Stay out of the sun

Avoiding too much sun can head off skin cancer, and it can also keep you looking young by preventing wrinkles, fine lines, and saggy skin.

It’s never too early—or too late—to add sunscreen to your daily skin-care regimen (look for an SPF of 30 or higher). And don’t focus only on your face. Sun damage spots and splotches on your chest and neck will also make you appear older.
