Is at-home microneedling as good as professional?
Last updated:
No. The microneedling devices FDA has authorized for acne scars and wrinkles are used by trained providers, and FDA has authorized none for over-the-counter sale. Rollers sold for home use generally have short needles meant for exfoliation and a smoother look, and Health Canada has authorized no microneedling device for home use, citing higher risks of misuse, contamination and infection.
What is the difference between at-home and professional microneedling?
The difference is how far the needles go2. Some microneedling products have needles so short that they only touch the topmost layer of skin, which is mainly dry, dead cells, while others have longer needles that reach deeper layers with living cells, nerves and blood vessels2. FDA's guidance treats needle length, needle sharpness and control over penetration depth as evidence of whether a product is a medical device3.
In the United States, a microneedling device for aesthetic use is a class II medical device subject to special controls4. Most of the devices FDA has cleared are pen-shaped and motorized, and FDA has not authorized any microneedling medical device for over-the-counter sale2. A dermal roller with short, blunt needles that claims only to remove dead skin and smooth and brighten the skin is generally not a medical device, and such products are more commonly sold for use at home2.
| Question | Products sold for home use | Professional devices |
|---|---|---|
| Needle reach | Short, blunt needles that act on the dead outer layer2,3 | Longer needles that reach living layers; clinical devices use longer needles2,6 |
| Typical format | Manual roller2,7 | Mostly motorized pens; some let the practitioner set depth and speed1,2 |
| US status | Generally not a medical device when claims are limited to exfoliation and appearance3 | Class II medical device; none authorized for over-the-counter sale2,4 |
| Canadian status | No microneedling device authorized for at-home use5 | Authorized for professional use only5 |
| Authorized results | Claims limited to exfoliation, a smoother feel and a luminous look3 | Improved appearance of facial acne scars, facial wrinkles and abdominal scars, age 22 or older1 |
In North America, searches about home microneedling peak in March and are lowest in September; FDA lists a tan, or sun exposure planned in the two weeks after the procedure, as a reason microneedling may not be suitable, which matters more as spring sun increases1. In the Southern Hemisphere, the same spring rise falls around September to November.
Does at-home microneedling work?
Home rollers can address mild concerns, but a 2024 review describes their limited needle depth as making them less effective than professional devices7. Automated pens reach deeper and target scar tissue more precisely than manual rollers7.
The evidence behind microneedling results comes from professional devices1,6. FDA authorization for acne scars, wrinkles and abdominal scars rests on data FDA reviewed for specific devices, and none of them is authorized for over-the-counter sale1,2. A systematic review of 51 studies covering 1,029 patients drew its findings from clinical trials, retrospective studies and case reports of roller, stamp, pen and radiofrequency procedures6.
Even with a professional device, one session may not be enough2. FDA notes that more than one procedure may be needed and that any improvement may be temporary, with maintenance procedures over time2.
What are the risks of microneedling at home?
Health Canada states that no microneedling device has been authorized for at-home use, where there are higher health risks from inappropriate use, contamination and infection5. Its 2021 advisory warned that unlicensed microneedling pens and cartridges were being sold online, in salons and spas and through beauty academies, often advertised for use at home5.
Infection is the risk that home use magnifies5. A systematic review of adverse effects reports a woman who used a home roller on acne-like spots and spread varicella from her chest to her face, and its authors point to the potential for self-inoculation with self-administered treatment6. FDA advises cleaning a home microneedling product between uses as the manufacturer directs, and never sharing it, to avoid infection or spreading disease2.
In clinics, FDA tells providers not to reuse a needle cartridge or use one on more than one patient, because it could transfer infectious agents1. Common side effects of any microneedling device include dryness, tightness, redness, itching, peeling, bruising, bleeding and crusting1.
Can you use a serum with at-home microneedling?
Not as a way to push it into the skin1. FDA states that microneedling devices are not approved for delivering cosmetics, topical medications, vitamin solutions, drugs or blood products such as platelet-rich plasma into the skin1. The US device classification excludes devices intended to deliver topical products such as cosmetics, drugs or biologics through the skin4.
Topicals used with needling have caused reactions6. Three patients developed a delayed granulomatous reaction with fever, malaise and joint pain after microneedling with topical pretreatment, two of them linked to a vitamin C serum, and the review notes that the topicals were not necessarily intended for use with microneedling or for delivery into the dermis6.
After a session, FDA says skin may be more sensitive to the sun and to products containing retinol, glycolic acid, menthol, capsaicin or alcohol2. FDA has not cleared any microneedling device for use with another product, so the safety of combining them has not been reviewed2.
What is the difference between a dermaroller and a microneedling pen?
A dermaroller is one form of microneedling device, with needles fitted onto a cylinder that is rolled across the skin2. Other formats are flat stamps pressed into the skin and pen-shaped instruments with needles arranged on the tip2.
Manual devices such as rollers and stamps have needles that always project from the surface and enter the skin as the device is rolled or stamped1. Pens use a motor to move the needles in and out, and in some motorized devices the practitioner can adjust the depth and speed of penetration1. A 2017 review describes the pen as delivering stamp-like motions across the skin, and notes that medical roller models come in more than one needle length8.
Who should not microneedle, at home or in a clinic?
FDA lists conditions in which the procedure may not be suitable, including:
- Bleeding or clotting disorders, or blood thinners such as warfarin, heparin or low dose aspirin1
- A weakened immune system or uncontrolled diabetes1
- Active bacterial, viral or fungal skin infection, an active facial rash or a cold sore outbreak1
- Eczema, psoriasis or vitiligo, now or in the past1
- Isotretinoin now or within the past 6 months1
- Keloid scars, warts, birthmarks or moles in the area1
- Pregnancy or breastfeeding1
- A tan, or sun exposure planned in the two weeks after the procedure1
Key takeaways
- FDA has authorized no microneedling medical device for over-the-counter sale, and Health Canada none for home use.

- A 2024 review rates home rollers as less effective than professional devices because of their limited needle depth.
- Microneedling devices are not approved to deliver serums or other topicals into the skin, and reactions have been reported.
- Clean any home device as directed and never share it; infection is the main home risk.

Frequently asked questions
What needle length counts as at-home microneedling?
FDA's guidance does not set a single cutoff; it looks at needle length and arrangement, sharpness, and control over depth to decide whether a product penetrates living skin and is a device3. Products designed so they do not reach living layers, because of needle length, blunt tips or densely packed needles, are generally not devices when they claim only exfoliation and a smoother look3.
Can you microneedle at home if you have acne?
Is a home microneedling pen the same as the one in a clinic?
Not necessarily. In Canada, microneedling pens and cartridges need a medical device license, and Health Canada advises checking its online list of licensed medical devices before buying5. FDA urges providers to confirm a device appears in its De Novo or 510(k) databases, because several devices on the market are not legally marketed1.
