Simply put, microneedling is the insertion of very fine short, sterilized needles into the skin for rejuvenation, explains Macrene. Microneedling creates microscopic punctures in the skin. Here, dermatologist Macrene Alexiades, MD, Ph.D., who has published extensive research on microneedling, and Yale clinical professor and dermatologist Mona Gohara, MD, demystify the multi-purpose treatment. As a result, the mesmerizing (albeit bloody) process stars in tens of thousands of videos.
The practice dates back to 1995 but has gained significant traction in recent years thanks to new technology-and YouTube and Instagram.
It's also a standard treatment for fine lines and wrinkles, sun damage, and stretch marks. The minimally invasive treatment can be used all over the body-from scalp to ankles-to improve the appearance of scars, boost collagen, or encourage hair growth. Every dermatologist we interview can’t stop talking about the benefits of microneedling.
