Skin-Smoothing Shots

Autologous (your own) fat
The procedure for this injectable is two-part: First, fat is removed from fatty areas of your body (such as the hips or stomach area) through a small needle connected to a syringe, and second, that fat is injected into wrinkles, lines between the mouth and nose and even on the backs of hands (where the skin thins with age).

Cost: about $500 plus the cost of the fat transfer (about $500).

Lasts: about 6 months.

Possible side effects: minimal redness, swelling and bruising. Also on the horizon is hyaluronic acid—the jellylike substance that fills in the space between collagen and elastin fibers and decreases with age, contributing to sagging skin. While it hasn't been OK'd yet for use as an injectable in the United States, experts anticipate that it will be approved by the Food and Drug Administration (at a cost of about $300 per visit).
