texture, color or scent.

Although spending many summers using sunscreen is not certain, every woman has found a product that is truly “honest”. Maybe, you have chosen a sunscreen with a great texture, applied lightly, smooth but not enough to protect the skin. Or there is a case, you believe in using a reputable and quality sunscreen but your skin is full of acne because the cream texture causes clogged pores. That’s why many women still do not stop experimenting and changing sunscreen. However, now you will not have to be confused when shopping anymore because the doctors have told you 4 steps to choose the best sunscreen for yourself. 1. Identify broad spectrum sunscreens (Broad-Spectrum) First, the American Academy of Dermatology (ADA) recommends choosing a sunscreen labeled “Broad-Spectrum,” because this means it will protect against both UVA and UVB rays. UVA rays are one of the causes of premature skin aging, causing the formation of wrinkles and brown spots. UVB rays cause sunburn, and overexposure to both can lead to skin cancer. 2. Pay attention to SPF SPF is a measure of how much UVB rays will be blocked by a sunscreen. Dermatologists recommend using a sunscreen with at least SPF 30. This is the number that New York-based Dr. Adarsh ​​Vijay Mudgil calls. “magic number” . SPF 15 will block 93% of UVB rays while SPF 30 will block 97% of UVB rays. So, using a sunscreen with at least SPF 30 is the best way to protect your skin. 3. Pay attention to your skin type “If you have acne-prone skin, make sure your sunscreen is labeled ‘non-comedogenic’ or ‘won’t cause breakout’, which means it won’t clog pores. Pores / Non-comedogenic” , according to Dr. Joshua Zeichner in New York. “If you have dry skin, you should choose a moisturizer with sunscreen, or a sunscreen that contains moisturizing ingredients such as Hyaluronic Acid, or Ceramide.” If you have sensitive skin, Dr. Emily Smith in Missouri, USA recommends choosing a physical sunscreen. This product has zinc oxide and titanium oxide that will help protect the skin, and these two ingredients will not sting or burn the skin around the eyes. Physical sunscreen will sit on the surface of your skin, creating a protective film to protect your skin from the sun. Chemical sunscreens contain ingredients such as avobenzone and oxybenzone that absorb UV rays, keeping them from penetrating the skin. These ingredients can in some cases be irritating to sensitive skin, but are easier to apply. “Chemical sunscreens are easily absorbed into the skin, leaving little white streaks” , according to Dr. David Fieleke in Missouri. 4. Is sunscreen cream, lotion, stick or spray best? Sunscreen comes in quite a few forms, and it’s up to you to choose which one: “Sunscreens come in cream, lotion, gel, spray, stick and special formulations” , according to Dr. Zeichner: “The best sunscreen is the one you can actually use” . Of course, sunscreen is only effective if you use it correctly. Dr. Zeichner recommends applying a generous amount of sunscreen with a shot of wine to all exposed areas (face, neck, hands, etc.). In addition, you also need to reapply sunscreen every 2 hours. If you use a spray sunscreen, Dr. Mudgil recommends spraying it on your hands and then using your fingers to apply it to your face to help it spread evenly. Source: NBC News Photo: Internet

Choosing the right sunscreen is as important as “choosing the right person” (Artwork) Choosing a sunscreen is like “choosing the right person”, so depending on your skin type, there will be tips for choosing your own sunscreen. Here are a few tips that you can check out. Oily skin Oily skin is the most annoying thing is the amount of oil secreted on the face that makes the skin always greasy and uncomfortable. Therefore, you should choose products with fast absorbing cream with a matte finish. Types in the form of milk or gel will be the right choice, on the product packaging there are phrases such as: Oil Control, No Sebum, For Oily Skin, Oil Free, … Dry skin For dry skin, look for sunscreen that does not contain alcohol and should contain ingredients that moisturize the skin. In addition, the ingredients table should have ceramides, hyaluronic acid, or glycerin, … will help you balance moisture, limit dehydration, dry skin, leaving skin always smooth, smooth. However, dry skin is susceptible to aging and wrinkling after exposure to the sun even though the sunscreen contains moisturizing ingredients. So, with dry skin, you should still apply moisturizer before applying sunscreen to ensure smooth moisture for skin. Sensitive skin Sensitive skin is easily irritated, so when choosing products, be careful. The ingredients table contains no alcohol or fragrance and a hint of skin care is essential for sensitive skin. Or you can choose physical sunscreens, as these lines usually rarely contain ingredients that irritate the skin, which is a good suggestion for sensitive skin. Acne skin Acne skin should use sunscreen products with benign ingredients, gel form, fast permeability, light texture, no oil, help skin dry quickly, minimize pores. Also, avoid creams that contain scents, alcohol, oxybenzone and PABA (chemical sunscreens). Therefore, a physical sunscreen (containing zinc oxide and titanium oxide) is the right choice for acne skin. Notes when choosing a sunscreen Note when choosing a sunscreen (Artwork) Not only suitable for each skin type, when choosing a sunscreen the most important thing is: SPF number SPF (Sun Protection Factor) helps measure resistance to UVB rays, the higher the SPF number, the longer the sun protection period. To measure the effectiveness of sunscreen, 1 SPF will protect the skin for 10 minutes. And want to know how long your sunscreen is effective, just multiply the SPF number by 10. For example, if your sunscreen number is SPF 20, the sun protection time will be 20 x 10. = 200 minutes = 3 hours 20 minutes is the time your skin is protected. Indicator PA PA (Protection Grade of UVA) measures resistance to UVA rays. There are 3 levels: PA +, PA ++, PA +++, which correspond to the level of UVA protection, respectively: weak (about 4 hours), medium (about 8 hours), strong (about 12 hours).

Harmful when using sunscreen incorrectly Even with enough sun protection, you can still be silently exposed to UV rays. This type of ultraviolet light has long wavelengths, penetrates the fabric, the glass and affects the skin. Over time, unprotected skin and too much sun exposure can lead to aging and reduced resistance. The face, hands, chest and shoulders are the areas of the body that are most exposed to UV radiation. Therefore, effective sunscreen clothing will be the second layer of skin to strengthen skin protection. Normally, the traditional Northern sunscreen shirt is the shirt with the sleeve or thick jeans, the South is the jacket with a hat made of polyester material. These materials do not absorb sweat, causing the body to squash, cause allergies, dermatitis, bring feelings of frustration and reduce the effectiveness of sun protection. UV rays in intense sunlight cause many harmful effects to the skin. Some people think that just shield familiar parts like the face and arms, but forget that any skin exposed to the sun also leaves a lot of harm. Therefore, choosing a standard sunscreen must first protect all areas of the body. In addition, should choose a convenient design, suitable for means of transport, especially motorcycles. Clothes that are too tight or too cumbersome will cause inconvenience and unsafe driving. In addition, dark clothing will absorb heat more strongly than light-colored shirts. Depending on the intensity of the UV rays of the day, you should choose the color of the shirt to protect your skin. Many parents think that children who are exposed to the sun will absorb more vitamin D, so sun protection is not necessary. However, a child’s immature skin is vulnerable, especially under intense sunlight. Wearing sunscreen properly will avoid many of the harmful effects of UV rays. Anti-UV with Uniqlo outfit Clothing with good sun protection must have UV cut and UPF indexes – the level of UV resistance, which is verified by reputable agencies. Sunwear with a UPF of 40 will only give 1/40 (or 2.5%) of the sun’s ultraviolet rays. In other words, it blocks 97.5% of the UV rays hitting the skin, 40 times more effective in protection than skin not covered with UV protection. Thanks to advanced technology from Japan, the anti-UV product line from Uniqlo is able to block both UV rays up to 90% (according to Japan’s JIS L 1925: 2019 certificate). Despite its high UV resistance, the product is still affordable. Uniqlo’s sunscreen has a UV blocking index of up to 90%. Not only women, even men and children also need to pay attention to sun protection. Whether working outdoors or just moving on the road, these two subjects also need to pay attention to skin protection. Uniqlo offers UV-resistant clothing for men and children only, with matching colors and designs. UV-protective clothing for kids should be cool in materials that feel light. Normal sun protection can only block the heat from the street, but not UVA / UVB rays. While UVA rays are the cause of wrinkles or skin cancer, UVB rays are the main cause of sunburn. Due to being made from the type that absorbs or reflects UV light (chemically treated), Uniqlo’s sunscreen protects the skin instantly without taking too many steps. In addition, Uniqlo’s lines of hats, hats, glasses and gloves also apply UV protection technology for many years. This will be a good choice for sun protection in the coming summer.

1. Wrinkles are the first signs of skin aging: Many people don’t care about skin aging until they see wrinkles appear. However, aging can result from changes in skin color and texture. Dermatologist Jason Emer of Beverly Hills (California, USA) explains above Real Simple : “Dark spots, thinner skin are the first visible signs of aging. On the other hand, there are dark circles or sunken skin under the eyes, folds around the mouth.” It’s never too early to start a skincare routine. Image: Siena. 2. Aging is determined by genes: The aging process of mother and child is not exactly the same. Dermatologist Joshua Zeichner in New York (USA) said: “Aging is determined by both internal and external factors. Some people are genetically fortunate with a young appearance. UV, environmental pollution can lead to rapid aging in even carriers of good genes. ” Image: Jangjina_. 3. Only apply sunscreen when going out: Don’t skip the sunscreen even if you spend all day indoors. Whether it’s cloudy or rainy, UV rays are present. UVB rays cause sunburn, damaging the skin epidermis. Meanwhile, UVA rays are associated with cell aging deep below the skin. It causes wrinkles and brown spots. Window and curtains can block UVB rays, but not UVA rays. Image: Ugeniesm, Shutter. 4. See immediate anti-aging results: Dr. Joshua Zeichner said: “I tell my patient it takes weeks or months to see the benefits of most skin care products.” Usually, exfoliants or moisturizing hyaluronic acid show immediate results. Image: L’Oreal Paris, Tea with MD. 5. Expensive cosmetics bring higher efficiency: Don’t spend too much money on cosmetics, you can still get a bright, youthful look. Dermatologist Konstantin Vasyukevich from New York (USA) explains: “Valuation in skin care sometimes reflects marketing activities, brands rather than quality”. According to Mr. Vasyukevich, simple and affordable skin care treatments are sometimes more effective than expensive beauty solutions. “Using sunscreen, daily moisturizer in the long run will be much better than expensive treatments later on,” he said. Image: Healthline. 6. Night skincare routine is more important than day: Skin has different needs from time to time. During the day, skin needs to be protected from UV rays and environmental pollution. These are the leading causes of premature aging. At night, the skin recovers and regenerates. Without proper protection during the day, the skin cannot be healthy even with careful care at night. Image: Awebtoknow. 7. Skin burning or stinging shows that cosmetics are promoting effects: Unlike muscle training, the burning sensation during skin care is not a good sign. Your skin is irritated, potentially at risk of acne. On the other hand, this is also a sign that the skin barrier is weakened. From there, the skin is susceptible to damage and rapid aging.

Ultraviolet rays are invisible rays, part of the energy coming from the sun, that can burn skin and cause skin cancer. UV radiation is made up of three types of rays – ultraviolet A (UVA), ultraviolet B (UVB) and ultraviolet C (UVC). UVC is the most dangerous type of ultraviolet rays, but it cannot penetrate the ozone layer of the atmosphere, so it is not harmful to the earth. UVA and UVB rays – are the most harmful substances, of which 95% are UVA rays and 5% are UVB rays. UVB rays often affect the outer layer of the skin, damaging the skin. UVB rays cannot pass through glass windows, but are strongly reflected from snow, water surface, asphalt, causing burns … It can lead to some types of skin cancers such as melanoma, carcinoma. basal and squamous tissue. UVA rays are much less intense than UVB rays but reach the deeper layers of the skin about 50 times and cause more damage than UVB rays. UVA rays penetrate thin materials such as windows, clothes, clouds … so even if it’s shady, or cloaked in sun-protective clothing, our skin is still heavily affected. This ray does not cause immediate blackening of the skin like UVB, but causes skin aging and immunodeficiency, it also affects the basal cell layer of the epidermis, where most skin cancers arise. Although the acute effects of UV are usually short and reversible. But the long-term effects of UV rays are much more serious and dangerous, which can be life-threatening, including aging of the skin, suppression of the immune system, eye damage and skin cancer. For this reason, it is often recommended to use a sunscreen to block both of these types of radiation. How to use sunscreen? When the skin has been severely damaged by UV damage and the skin has lost significant collagen, lax cell connection, treatments, including modern aesthetic methods, have partly improved, but It is very difficult to give back healthy skin because at this time the cell’s DNA is damaged. Therefore, it is essential to do immediately to prevent the skin from getting sunburned. First of all, it should be minimized when going to the street when the sun is heavy and need to take measures to protect the skin when going out in the sun with a hat / hat, jacket and sunscreen. Protect skin by wearing a hat and sunscreen 30 minutes before going out in the sun. For the sunscreen to be effective, apply sunscreen to areas of skin that must be exposed to direct sunlight 20 minutes before going out. For the skin already with clothing support, you just need to apply an appropriate amount to the skin. For areas exposed to direct sunlight, sunscreen should be reapplied every two hours. Going outdoors, sunscreen should be reapplied every 2 hours. The shelf life of conventional sunscreens is 3 years under normal room temperature conditions. If placed in an environment that is too hot or too cold, the product quality will suffer, thereby disabling their functionality.

Enough sun protection technology At the UV100 store (Nguyen Dinh Chieu, District 3, Ho Chi Minh City), a pair of gloves costs more than 500,000 VND, many times higher than a pair of normal gloves which only costs about 20,000-30,000 VND. According to the salesman’s recommendation, this glove is both 99% UV resistant and antibacterial; able to dissipate heat, cool quickly due to the breathable fabric … Other products with anti-UV effects also have a sky-high price. Coat over 1 million VND, UV400 glasses over 600,000 VND / piece, mask over 100,000 VND / item … These products are tested for quality and UV protection by an accrediting agency of … Australia. Sunscreen shirt priced at 140,000 VND is introduced by a shop with enough technology with 99% sun protection. At 365 wholesale garment factory Vo Thanh Trang (Tan Binh district, Ho Chi Minh City), we were introduced to many multi-purpose instant sunscreen models including hats, masks, shirts, skirts and the selling price of only 125,000 VND / product. Products. The seller said that the product is made from Japan’s UPF 40 UV Cut anti-UV technology, which protects the skin from 95% of UV rays without applying sunscreen. On the products of the shirt there is no information of the manufacturer other than the words “VNXK” – exported Vietnamese goods. Also at another website specializing in selling mother and baby, many sunscreen products are being sold and introduced themselves according to the latest Japanese AIRISM technology. The selling price is only 140,000 VND / product. Some Japanese fashion brands such as Uniqlo are famous for using UV-resistant fabrics for their sun protection jackets and their product prices in this fashion chain are not less than 1 million VND. However, these products are also being copied and sold at many points and individuals for only 200,000-300,000 VND / product. The common point of selling ambiguous quality is that often the reason fabrics with UV protection cannot distinguish the quality of fabrics with the naked eye. Accompanied by a series of … international certificates. Anti-UV, no need for specialized products According to Assoc.Prof. Dr. Nguyen Manh Tuan – Deputy Director of the Institute of Applied Materials Science, there are many forms of radiation around us, high-energy radiation is electromagnetic, low-energy radiation is infrared. UV rays are classified as high energy radiation, capable of penetrating deep through clothing and causing damage to the skin. There are three types of UV rays: UVC (short wave light), UVB (strong impact on the skin’s surface, causing redness, sunburn and skin cancer risk), UVA (with the longest wavelength, penetrating depth). under the skin, causing skin aging and wrinkling). UPF index is an index evaluating the level of protection of a fabric material from UVA, UVB rays. The higher the UPF index, the lower the amount of UV light penetrating the fabric. An effective sunscreen should be made from fabric with a UPF rating of 15 to 50+, which is about UPF for the best skin protection. Normally, synthetic fibers such as polyester or nylon will be more resistant to UV rays than cotton. Depending on the fabric material that can block UV rays, at different levels. If the fabric is resistant to UVA and UVB rays, the manufacturer must add anti-UV chemicals (this chemical is also known as UV). But whether the chemical is good or not, the ability to resist UV rays, the index of any number must be tested and certified by the Vietnam Textile Institute. “Cheap products on the street, because there are no measuring tools to check, so I do not know for sure what materials they use, whether they are dyed with anti-UV chemicals or not, how much UV protection is. If they use materials that are not good enough, do not dye UV chemicals but increase the product thickness, they can also block UV rays, just the level of resistance can not be maximized as advertised “, Assoc.Prof.Dr. Nguyen Manh Tuan said. Dr. Huynh Khanh Duy – Chemical Engineering Department, Ho Chi Minh City University of Technology said that no matter what material a product is made of, as long as UV rays cannot be penetrated, it is able to protect against the sun. Therefore, whether it is synthetic fiber fabric, cotton fabric, denim fabric, khaki … just thick enough is enough to effectively protect against the sun but the price is quite cheap. But in return, these products can not bring the desired coolness in the hot sun. “With products dyed with anti-UV chemicals, depending on the type of chemical used well or not, the dye will pass through the washing times. Many products on the market today do not announce how much UV protection, so UV resistance is also in the form of … bad luck.
