When to Wear Sunscreen? Always.
If you want to look younger and decrease your chance of skin cancer, smear it on your face and ears every day. A recent Australian study illustrates exactly the kind of outward difference this makes. Researchers had silicone molds made of 900 people's skin that depicted coarseness, wrinkling, and elasticity. Half the group was instructed to wear sunscreen daily, and the other half put it on only when they thought they should (at the beach, for instance). Four and a half years later, the researchers found that the sunscreen group had 24 percent less skin aging than those who used it only occasionally. Other evidence shows that daily UV protection reduces rates of melanoma, which are especially high in men. (Men are 55 percent more likely than women to die from the cancer.) The simplest way to protect yourself is to use a moisturizer with SPF — we suggest Neutrogena Healthy Defense Daily Moisturizer SPF 50 ($15) — every morning. When your entire body is exposed, go for the water-resistant beach stuff.
