If plumping your face with a filler is the kind of thing you go for, you might want to talk to your dermatologist about the newest option: Evolence, a collagen made from pigs' tendons. (We had to ask: What if you keep kosher? No problem; the product was developed in Israel and has rabbinical approval, says David Goldberg, MD, clinical professor of dermatology at Mount Sinai School of Medicine.)
Dermatologists are excited about Evolence because of its longevity. While other collagens have been around for decades (derived first from cows, then lab-grown human foreskin tissue) and give natural results with minimal bruising and swelling, they last only three to six months. "But Evolence lasts nine to 12 months," says Goldberg, who recommends the thickish formula for filling deeper folds, like those that may run from the nose to the mouth. A less viscous version of the product, called Evolence Breeze, is in clinical trials and should be available late next year; it will be more appropriate for plumping lips (or the fine lines around them).
