Best sunscreen for skin lets go and learn –
Wearing sunscreen is one of the best — and easiest — ways to protect your skin’s appearance and health at any age. Used regularly, sunscreen helps prevent sunburn, skin cancer, and premature aging. To help make sunscreen a part of your daily routine, dermatologist Anna Chien addresses common concerns.
How does sunscreen work –
Physical (mineral) sunscreen ingredients (including the minerals titanium dioxide and zinc oxide) block and scatter the rays before they penetrate your skin. Chemical sunscreen ingredients absorb UV rays before they can damage your skin.
SPF is a measure of how much UVB light sunscreen can filter out. Dermatologists recommend using an SPF of at least 30, which Adarsh Vijay Mudgil, MD, a dermatologist practicing in New York, calls “the magic number”. SPF 15 blocks about 93 percent of UVB rays, while SPF 30 blocks about 97 percent of UVB rays.
