Dr. Pen M8 vs M8S: Specs, Cartridges and Fakes (2026)

Built from Dr. Pen’s own spec pages (drpen.com and us.drpen.co), the FDA 510(k) database, the American Academy of Dermatology and Setterfield’s Concise Guide to Dermal Needling (3rd ed.), our protocol reference. We haven’t tested these pens hands-on. This is a spec and evidence guide. Last updated: November 2026.

The Dr. Pen M8 is the pen most people start with for at-home microneedling. It’s also the most confusing one to buy. There’s the M8, the M8S and now the M8 Max. There are two official Dr. Pen websites and a pile of look-alike stores. And the Amazon versions don’t match the specs on Dr. Pen’s own store. This guide sorts it out using Dr. Pen’s own pages, not seller copy.

Dr. Pen M8 vs M8S vs M8 Max: which is which?

All three Dr. Pen M8 models are battery microneedling pens with a 0 to 2.5 mm depth dial and swap-in needle cartridges. They differ in motor, battery, charging and which cartridges they take.

• Dr. Pen M8 (Ultima M8). The original. Dr. Pen lists 6 speeds, up to 15,000 RPM, wired or wireless use and a 4-hour battery. Its cartridges are sold as “M8 PowerDerm” on Dr. Pen US.
• Dr. Pen M8S. The update. Up to 16,000 RPM, a 380 mAh battery that lasts 2 to 3 hours, Type-C charging, and its own cartridges with a three-snap fit, per the M8S product page.
• Dr. Pen M8 Max. The newest. 6 speeds, 7,000 to 12,000 RPM, a 500 mAh battery, preset 15, 20 or 25 minute timers, a stand that pauses the pen when you set it down, and chip-based cartridge recognition, per drpen.com and Dr. Pen US.

Don’t read the lower RPM on the M8 Max as weaker. Faster isn’t automatically better. Dr. Pen’s FDA-cleared A20 runs at only 6,300 to 7,700 RPM. For a wider view across brands, see our microneedling pen comparison.

Dr. Pen M8 vs M8S: the differences that matter

The M8S is the better buy for most people, but the original Dr. Pen M8 still has one real edge. Here’s how they split.

• Cartridges don’t swap. Dr. Pen US says M8 cartridges fit only the M8. The M8S has its own cartridge line. Buy cartridges for the exact model on your pen.
• More cartridge choice on the M8S. The M8S line adds 18 and 24 pin options. The M8 line has 11, 16 and 36 pin plus nano.
• Battery goes to the M8. Dr. Pen lists 4 hours for the M8 and 2 to 3 hours for the M8S. Both are plenty for one face session.
• Charging. The M8S charges by Type-C. The M8 page lists a USB charger cable and adapter.
• Speed. 15,000 vs 16,000 RPM. That gap is too small to matter day to day.

Both come with 2 nano cartridges only. Plan on buying needle cartridges separately, and see our at-home microneedling guide for what else a first kit needs. Before your first session, read how to prepare for microneedling.

Dr. Pen M8 Max: what’s new, and the catch

The Dr. Pen M8 Max is the first M8 with a timer and a smart stand. You pick a 15, 20 or 25 minute session on the screen. Set the pen on its stand and it pauses. Pick it up and it resumes. The screen shows speed, battery, timer and cartridge status.

The catch is the cartridges. Dr. Pen says the M8 Max’s recognition system “detects compatible original cartridges.” Plan on buying Dr. Pen’s M8 Max cartridges, not cheap compatibles. Dr. Pen US lists 18 pin, 42 pin and nano round packs. We also didn’t find a Dr. Pen M8 Max listing on Amazon in November 2026. Dr. Pen US calls it “shop only at Dr. Pen USA.”

Is the M8 Max worth it? Only if the timer and pause stand matter to you. At $319 on Dr. Pen US, it costs the same as the A11 and more than the M8 ($199). It isn’t FDA-cleared either.

How the Dr. Pen M8 compares to the A11, A10, A6S and A20

Dr. Pen A11

The Dr. Pen A11 has a 700 mAh battery and a charging base. That compares with 380 mAh on the M8S and 500 mAh on the M8 Max. Outside the A20, it takes the widest cartridge range in the table. But drpen.com labels the A11 “Professional Use Only” and “not intended for personal, home, or medical use.” Dr. Pen US still sells it to anyone at $319. For home use, an M8 or M8S matches what the brand itself says.

Dr. Pen A10

The Dr. Pen A10 is a wireless, 5-speed pen with Type-C charging. drpen.com lists it under home use. Dr. Pen US doesn’t sell it, and drpen.com doesn’t publish its depth or RPM. Without those numbers, we can’t compare it fairly to the M8.

Dr. Pen A6S

The Dr. Pen A6S is the only one here with two swappable batteries. It also runs off a plug-in cord. Dr. Pen lists 16,000 to 18,000 RPM, the fastest in this group. It sells for $249 on Dr. Pen US, more than the M8. Dr. Pen US sells separate A6S cartridge packs for it.

Dr. Pen A20

The Dr. Pen A20 is the one Dr. Pen pen the FDA has cleared. It’s a prescription device for professionals, with 9 depth settings from 0 to 2.0 mm. It’s cleared for facial acne scars. If you see an esthetician or med spa using a Dr. Pen, ask if it’s the A20. Rules on who can do microneedling vary by state. Practitioners can find our microneedling consent form in the forms suite. Our SkinPen guide covers the other FDA-cleared pens, and our provider directory lists top-rated clinics by city.

Is the Dr. Pen M8 FDA-cleared?

No. The Dr. Pen M8, M8S and M8 Max are not FDA-cleared. We searched the FDA 510(k) database for every clearance held by Guangzhou Ekai Electronic Technology. That’s the company that says it owns the Dr. Pen trademark. There’s one clearance: K230420, the “Dr. pen Microneedling System,” dated August 11, 2023. It’s a prescription device for facial acne scars in adults 22 and older. Of the Dr. Pen US pages we checked, only the A20 lists “FDA 510(k)” certification.

The M8 and M8S pages on Dr. Pen US say the pen “may not have been evaluated by the Food and Drug Administration.” That fits the FDA’s rules. The FDA says microneedling products that don’t reach the living layers of skin, and only claim to exfoliate or improve how skin looks, generally aren’t medical devices. Go deeper, or claim to treat scars, and it can count as one.

Dr. Pen M8 on Amazon vs Dr. Pen US: not the same spec

This is the part most reviews miss. The Dr. Pen M8S sold by the Dr.pen Amazon store page on Amazon is titled “Microneedling Pen M8S 0.26mm Needle Length for Home Use.” Its listing says it’s “for cosmetic purposes only.” The Dr.pen-branded M8 cartridges on Amazon are 0.25 mm.

Dr. Pen US sells the same model names with a 0 to 2.5 mm dial. But its disclaimer page says its needle cartridges are “Rx-only.” It sells them only to licensed healthcare professionals and checks the license before shipping. Nano cartridges are the ones it sells to consumers.

So in practice, a US home buyer ends up with a surface-level setup either way. That’s not a bad thing. 0.25 mm is cosmetic depth, the same as a home derma roller, and it’s where we’d point first-timers anyway. Watch for one trap on Amazon, though. Several listings put “Dr Pen” in the title but show a different brand under it. Check the brand line before you buy.

Which Dr. Pen cartridges should you use?

Dr. Pen cartridges come in pin counts from 11 to 42, plus nano. Dr. Pen describes low pin counts as more aggressive and better for small spots. It describes high pin counts as gentler and better for big areas. Here’s how Dr. Pen’s own cartridge guide groups them.

Swipe the table to see all columns →

At home in the US, you’ll mostly use nano cartridges or the 0.25 mm cosmetic packs sold on Amazon. For the face, Dr. Pen’s full-face pick is 16 or 18 pin. For the scalp and body, it’s 36 pin or more. Dr. Pen pitches the full-face cartridges at pores, texture and uneven pigment, and the dense ones at body areas like stretch marks. For depth by concern, use our microneedling depth chart. For scalp work, see microneedling for hair loss. Learn more about surface-only work in our nanoneedling guide.

How to spot fake Dr. Pen cartridges (and pens)

Dr. Pen says fakes are a real problem. In August 2026, drpen.com posted a counterfeit alert about “a significant number of counterfeit Dr. Pen M8 products.” Here’s what it says to check.

On the cartridges

• Blister packs. Genuine Dr. Pen cartridges now come in rigid blister packs. Fakes may use simple paper pouches. One catch: Dr. Pen only switched M8 and A6S cartridges from sterilization pouches to blisters in May 2026. Older genuine stock may still be in pouches. So a pouch alone doesn’t prove a fake.
• Single use. Every genuine cartridge comes sealed and sterile. Dr. Pen US says to throw it out after one session. Sterility is the whole reason to pay for the real thing. Clean the pen body itself after each use, as in our cleaning guide.
• Don’t trust the stamp alone. Setterfield’s Concise Guide to Dermal Needling (3rd ed.) warns that a sealed pack stamped “Sterile EO Gas” is “not necessarily” sterile. The book’s checks: a CE marking, tamper-evident packaging, and the sterilization method printed on the pack. It also says to buy from well-established suppliers with a presence in your region, not from auction sites on price.

On the Dr. Pen M8 pen and box

• Three clean stripes on the front of the pen. Fakes usually have five, unevenly spaced.
• An S-shaped curve from the top to the middle of the body. Fakes tend to be a straight tube.
• A clear serial number on the back of the pen.
• A tight, smooth 3D film around the box, with no peeling or wrinkles.
• An opaque grey velvet pouch, not a see-through bag.
• An anti-counterfeit code printed in blue at the side opening of the box. Fake codes are usually black or black and white, and blurry.

Verify the code

Scratch the security label, then scan the QR code or type the code at drpen.com/verify. Use only that site. Dr. Pen says fake codes can send you to copycat pages. Each code can be checked 3 times, with 24 hours between checks, per Dr. Pen’s verification rules. Dr. Pen US walks through the same steps on its Genuine Dr. Pen page. If it comes back invalid, or it’s already been used up, Dr. Pen says to treat the product as fake. Keep your box and receipt until you’ve checked.

Why one pack costs $17 and another $50

The price gap that worries so many buyers usually isn’t fake vs real. It’s Dr. Pen vs “compatible.” On Dr. Pen US, a 10-pack of M8 16-pin cartridges is $55. A 10-pack of M8S 18-pin cartridges is $59.95. That’s about $5.50 to $6 a cartridge.

On Amazon, most cheap packs are sold by other brands and labeled “for Dr Pen M8” or “compatible with M8S.” In November 2026 they ran about $16 to $37 a pack. Those aren’t Dr. Pen cartridges at all. They’re third-party parts made to fit. Dr. Pen’s device pages say to “only use compatible cartridges and accessories,” and the M8 Max is built to recognize original ones. The Dr.pen Amazon store page’s own M8 packs were $29.98 for 10.

Our rule: if the listing doesn’t show the Dr. Pen brand, your exact model, and a tamper-evident pack with the sterilization method printed on it, skip it. Setterfield’s guide makes the same point. It says not to buy needles on price or discounts, because fakes are getting harder to spot.

Where to buy an authentic Dr. Pen M8

Buying a real Dr. Pen M8 is harder than it should be. Google results for “dr pen m8” and “dr pen m8s” include at least eight other stores with “drpen” in the web address. Several call themselves official or authorized. Here’s what we could confirm.

• drpen.com is the brand site. Its counterfeit statement is signed by Guangzhou Ekai, which says it owns the trademark. It’s the only place Dr. Pen says to verify a product. We found no list of US retailers on it.
• us.drpen.co (drpen.co sends you there) is run by Dr. Pen Australia. Its about page says it’s the only authorized Dr. Pen distributor in Australia, with US warehouses. It’s where we pulled most specs and prices.
• Amazon has Dr.pen and Dr. Pen Amazon store pages. Ekai’s distributor page lists Amazon as a sales channel for its distributors. We couldn’t confirm which Amazon sellers are authorized. So verify the code when it arrives.

We couldn’t confirm any of the other “drpen” stores as authorized from drpen.com. That doesn’t mean they sell fakes. It means you should verify the code before your first session, wherever you buy.

Before you use a Dr. Pen M8: numbing, glide, depth and timing

Numbing cream

At cosmetic depth, you may not need numbing at all. Setterfield’s guide says electric pens are far less painful, and many treatments can now be done without numbing. Dr. Pen US says numbing cream is a good idea for any depth over 0.25 mm. For deeper work, the book calls over-the-counter 5% creams “hopelessly inadequate,” which matches a common complaint about cheap lidocaine. That’s one more reason deeper needling belongs in a clinic. Our numbing cream guide covers how long to wait and why you wipe it off completely before needling.

A sterile glide

You need something on your skin so the Dr. Pen M8 glides. Setterfield’s guide says to use only high molecular weight hyaluronic acid on the day of a session. Our page on microneedling with hyaluronic acid explains why. Dr. Pen suggests HA too. We’d add one rule: make it sterile and single-use, in a glass vial or pre-filled syringe. A big pump bottle from your shelf isn’t sterile. See our sterile hyaluronic acid picks.

Skip the “infusion” cocktails at needle depth. The book warns that pushing ingredients your skin doesn’t make itself into deeper channels can trigger an allergic rash or granulomas, small lumps under the skin. It calls the benefit “negligible.” Save actives for after a cosmetic-depth session, and hold strong ones like retinol after microneedling until your skin settles. The FDA also notes that no microneedling device is approved to deliver cosmetics or drugs into the skin. Our microneedling serums guide has more.

Depth by area

At home, keep a Dr. Pen M8 at cosmetic depth, about 0.2 to 0.3 mm. Setterfield’s guide treats that as the home depth. It says plainly that it does not recommend people treat themselves at 0.5 mm. Even at home depth, go gentler on the forehead and around the eyes, where skin is thinner. Dr. Pen US says 1 to 2.5 mm is the range for acne scarring. That’s professional territory. Every FDA-cleared microneedling pen is a prescription device. Our depth guide has settings by concern. For eye-area work, read our under-eye guide first.

How often

We follow Setterfield’s guide here. At cosmetic depth (about 0.2 to 0.3 mm), it says to needle 2 to 7 times a week, with once daily as the goal. At 0.5 mm and deeper, no more than once a month. The reason: collagenase, an enzyme that breaks down collagen during healing, peaks around day 14. Needling weekly keeps it peaked and works against you. For indented acne scars, the book’s spacing is every 2 months.

Dr. Pen’s own sites give three different answers. Its US FAQ says every 4 to 6 weeks for microneedling and weekly nano needling at 0.25 mm. drpen.com’s FAQ says every 7 to 10 days for beginners. drpen.com’s product page says every 14 days at 0.25 to 0.5 mm. That 14-day gap at 0.5 mm is more often than the book advises. Our full guide on how often you should microneedle lines up every source.

Aftercare

Setterfield’s rule after a needling session: only high molecular weight HA that day, your normal skincare from the next day, and no acids like glycolic for 14 days. Stay out of direct sun as much as you can, and wear sunscreen after microneedling. Our microneedling aftercare guide covers the details, including when to wash your face, when to wear makeup and which moisturizer to use.

At-home safety limits for the Dr. Pen M8

The Dr. Pen M8 is sold for home use, but the safety rules don’t relax at home. Dr. Pen US says its pens are for adults 22 and older. The AAD warns that at-home microneedling can cause infection or scarring if it pierces the skin. It can also spread warts, herpes and other viruses across your skin.

Skip the Dr. Pen M8, or see a professional first, if any of these apply. This list comes from the FDA’s microneedling page.

• You’re pregnant or breastfeeding.
• You have active acne, a rash, a skin infection or a cold sore outbreak.
• You’ve taken isotretinoin (Accutane) in the past 6 months.
• You form keloid scars, or have eczema, psoriasis, vitiligo or an autoimmune disease.
• You take blood thinners or have a bleeding disorder.
• You’re tanned, or will be in the sun in the next 2 weeks.

If you have darker skin, be extra careful. The FDA warns of a risk of the skin darkening or lightening. Check your Fitzpatrick skin type first. If you’re treating melasma, see a professional.

One more thing. drpen.com’s FAQ says to replace cartridges “after every 3 to 5 uses.” Ignore it. Dr. Pen US and the FDA both say one cartridge per session. The FDA calls reuse unsafe “even if the cartridge is cleaned.” If your skin looks rough a few days later, read why skin can look worse after microneedling and our breakout guide. Some flaking is normal, as our guides on peeling after microneedling and microneedling recovery explain.

Our take: which Dr. Pen M8 to buy

Most at-home buyers should get the Dr. Pen M8S. Cleveland Clinic notes that most people need several microneedling treatments over months, so pick a pen you’ll keep using. It has the widest cartridge range of the three M8 models and Type-C charging. On Amazon, it’s sold as a 0.26 mm cosmetic pen, which is the right depth to learn on. Pick the original Dr. Pen M8 if you want the longest listed battery life. Pick the M8 Max only for the timer and stand. If you want deeper results for scars, a clinic is the better spend. See what microneedling costs and weigh the pros and cons of microneedling first.
