Hormones are among the most powerful anti-aging ingredients.

According to researchers and the New Beauty blog, hormones like DHEA and melatonin work wonders on the skin, replenishing its youthful glow; lessening fine lines and wrinkles.

Hormone based skin products used to be available by prescription only, and they proved much more powerful than on-the-shelf style applications. The safety of estrogen supplements remains a hot debate, but topical applications have been filled with ingredients that mimic those of estrogen. The loss of estrogen is characteristic of menopause, resulting in dull, dry, and wrinkled skin.

The idea is that what is good for the body on the inside is good on the outside, too.
