8 mistakes when using sunscreen

Using the wrong sunscreen will damage your skin.

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.

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.
