As you age, your skin changes. Your body doesn't produce as much collagen, and the elastin that allows skin to spring back into place gets weaker. You also don't create or lose skin cells as fast. To boost aging skin, exfoliate to remove dead skin, use a nondrying soap, and moisturize often. Use over-the-counter retinoids to reduce fine wrinkles, or ask your doctor about a prescription version. Most of all, stay out of the sun.
