This Is What Microneedling Really Does to Your Face

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. Sound appealing? Not so much. But this minimally invasive treatment—whether it’s done in-office by a trained aesthetician, dermatologist, or plastic surgeon, or at home using a dermaroller (a small, handheld paint roller coated in tiny needles)—is virtually painless and incredibly 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 board-certified dermatologist and RealSelf contributor Sejal Shah, MD. (It works the same way lasers do, only you’re injuring the skin mechanically instead of using heat or light.) Believe it or not, microneedling benefits caught the eye of skincare fanatics interested in anti-aging.
