Every dermatologist we interview can’t stop talking about the benefits of microneedling. 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.
The practice dates back to 1995 but has gained significant traction in recent years thanks to new technology—and YouTube and Instagram. The mesmerizing (albeit bloody) process stars in tens of thousands of videos. 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.
Microneedling creates microscopic punctures in the skin.
Simply put, microneedling is the insertion of very fine short needles into the skin for rejuvenation, explains Macrene. The most popular (and cost-effective) microneedling device, known as a dermaroller, comprises micro-fine needles that range in diameter from 0.5 and 2.5 millimeters. But, if the prospect of multiple needle wounds sounds slightly ominous to you, know that the punctures are more like pin-pricks that enter only surface-level deep.

You can get it in-office or do it at home.
“The benefit of getting microneedling done by your dermatologist is that it can be done with PRP, which makes it more efficacious,” Gohara says. But the drawbacks are that you have to schedule time for the treatment and that it may be more expensive. “If you’re doing it at home, it’s less effective, but you can do it as you please.”
Microneedling offers fairly immediate results.
“From microneedling alone, you will look plump, pink, and luminous for a couple of weeks. On a short-term basis, it plumps the skin and makes the skin look more radiant from inflammation and very superficial swelling,” Alexiades says.
But microneedling also promises improvement over time.
According to a 2008 study, skin treated with four microneedling sessions spaced one month apart, produced up to a 400% increase in collagen and elastin six months after completing treatment.
You can supercharge it with a serum.
“I love using a hydrating serum with hyaluronic acid with a dermaroller,” Gohara says. “I revel in the opportunity to drive in hydration. Antioxidants and Niacinamide are favorites as well.” We also love a serum-drenched sheet mask right after a dermarolling session at home.
There have been significant breakthroughs this year.
“Microneedling with radiofrequency uses the added technology of flow needles to deliver radiofrequency energy into the dermis,” Gohara says on an in-office option. “The radiofrequency energy heats the dermis, causing collagen production and tissue tightening.”
Microneedling stimulates dormant hair follicles.
The stimulation of dormant hair follicles equals new hair growth, confirms Gohara. In a recent study, 100 test subjects were divided into two groups. One set was treated with minoxidil lotion, and the other received minoxidil lotion plus microneedling. After 12 weeks, 82 percent of the microneedling group reported a 50 percent improvement versus 4.5 percent of the minoxidil lotion-only group.
Microneedling can also work to reduce cellulite.
Alexiades works with a new crop of microneedling devices like the Profound by Candela. She uses the machine for crepe-like fine lines as well as sagging skin and cellulite.
Your dermaroller plays well with other skincare treatments.
Alexiades recommends pairing microneedling with topical treatments (like her 37 Extreme Actives anti-aging cream or serum) and lasers. “Often, we use this as an opportunity to apply anti-aging preparations that will penetrate better through the needle punctures. When you combine with topicals, you have a shot at some collagen building. When combined with radiofrequency, you can see tissue tightening over months,” she says.
DIY microneedling is legit…

As long as your dermatologist approves! Gohara cautions that those with eczema, rosacea, acne, and perioral dermatitis should avoid rolling at home, as it might cause flare-ups. For a gentle introduction to at-home microneedling, try the Beauty Stamp from celebrity skincare guru Nurse Jamie. The handheld tool works just as the name suggests, by stamping the skin with ultra-fine pin-pricks designed to increase your topical treatments’ efficacy and boost collagen (just like a traditional dermaroller).
It’s possible to OD on microneedling.
Frequent microneedling can lead to broken capillaries “and predispose skin to a plastic look if you over abuse it with repeated microneedle insults,” says Alexiades. Instead, curb dermaroller dependency by sticking to a once-a-month plan and always allowing full recovery between roll-sessions.
You need to be gentle on your skin after microneedling.
“Let the skin chill after microneedling,” Gohara says. “For the rest of the day, don’t wash the skin, expose it to high heat, sweat too much (that means no sun, no gym, no hot yoga).” Instead, load up on skin-loving products like the ones below:
How will you know it’s working?
Marks will appear less noticeable, wrinkles will be finer, and your skin’s quality will be overall healthier.
Microneedling alone only gives temporary results.
Dr. Alexiades notes that a recent AAD study showed that microneeedling alone can only give temporary results that do not last. “As my over ten years of research has shown, you must combine microneedles with radiofrequency to get long term wrinkle and scar reductions and improvements in skin quality,” explains Alexiades.
