What is microneedling?
Microneedling (also known as collagen induction therapy) involves using fine needles to create hundreds of tiny, invisible puncture wounds in the top layer of skin. It may not sound appealing. But this minimally invasive treatment—whether it’s done in-office by a trained aesthetician, dermatologist, or plastic surgeon or at home using a derma roller (a small, handheld paint roller coated in tiny needles)—can be very effective. “The micro-injuries you create stimulates the body’s natural wound healing processes, resulting in cell turnover and increased collagen and elastin production, therefore reversing as well as preventing signs of aging,” says Sejal Shah, MD, a dermatologist in private practice in New York City. (Microneedling works the same way lasers do, only you’re injuring the skin mechanically instead of using heat or light.)
Microneedling may reduce fine and deep wrinkles
One of the main benefits of microneedling is its ability to stimulate the growth of collagen and elastin, which is the key to new, youthful-looking skin. Because of its ability to trigger the generation of new skin cells, dermatologists have found that a few sessions will noticeably reduce fine lines, crow’s feet, and deep wrinkles on the forehead. “This is one of the reasons I like microneedling—because it’s able to use the body’s own natural healing mechanisms, so the results are very natural,” Dr. Shah says. “And because there’s minimal downtime with it, I often recommend it as maintenance for people who are trying to stave off the signs of aging.” To treat wrinkles, a needle no longer than 1.5 mm should be used. These are the 17 skin-care tips dermatologists follow themselves.
