Derma Rollers and Home Microneedling: What You Can Expect and What to Skip

In-office microneedling uses fine needles to make tiny controlled injuries in the skin, which prompts it to make new collagen. Home derma rollers, stamps and pens are sold with the same before-and-after promises at a fraction of the price. Here is how the two compare, and the risks that come with pushing a home device harder.

They’re not the same treatment

The American Academy of Dermatology (AAD)¹ says products sold for home microneedling, and microneedling in non-medical spas, aren’t meant to puncture the skin.¹

The FDA² draws the same line. Its guidance separates products that only reach the outer dead layer of skin, the stratum corneum, from products meant to reach the living layers below it. Products in the second group are regulated as medical devices.² Rollers, stamps and pens are all named in that guidance.²

	In-office microneedling	Home rollers and stamps
Goal	Controlled punctures into living skin to prompt collagen1	Not meant to puncture the skin1
Typical plan for acne scars	3 to 5 treatments, 2 to 4 weeks apart1	No equivalent plan
Results	Studies found acne scars faded 50% to 70%; full results take several months1	No comparable evidence cited by the AAD

The risks of pressing harder

It’s tempting to press harder when a gentle roll doesn’t seem to do much. The AAD warns that:¹

• Pressing too hard can damage your skin and cause scarring or changes in skin color or texture.
• Overuse can irritate the skin and make the concern you’re treating more noticeable.
• Home microneedling can spread warts, cold sores and other viruses across the skin.

The FDA² lists cross-contamination and infection, damage to nerves and blood vessels, scarring and color changes among the risks of devices that puncture living skin.²

Who should skip microneedling

The AAD advises avoiding microneedling if you:¹

• Heal slowly or poorly
• Have or have had a keloid, a raised, thick scar
• Have a weakened immune system from a condition or medicine
• Are being treated for skin cancer in the area
• Are having radiation treatment

Also skip it over active cold sores, warts, acne flares or broken skin, given the AAD’s warning about spreading viruses.¹

If you still want a home roller

• Choose one sold for surface use, and follow the instructions on pressure and how often to use it.
• Keep it to yourself. Never share it.
• Clean it exactly as the maker directs, and replace it as instructed.
• Stop if your skin bleeds, stings for long, or looks irritated.

If you want results like the photos

Ask a board-certified dermatologist whether in-office microneedling, a laser, a peel or a prescription treatment fits your concern, and what the full course would cost.

Try: “I’ve been looking at a derma roller for fine lines and old acne scars. What would you recommend for my skin, and how many treatments would it take?”
