Do Dermarollers Work? What To Expect, Cautions + How To Know If It's Right For You

Just because you can do something yourself, does that always mean you should? When it comes to skin care, experts say not so much–especially if you're only doing it because it's trendy.

Dermarollers are skin care tools that contain hundreds of tiny needles. These tools are different from those used in professional microneedling treatments, as those put tiny needles straight into the skin (like a stamp), whereas dermarollers literally roll over the skin. Plus, the in-office needles generally penetrate deeper because they use longer, sharper needles.

Many skin care experts like aestheticians and dermatologists, for example, have microneedling tools in-office should their clients want the service, but they don't often have the at-home-style dermarollers.

While traditional microneedling has been used commercially since the '90s, at-home dermarollers have become more popular over the past few years, especially with the rise of beauty TikTok.

"When used on the face, dermarollers pierce the stratum corneum layer of the epidermis (the uppermost layer), creating minute punctures," Henry explains. "This ultimately leads to the triggering of our body's wound-healing process and the release of growth factors that stimulate cell regeneration and the production of collagen and elastin," she continues.

"The dermaroller also creates microchannels that allow for increased product absorption into the skin, making products applied to the face more effective," certified trichologist, celebrity stylist, and founder of scalp-first hair care brand Act+Acre Helen Reavey tells mbg. 

When used in conjunction with healthy skin aging products like face creams, studies have demonstrated the power microneedling has to essentially supercharge the effects of a topical product1—which can be both good and bad (more on that to come). 

"Through the production of these structural skin proteins, dermarollers can help ease the signs of certain skin concerns, such as acne scars," Henry notes. Whether it be indented scars from cystic acne, previously picked-at breakouts, or even stubborn hyperpigmentation, microneedling can help to press restart on the skin post-acne treatment.

It's important to note that professionals most often recommend skipping any active breakouts when dermarolling, as opening the pimple or penetrating the cyst can lead to pain, infection, and redness. 

So all of those benefits sound great, but is it worth spending money on an at-home tool? Well, it all depends on how loyal you are to the process and what your goals are, as this is nowhere near a one-and-done deal—there are in-depth cautions, techniques, and cleaning protocols you have to follow.

And if you don't, you may risk harming your skin, causing infection, etc. Plus, "The tools used by dermatologists are often electric-operated and can penetrate deeper, stimulating more robust rejuvenation," Henry says.

We'd be careless to not mention the fact that there are plenty of other at-home steps you can take to tend to light acne scars and hyperpigmentation, reduce the look of fine lines and wrinkles, and help your products penetrate deeper into the skin, sans tiny rolling needles.

Also, deeper acne scars, often referred to as "ice pick," or "indented," scars, are extremely difficult to treat at home, even with a dermaroller, as the depth of professional needles generally leads to the best results—and it often takes more than one session.

Don't ever use your dermaroller on skin that hasn't been properly cleansed. You can choose to do a double-cleanse if you're wearing makeup or SPF, or stick with a single gentle cleanser. Gently dab your face with a clean rag afterward to make sure all of your products have been washed off.

This part is nonnegotiable (and you'll do it again after it touches the skin). "The best way to clean the tool is to first rinse it under lukewarm water, and then wipe or soak it for about five to 10 minutes in 70%+ ethyl or isopropyl alcohol," Henry explains.

Lightly roll the dermaroller over your skin, without adding any pressure. You don't have to press the tool into the skin, as the needles will penetrate on their own and extra force may lead to irritation.

For the first few times dermarolling, go over each area of the face just once. "Dermarollers can be applied two to four times to the same area depending on one's sensitivity," Henry says—but you'll want to start out slow and see what your skin can tolerate.

"As dermarolling can cause some skin irritation at first, it's optimal to use skin care products that add extra hydration and nourishment," Henry says. Stick with bland moisturizers and hydrating serums, Henry notes, like the Kiehl's Ultra Facial Cream or Pipette Baby Balm.

Avoid AHAs (lactic acid, glycolic acid, etc.), BHAs (salicylic acid), retinol of any form, and vitamin C. While these are great ingredients to use in your overarching routine, they're not formulated to be used on broken skin with microtraumas.

Stick with a gentle, simple routine for at least a few days, or a week if you have sensitive skin.

As mentioned above, microneedling has been used as a treatment for alopecia, or hair loss. While dermarollers can be used to promote hair growth, you'll have to be as cautious when it comes to protocol.

"The needles work to create microchannels on the scalp that help to increase blood flow to the hair follicle and release growth factors," Reavey says. "It's an amazing tool to implement for accelerated hair growth rates," she continues.

Microneedling and dermarolling on the scalp help to increase the absorption and penetration of treatments within the skin and prevent thinning and balding caused by temporary hair loss, Reavey says.

Your scalp may be a bit less sensitive than your face, too. "The skin is a bit thicker and has a greater abundance of sebaceous glands, which produce sebum to protect your hair," Reavey explains.

If you're going to use a dermaroller on your scalp, be sure to do so on freshly cleansed hair and follow up with a hydrating scalp serum—may we suggest the Act+Acre Dermaroller Growth System Set that comes with both?

You can also visit a trichologist or dermatologist for microneedling on the scalp if you'd rather not go through the process at home.

As you now know, circulation is key when it comes to triggering increased growth and both preventing and treating hair loss—and dermarolling on the scalp is just one way to do so. You can also practice less invasive methods such as scalp massage, scalp and hair oiling, and consider hair growth serums and supplements if dermarolling isn't for you.

You can use a dermaroller on the beard to encourage growth as well, Reavey notes. Here's a few specific tips to keep in mind if you plan on using your dermaroller on your beard:

Deeply cleanse your facial hair before, as it easily holds on to bacteria, oils, etc. 

You may need to go over the area more than once, as facial hair can interfere with needle penetration.

As mentioned throughout, professional microneedling treatments are a much safer option than dermarolling at home, and they're going to be more effective in the long run. What's more, plenty of microneedling treatments are used with other tools like LED light therapy, for example.

Plus, the professional tools used often have adjustable needle lengths, meaning you can use shorter needles on areas with thin skin (like the nose, chin, forehead, etc.) and longer ones on thicker areas like the cheeks. This helps to ensure you're never penetrating too deeply.

While it can feel exciting to try out a new-to-you skin care tool that people have raved about on social media or by word-of-mouth, your skin can't always take trend after trend. Your skin is unique, and how you care for it should be as well.

And to that end, plenty of people praise dermarolling because it can cause products to penetrate deeper into the skin. While this is great for those hydrating humectants like hyaluronic acid and aloe vera, it's not entirely necessary when it comes to strong actives like retinoids.

As your derm will tell you—these prescription-grade products and even some OTC retinols and exfoliants generally penetrate the skin just fine on their own. And as long as you clear out dead skin cells via exfoliation, the products will get into the skin as need be. Thus, why you don't need dermarolling to make sure your skin care "works"—high-quality products used in a dedicated routine will do that on their own.

So if you want to use dermarolling to ease acne scars, encourage hair growth, or contribute to skin longevity—do it, but with caution. However, if you're just doing it to do it, without proper technique and any significant reason, you may want to ask yourself if you're more motivated by the benefits or the fact that it's trending (and yes, we've all been there).

While you can get an at-home dermaroller for DIY-style microneedling, it won't produce the same dramatic effects. In-office tools have longer, sharper needles and penetrate the skin differently, making them more effective.
