WHY DOES SPF MATTER WHEN SELECTING A SUNSCREEN?
It is summer, and you may need sunscreen more than anything. If you spend time outside, the chances are that you may have heard about how essential it is to wear sunscreen before you step out.
While wearing sunscreen is better than not wearing any, if you choose, it is best to choose a sunscreen with broad-spectrum UV protection of at least SPF 30.
HOW DO SPF MATTERS?
SPF also means sun protective factor in sunscreen helps block your skin from sun radiation. The sun emits two kinds of radiation: UVB and UVA rays. While UVB rays are more carcinogenic and often responsible for sunburns, UVA rays contribute to the signs of aging in the skin. These include sagging and wrinkles. In addition, UVA rays make UVB rays more reactive, so if they both combine, it could be deadly for a human.
HOW TO CHOOSE THE BEST SUNSCREEN?
If there’s low sun exposure, makeup or moisturizer with a base of SPF 15 is sufficient. However, you may want to consider your outdoor activity in other situations. It helps to determine what type of sunscreen you must use.
