At-home microneedling has quietly gone mainstream, and the category now spans everything from budget replacement cartridges to electric pens that pair rolling and stamping in one device. If you’re building a routine without salon visits, the hardest part is matching a cartridge or pen to the handle you already own (or planning to buy). This shortlist breaks down six well-reviewed options, the handles they fit, and where each one genuinely shines for a home user.
How The Shortlist Stacks Up
AUSGOOD 36Pin Cartridges for Dr Pen A11/M8S
Granatan Skin Roller Cartridges for M8
Hydra Pen H3 Microneedling Pen 0.25mm
FIOSAXE 20PCS 24-Pin Cartridges for Dr Pen A6
PIPM 36pin 0.25mm Cartridges (10-Pack)
Dr.pen Cartridges for M8S, A9, A11
Taking A Closer Look At The Options
If you’re brand new to at-home microneedling and want to start with the gentlest setting, this 15-pack of AUSGOOD cartridges earns the top beginner slot. The 0.25mm needle depth (a “cosmetic-only” length that stays on the surface) is widely considered the easiest entry point for first-timers, and the heads are built to twist-lock onto Dr Pen A11, M8S, A8S, and A9 handles. Compared with the PIPM cartridges we’ll get to later, the AUSGOOD pack ships in a larger quantity, which suits a weekly routine without constant reordering.
You won’t find much hand-holding in the box, so newcomers should read up on sanitizing the cartridge between sessions and replacing it every few uses. For most people easing into the practice, that tradeoff is a fair one.
Useful Highlights
- 0.25mm depth stays in the gentlest cosmetic range, so first sessions rarely leave lasting redness.
- Twist-lock fit on multiple Dr Pen handles means one cartridge pack can travel between devices.
- Fifteen heads cover roughly a month or more of weekly sessions, lowering per-use cost over time.
- 36-pin layout spreads contact across the skin, which suits broader areas like cheeks and forehead.
Things To Consider
- You’ll need to confirm your exact Dr Pen handle model before ordering, since fit is specific.
- Owners commonly report the cartridge needle guards loosen after several uses, so replacement discipline matters.
Made For
First-time at-home users with a compatible Dr Pen handle who want a low-commitment introduction to microneedling.
Consider Something Else When
You already own a Dr Pen A6, in which case the FIOSAXE 24-pin cartridges reviewed further down fit that model more directly.
Granatan’s ten-pack lands as the everyday workhorse for anyone already running an M8-compatible pen. The 36-pin head and 0.30mm length sit a hair deeper than the AUSGOOD set, which experienced home users tend to prefer for face-and-neck sessions. You may find the slightly longer reach helpful for areas where you want a more assertive pass, like the lower cheeks or jawline, while still staying inside the cosmetic range.
Unlike the WPDGAD Hydra Pen, this is purely a replacement cartridge, not a powered device. That keeps the cost straightforward, but it does mean you need the M8 handle to make it useful.
Strong Points
- 0.30mm depth gives a slightly more assertive session without leaving the cosmetic-only range.
- Ten-pack size balances affordability with a usable lifespan for monthly routines.
- M8 fit is direct, with no need for adapters or fiddly locking steps.
Trade Offs
- The 36-pin density isn’t ideal for tight areas like the nose folds.
- Cartridges should be replaced every few sessions for hygiene, and ten heads may run out faster than expected for frequent users.
Right Fit For
Home users with an M8 pen who run steady weekly sessions and want a clean, no-frills refill.
Skip It When
You’d rather have a single electric device that applies serum at the same time, in which case the WPDGAD Hydra Pen H3 is a more compelling setup.
The WPDGAD Hydra Pen H3 is the only all-in-one electric device on this list, and that alone reshapes the routine. It blends a derma roller motion with a derma stamp head, and pairs that with a small reservoir so serum flows out as the needles work. For someone whose main goal is layering a hydrating serum during a session, that’s a meaningful step up from a passive cartridge.
Six speed settings cover everything from delicate under-eye work to firmer passes along the cheeks. The trade-off shows up in cleaning: the liquid pathway adds a step that a simple cartridge doesn’t require.
Advantages To Know
- 2-in-1 design pairs rolling motion with serum delivery, which can save a separate application step.
- Six speed settings span gentle and firmer passes for different zones of the face.
- Anti-leak reservoir design reduces the messy “serum everywhere” risk older infusion pens had.
- 0.25mm tip keeps the depth cosmetic-only, fitting most beginner-to-intermediate routines.
Points To Note
- Flushing the serum chamber between uses takes longer than wiping down a plain cartridge.
- Liquid outflow control is helpful, but you’ll want to test the lowest speed first to learn the flow rate.
Quick Facts
Who Should Grab It
Anyone building a serum-first routine who wants one electric tool that handles both needle motion and product flow.
Another Choice May Suit
If you already own a Dr Pen M8S handle and just need fresh heads, the Granatan M8 cartridges reviewed earlier are a simpler, lower-cost path.
FIOSAXE’s 24-pin pack targets the Dr Pen A6 specifically, a handle that’s a little less common on this list. The 24-pin layout is denser than the 36-pin heads above, which makes it a better fit for narrower zones like the upper lip, around the nose, or the brow area. Twenty heads in the pack plus a small storage case turn this into a tidy travel setup.
For home use, the case doubles as a way to keep used and fresh heads separate. The 0.25mm length keeps things on the gentler end of the spectrum.
Noteworthy Benefits
- 24-pin head works well on smaller zones where a 36-pin feels too wide.
- Twenty-count pack supports months of weekly sessions.
- Included storage case helps separate clean and used heads while traveling.
- Direct fit for Dr Pen A6 handles without adapters.
Room For Improvement
- Pin count is lower, so each pass covers less area on broader zones.
- A6-specific fit means shoppers with other Dr Pen handles will need a different pack.
Built With In Mind
Dr Pen A6 owners who want a travel-friendly refill and tighter control on small facial areas.
Reach For A Different Pick When
You use a Dr Pen A11 or M8S, in which case the Dr.pen-branded cartridge pack covered later is the more compatible option.
PIPM’s screw-slot cartridges slot into a narrower range of pens, including the PIPM Y81, A690, and A703. That makes fit-checking essential before you order, since the locking style differs from the twist-lock heads on the rest of the list. Once matched, the 36-pin layout and 0.25mm depth give you a familiar, gentle session at a practical price point for routine replacement.
For anyone committed to a single-cartridge-per-session rule, ten heads cover roughly ten sessions, which most people can stretch across several months.
A Strong Showing
- 0.25mm depth keeps sessions gentle for users still dialing in their routine.
- Single-use-per-session guidance is clearly communicated, helping newcomers stay hygienic.
- Affordable ten-pack works for casual, low-frequency routines.
Small Caveats
- Screw-slot fit means it won’t work with most Dr Pen handles out of the box.
- Replace-each-session guidance means the pack empties faster than higher-count alternatives.
Whose Shelf It Belongs On
PIPM handle owners who want a direct, no-adapter replacement and stick to single-use cartridge hygiene.
A Better Fit Elsewhere
Dr Pen M8S users are better served by the Granatan cartridges reviewed earlier, which match that handle without an adapter.
Closing out the list, this Dr.pen-branded pack is the most direct replacement option for anyone running an M8S, A9, or A11 handle. The heads are designed by the same brand that builds the pens, which removes the compatibility guesswork that comes with third-party packs. For cosmetic-only home use, that’s a meaningful convenience if you want to avoid the “does this actually fit?” forum deep-dive.
The honest read is that this pack trades the larger count of the AUSGOOD set for a tighter compatibility list. If your handle is on the list, the simpler buying decision is usually worth it.
The Practical Payoff
- Same-brand design means fewer compatibility surprises on supported Dr Pen handles.
- Cosmetic-only focus keeps sessions within the gentlest depth range for home use.
- Direct replacement heads suit existing handle owners who already know their routine.
Factors To Consider
- Compatibility is narrower than the AUSGOOD pack, so verify your handle model first.
- Pack size is more modest, so heavy weekly users may reorder sooner than with 15- or 20-count options.
Perfect Match For
Anyone already using a Dr Pen M8S, A9, or A11 who wants the simplest possible refill path.
Look Elsewhere When
You own a Dr Pen A6, since the FIOSAXE 24-pin pack covered above is the better-matched refill for that handle.
Choosing The Right Fit For Your Routine
A few attributes do most of the work in this category, and understanding them upfront makes the rest of the decision easier. Needle depth is the first gate: 0.25mm and 0.30mm cartridges sit in the cosmetic-only range, which is what most home users should stick with. Anything longer than that crosses into territory better suited to professional settings, and isn’t covered on this list for that reason.
Handle Compatibility Is Non-Negotiable
Microneedling pen cartridges are not universal. Dr Pen handles alone come in A6, A8S, A9, A11, and M8S variants, each with its own locking mechanism. PIPM handles use a screw-slot fit. Before picking a cartridge, confirm the exact model printed on your pen, then cross-check it against the cartridge listing. Buying the wrong fit is the most common misstep in this category.
Pin Count Changes The Feel
Pin count affects how a head feels on the skin. A 24-pin head sits denser and works well on smaller zones, while a 36-pin head spreads contact across broader areas. Neither is universally better; it depends on which parts of your face you focus on most. If you alternate between cheeks and the under-eye area, owning one of each can be useful.
Decide Between Cartridges Or An Electric Pen
Five picks here are passive cartridges that fit existing handles, and one (the Hydra Pen H3) is an electric device. The cartridge route keeps cost lower and storage minimal, while an electric pen adds serum infusion and adjustable speed. Your existing handle (or willingness to buy one) usually answers this question for you.
Key Considerations Across These Picks
Pitfalls Shoppers Hit
The single biggest mistake is ordering by pin count or depth without checking the locking style. Dr Pen, PIPM, and other brand ecosystems all use slightly different attachment mechanisms, and a 36-pin head from one line will not snap onto another. Reading the model list on the cartridge page and matching it to the engraving on your pen takes thirty seconds and saves a return.
Where The Extra Money Goes
Higher-tier picks in this category tend to bundle storage cases, larger pack counts, or electric-pen features like speed control and serum infusion. None of that changes the underlying cosmetic-only depth range, so the upgrade is mostly about convenience and routine polish rather than results. For most home users, a well-matched mid-pack cartridge covers everything the routine actually needs.
Frequently Asked Questions
How often should I replace a microneedling pen cartridge? Most sources recommend a fresh cartridge every few sessions, or even every session, since the tips dull with use. Single-use is the safest rule for hygiene, especially on shared devices.
Are 0.25mm and 0.30mm needles safe for home use? Yes, both lengths stay in the cosmetic-only range and are widely used in home routines. Longer needles belong in professional settings and aren’t covered on this list.
Can I share one pen between cartridges and serum applicators? Only if the device supports both. Standard cartridges swap onto a pen handle, while serum applicators like the Hydra Pen H3 are separate electric devices that combine both functions.
Do I need to sanitize the cartridge between uses? Light cleaning with rubbing alcohol before and after each session is the common practice. A fresh cartridge every few sessions still matters even with cleaning.
Will these cartridges fit any microneedling pen? No. Compatibility is brand- and model-specific, so always confirm your exact handle model before ordering. Dr Pen A6, A11, M8S, A8S, and A9 each use different fittings.
The Takeaway
Pick the cartridge that matches your exact handle, and lean toward the gentler 0.25mm depth if you’re still building a routine. The Hydra Pen H3 is the right call when serum infusion matters more than cartridge simplicity, while the larger-pack options suit steady weekly users who reorder less often. Match the tool to your handle and your habit, and the rest of the routine tends to fall into place.
