There are several prescription injections that are FDA-approved for temporarily improving wrinkles or padding the face to look younger. Some of the better-known names include Botox, Restylane and Juvederm, but there are lots of others. Sclafani and Katz say the reasons to use platelet-rich plasma instead of other injections is that the plasma is "natural" and doesn't carry the risk of allergy or rejection—because it's your own blood.

So, what is it and how does it work, exactly? Don't let the name fool you. In fact, "It's usually done in full light of day," says Beverly Hills-based dermatologist Ava Shamban. In all seriousness, the treatment is a "combination of a microdermabrasion, followed by the application of PRP (platelet-rich plasma)," says Shamban. "The PRP is derived from the serum portion of the blood, which contains platelets. The platelets contain high levels of growth factors, which, when applied to the skin, will stimulate cell turnover."
