The treatment is called microneedling or derma rolling, and it involves a tool with super tiny needles that is rolled over the face or body, which causes microscopic holes in the top layer of your skin. This "precise injury," as the pros call it, stimulates elastin and collagen, both of which keep your skin firm —but the naturally-occurring stuff is lost as we age.
You can get microneedling treatments done in-office with a dermatologist or esthetician, or there are at-home tools. While in-office treatments are more potent, the process is similar. "With microneedling, tiny needles are gently pressed with even pressure against the skin and undetectable micro-wounds are created, which triggers skin to go into repair mode and produce more collagen," says Hadley King, MD, a board-certified dermatologist in New York City.

At-home devices don't penetrate as deeply as professional treatments since the needles are generally only 0.25 millimeters in depth. In comparison, needles used for in-office procedures tend to be 0.5 millimeters to 1 millimeter. And, you don't have to worry about at-home derma rollers being painful— since the needles are smaller, it will just feel a bit prickly, and it can be uncomfortable if you apply too much pressure.
These are the best derma rollers, according to customers:
That said, you want to watch your pressure and be sure to not roll too hard— this is where someone can overdo it and cause irritation or infection, warns Dr. King. Because the needles are not as long, they likely don't go deep enough to stimulate collagen, however they can help product sink further into the skin, she notes. This makes post-derma rolling a good time to apply your serums and moisturizers—for example, ones for anti-aging, brightening, or for targeting acne and scars.
Besides watching your pressure, the important step to never skip in microneedling is cleaning your tool. After every use, wash it with warm, soapy water and let it dry. Then use rubbing alcohol or hydrogen peroxide to sterilize it. At-home derma rollers can be used twice per week, and in-office produces done 1-2 times per month, says Dr. King.
