Sunscreens come in many forms: spray, gel, patch or topical… but generally contain physical or chemical ingredients that are able to block, absorb or spread some UV radiation on the area. skin exposed to the sun. The 3 types of UV filters that can be combined in sunscreen products are: Organic chemical compounds that can absorb harmful components of UV light (oxybenzone, sulisobenzone, avobenzone). Inorganic particles reflect, scatter and absorb UV light (titanium dioxide, zinc oxide, superoxide dismutase, phlebodium aureum). Organic particles that can reflect, scatter or absorb light (tinosorb M, tinosorb S, mexoryl XL.). The American Cancer Society recommends that people use sunscreen because it can help prevent squamous cell and basal cell skin cancers, and to use broad-spectrum sunscreens because they can provide Protects against both UVA and UVB rays. What is SPF sun protection factor? SPF (Sun Protection Factor) is a measure of the amount of UV radiation needed to create a sunburn on the skin. All sunscreens are tested to measure the amount of UV radiation exposure needed to cause sunburn when sunscreen is used compared with UV exposure to cause sunburn without sunscreen. Sunscreen. The product is then labeled with the appropriate SPF value. The SPF value indicates the level of sunburn protection provided by the sunscreen product. As the SPF value increases, the level of sunburn protection increases. Sunscreen is only effective when applied to the skin about 15 – 30 minutes before going out in the sun. Should choose sunscreen products with medium SPF, in the city only need to use products with SPF 20 – 30. A very common misconception is that consumers are often told that an SPF 15 sunscreen can provide 15 x 10 minutes = 150 minutes of sun protection without sunburn. This is not true because SPF is not directly related to the time of sun exposure but to the amount of energy exposed to solar radiation. Although the amount of solar energy is related to the length of exposure to the sun, there are other factors such as the intensity of the solar energy that can affect the amount of UV radiation. For example, the following exposures could result in the same amount of solar energy (because the sun is more intense at noon than at other times): Example 60 minutes of solar energy at 9 morning hours can be equivalent to 15 minutes at 13 pm. The intensity of UV radiation in sunlight is also related to geographical location, greater radiation intensity occurs at lower latitudes. Several other factors can affect the amount of solar radiation exposure bức – People with fair skin are able to absorb more solar energy than people with dark skin under the same conditions. – The more sunscreen used, the less solar energy is absorbed. Sunscreen wears out and becomes less effective over time so frequency of reapplying is important to limit absorption of solar radiation. The frequency of reuse is also affected by the activities the user engages in. For example, when swimming, sunscreen needs to be reapplied more often because water can wash sunscreen from the body. In addition, high levels of physical activity also necessitate more frequent use of the cream because this activity can cause heavy sweating that washes away the sunscreen. Because many different factors affect the amount of solar radiation, the SPF number does not reflect the length of time a user is in the sun. In other words, SPF doesn’t inform users about how long they can stay in the sun without getting sunburned. Instead, SPF is a relative measure of the amount of sunburn protection provided in a sunscreen. Different sunscreens will have different SPF ratings. There are sunscreens with SPFs between 15 and 100 on the market today, allowing consumers to compare levels of sunburn protection. The higher the SPF, the more protection your skin can get from the sun. But 3 times the SPF does not mean 3 times the UV protection. For example, SPF 20 sunscreen can absorb up to 95% of UV rays, while SPF 60 sunscreen can absorb up to 98.3% of UV rays; SPF 15 blocks 93% of UV rays; SPF 30 blocks 97% of UV rays; SPF 50 blocks 98% of UV rays. In Vietnam, you should choose a sunscreen with an average SPF, in the city you only need to use a product with an SPF of 20 – 30, when you go to the beach, you need to use a sunscreen with an SPF of 50+. In fact, the majority sun protection index is often not as advertised. Some surveys show that over 40% of sunscreen products with SPF sun protection do not reach the level stated by the manufacturer on the product.

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.

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.

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).
