Sip a youth elixir

Enjoying a daily collagen “latte” can fight skin aging. “Starting at age 40, your body begins making less collagen, and the collagen it does make is less elastic, so your skin, hair and nails aren’t as firm,” says Dr. Gottfried. To boost collagen, she advises blending 1 cup of coffee or tea with 1 to 2 Tbs. of collagen powder (one she likes: Great Lakes Gelatin Collagen Hydrolysate, $26 for 16 oz., Amazon.com) until frothy.
