At first, it may seem strange to roll hundreds of tiny needles over your skin. But that’s exactly what microneedling devices — a.k.a. derma rollers — do, and these handheld tools have made a name for themselves in the beauty world as a DIY solution to a variety of cosmetic skin woes.
While not tons of research has been done on their effectiveness just yet, dermatologists do seem to agree that derma rollers can stimulate collagen production and, in turn, improve the appearance of skin. The practice of microneedling started in dermatologists’ offices, but now, derma rollers are widely available for at-home use, too.
