Botulinum Toxin
Star Power: Injections of botulinum toxin (brand names Botox and Xeomin) smooth away wrinkles by blocking the nerve impulses that cause muscle movement. When Botox was approved for cosmetic use in 2002, many patients wound up trading wrinkles for immobile eyebrows. In the years since, doctors have mastered how to smooth lines without making people look petrified or poker-faced. In fact, doctors now inject less toxin with each treatment than they used to. Expect results to last about three months at first. "After you've used botulinum toxin for a couple of years, it will last closer to six months," says Cheryl Karcher, MD, a New York City dermatologist. "And I have some patients who need only yearly touch-ups."Who Might Benefit: Anyone who wouldn't miss her expression lines. Botox and Xeomin are FDA approved to treat frown lines (the "11s" between the brows) but are frequently used "off-label" to uncrinkle crow's-feet and horizontal forehead lines. Some doctors also use botulinum toxin for trickier applications: to soften vertical lines in the neck, for masseter reduction or between the breasts, to smooth puckering around the lips, and to lift the corners of the mouth.
You Should Know: Toxin injections can cause bruising. If injected incorrectly, they could also leave you with a droopy eyelid or—when used around the mouth—a drooling problem. "There are no long-term adverse effects caused by FDA-approved botulinum toxin," says Arielle Kauvar, MD, "but an unskilled doctor can create some pretty embarrassing, if mercifully temporary, side effects." So be sure you go to someone who knows what they are doing, and have been doing it for years.
Hyaluronic Acid Filler
Star Power: When applied topically, hyaluronic acid subtly plumps the skin for hours. When injected, it dramatically plumps the skin—for months. In the decade since Restylane, the first hyaluronic acid filler, was approved by the FDA, doctors have learned to use these injectables not only to soften the lines that can't be smoothed with Botox (the nasolabial folds) but also to replump the contours of the face that gradually lose definition (the cheekbones) or become hollow (the temples). Research has now shown that hyaluronic acid fillers can even help reverse aging by encouraging the skin to produce more collagen.Who Might Benefit: If you want to plump your lips or smooth your nasolabial folds, consider Juvéderm. Radiesse and Voluma XC are a bit thicker (and sometimes last longer) and are ideal for restoring volume around the cheekbones and along the jawline. Belotero was FDA approved in 2011 and is favored for filling the hollows under the eyes: It won't create the bluish tinge that other hyaluronic acid fillers can leave when injected beneath thin skin.
You Should Know: Juvéderm, Radiesse, Belotero and Voluma can include lidocaine to ease the pain of injection, but it still stings. You may bruise and can expect some swelling for about 24 hours after an injection.
Fractional Nonablative Laser (Pixel Laser Treatment)
Star Power: With pixilated beams of light, this laser can boost collagen, smooth wrinkles, and in some cases break up pigment beneath the skin—without the weeks of redness, swelling, and peeling that accompanied its predecessors. Only a fraction of the skin is targeted with each treatment; after about five, you have "resurfaced" your face, giving you a profound improvement in skin texture, and even some tightening.Who Might Benefit: Are fine lines and roughness your issue? The Pixel minimize lines and leave skin luminous. If discoloration is your problem, consider the Photofacial. It uses two wavelengths of light: One remodels collagen for smoothing; the other erases age spots.
You Should Know: Fractionated lasers leave your skin red and peeling for several days. Even with topical lidocaine, you'll experience heat and stinging during each treatment.
Chemical Peel
Star Power: A chemical peel, in which an acid solution is painted on the skin to lift away the upper layers, minimizes discoloration, smooths lines and crepiness, and even—when done deeply enough—helps tighten the skin.Who Might Benefit: If you want a glow for a few days, a glycolic peel is your best bet. To reduce breakouts, try a series of salicylic acid peels, such as the Jessner Peel. A Vitalize peel or Jessner Peel can improve pigment. To improve the skin on your chest, back, or hands, a chemical peel is a great option.
You Should Know: Some peels, like the Jessner Peel, yield dramatic results in one treatment—but leave skin red and peeling for up to ten days. Light glycolic peels require little downtime but have a less transformative effect.
