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

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.

1. Read the label before you buy: First, you need to consider the SPF factor of your favorite sunscreen.

Check the SPF: “Sunscreen’s SPF 30 will block 97% of the harmful rays from the sun,” said dermatologist Seth Forman from the Institute of Dermatology and Skin Cancer. At the same time, you must pay attention to the PA rating – the more marks + the higher the skin protection. Try to buy a sunscreen that has at least PA +++ protection. Because both SPF and PA work in parallel to protect the skin, preventing sunburn as well as damage from penetrating deeply inside the body. Image: parade. 3. Water resistance: “Water-resistant sunscreens are great for hot days or when playing sports,” says Dr. Forman. “However, these products are sticky and need to be reapplied every 2 hours.” Besides, the sunscreen only remains effective under water for 40-80 minutes. Therefore, you must reapply regularly for best results. Image: freepik. 4. Avoid allergens: Our skin becomes more sensitive each summer comes. Choose products that have no preservatives, strong scents, and the ingredients PABA or oxybenzone. People with allergies and reddened skin conditions should avoid alcohol-based formulations.

Broad spectrum search: SPF is important, but make sure your sunscreen says “Broad Spectrum” to protect against both UVA and UVB rays. UVA rays penetrate the skin deeper causing wrinkles and brown spots. On the other hand, UVB rays cause skin redness, burning and damage to the outer layers, even skin cancer. Image: leisure pro. 6. Consider skin type: Many sunscreens are tailored to each skin type. People with dry skin should look for glycerin, lanolin, oils and silicone-based ingredients. Avoid alcohol-based sprays or gels. Oily skin should look for gentle options like gels with a silica or isododecane component. People with sensitive skin need to invest in a hypoallergenic and fragrance-free sunscreen with a choice of minerals with titanium dioxide or zinc oxide.
