7 Ways You're Aging Your Skin
The No. 1 way you’re aging your skin? Not wearing sunscreen daily.
“The sun is the primary cause of skin aging,” says Neil Sadick, MD, a New York City–based dermatologist. The sun can reach you on cloudy, rainy, or snowy days as well. Plus, Dr. Sadick adds, “skin-damaging UV rays can penetrate through glass, so you need to apply sun protection even indoors.”
He suggests choosing a broad-spectrum sunscreen, which blocks both types of UV rays, UVA and UVB, with an SPF of at least 30. Antioxidant-fortified formulas containing ingredients such as resveratrol, vitamin C, idebenone, or coffee berry can offer additional protection.
