If you look in the mirror and see something you’d like to improve about your skin — whether it’s minimizing scars, reducing wrinkles, evening out skin tone, or simply achieving a more radiant glow — micro-needling could be the answer.
At first, it may seem strange to roll hundreds of tiny needles over your skin. But that’s exactly what micro needling 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 micro needling started in dermatologists’ offices, but now, derma rollers are widely available for at-home use, too.
How Do Derma Rollers Work?
Derma rollers create tiny punctures in the outermost layer of the skin, which can lead to the production of more collagen, the bodily protein that gives skin its firmness, strength, suppleness, and elasticity, says Ellen Marmur, M.D., a New York City-based dermatologist.
They can also help stimulate the lymphatic system, leading to more radiant skin and less puffiness, she adds.
And while the devices may be newer, the practice of micro needling itself has been used for centuries, says New York City-based dermatologist Anna Avaliani, M.D.
What Should Derma Rollers Be Used For?
Derma rollers can help minimize and prevent fine lines from becoming visible or deeper on the face, neck, and chest, Dr. Avaliani notes.
Along with promoting the production of collagen and elastin for smoother, firmer, and younger-looking skin, they can be used to reduce the appearance of acne scars or stretch marks, and can even stimulate hair growth.
“If your concern is aging, dark spots, or acne scars, a derma roller could be helpful,” says Dr. Marmur.
