“When used on the face, dermarollers pierce the stratum corneum layer of the epidermis, 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.

Translation? When your skin kicks into recovery mode, even if it’s from a microtrauma, your collagen and elastin production are triggered, thus contributing to tighter, more supple facial skin. This, in turn, may result in the easing of fine lines and wrinkles, Henry notes.

“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). 

For hair growth purposes, dermarolling can also be used along with hair growth serums to boost their efficacy—more on scalp treatment to follow.  

“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 investing in an at-home tool? Well, it all depends on how committed 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 damaging your skin, triggering 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 remiss 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 appearance 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.

However, if you still want to experiment with dermarolling and give the DIY method your best shot before investing in a professional microneedling treatment, that’s fair—but still, proceed with caution.

• You have to do it on freshly clean skin, with no blemishes or wounds.
• You must clean the roller before and after use.
• Don’t store it in a place where it can get dirty and potentially transfer bacteria (i.e., on your bathroom sink).
• Be careful with the products you use after (more on that to come). 
• Be mindful of how often you do it.
• Don’t go over the same area too many times. 

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.

Avoid any irritating cleansers—stay away from chemical exfoliants like AHAs and BHAs, benzoyl peroxide, and harsh physical scrubs before you use your dermaroller.

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.

“Finally, you can pat the tool dry using a clean washcloth. Repeat this same step once you finish working on the skin,” she finishes. This will ensure the tool is free of bacteria and any buildup.

Lightly roll the dermaroller over your skin, without adding any pressure. There’s no need to press the tool into the skin, as the needles will penetrate on their own and extra force may lead to irritation.

If it’s your 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.

“Thicker areas of the face can benefit from slightly higher frequencies of dermarolling, while the thinner more sensitive areas can become more easily irritated,” Henry notes. So stick to a once-over on areas like the forehead and chin. For the cheeks, you may be able to go over the area twice.

Cleanse your tool again.

Follow up with hydrating, soothing topicals. 

“As dermarolling can cause some skin irritation initially, 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.

A few ingredients to add to your post-dermaroller routine include:

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 stimulate 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.

Hydrate the skin afterward, even on areas with facial hair.

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 in tandem 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.

And moreover, your dermatologist or aesthetician will let you know if you’re a good candidate for this procedure—as microneedling is not right for everyone. Those with active acne, rosacea, psoriasis, or other inflammatory skin conditions may actually be better off without it—professional-grade treatment or not.

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).
