On National Sunscreen Day, which is part of National Safe Sun Week, rub and absorb that lotion, cream, or spray before enjoying the warmth and light of summer. The higher the sun protection factor (SPF) in your product, the better. Chances are if you don’t know the right balance of SPF to protect yourself and still get the tan you want, a friend will. If they ask why, just say, “Don’t fry!”
