7 Things Men Don't Know About Their Own Bodies

The Have the Ability to Slow the Aging Process—if They're Careful

From the neck up, men tend to age better than women: They lose collagen density more slowly than women, which means their skin resists wrinkles and sagging as they get older. Dermatologists claim that both men and women lose about 1 percent of collagen per year after age 20, but the loss accelerates significantly in women when they hit menopause. But because men are often more lax about taking care of their skin than women are, they're more susceptible to sun damage and shaving-related surface trauma, and this can negate their natural advantage. Daily use of broad-spectrum sunscreen goes a long way toward helping men retain their skin's suppleness and vitality.
