- According to a research, the breakdown analysis of SPF states that SPF 30 protects 97% of UVB rays, SPF 50 protects 98% and SPF 100 protects 99% of the UVB rays.
- The American Dermatology Academy recommends using sunscreens whose SPF is equal to or greater than 30.
- The sunscreens come in a different type of fragrances such as the combination of beachy scent with floral, baby powder, citrus, woodsy or tropical notes.
Why we need a sunscreen?
