Dr Pen M8 and Dr Pen M8S names are close enough to cause confusion, but you should not treat their cartridges as automatically interchangeable. Before ordering replacements, confirm the device model and buy from the matching cartridge family.
If you already know your model, go directly to M8 cartridges or M8S cartridges. If you are still comparing, use the guide below.
M8S vs M8 cartridge compatibility
The safest rule is simple: buy M8 cartridges for M8 devices and M8S cartridges for M8S devices. Some listings online use loose wording, but small connector differences can be enough to cause a poor fit, loose lock, or cartridge that will not click in.
| Question | M8 | M8S |
|---|---|---|
| Best collection to start with | M8 cartridges | M8S cartridges |
| Common replacement types | 11 pin, 16 pin, nano, combo packs | 12, 18, 24, 36, 42 pin, round nano, square nano, combo packs |
| Biggest buying risk | Ordering M8S tips by mistake | Ordering M8 tips by mistake |
| What to check first | Device label and old cartridge connector | Device label and old cartridge connector |
How to tell which model you have
Look for the model name on the device body, original box, order history, or manual. If you still have an old cartridge that fit correctly, compare the connector shape and locking tabs. The cartridge family should match the model name, not just the general “Dr Pen” phrase in a product title.
M8 cartridge options
M8 users often choose between standard pin cartridges, nano cartridges, and combo packs. Popular starting points include:
- 11 Pin Cartridges for M8
- 16 Pin Replacement Cartridges for M8
- Nano Pin Cartridges for M8
- Dr Pen M8 Face Combo Cartridges
M8S cartridge options
M8S has a broader set of common pin count and nano choices. Popular starting points include:
- 12 Pin M8S Cartridges
- 18 Pin M8S Cartridges
- 36 Pin M8S Cartridges
- Round Nano M8S Cartridges
- Square Nano M8S Cartridges
Nano vs pin cartridges
Nano tips are generally chosen for topical finishing and a gentler feel. Standard pin cartridges are chosen when a user needs a traditional microneedling cartridge style. The right choice depends on your device instructions, skin goal, and experience level.
For a deeper breakdown, use the pin count and nano selection guide.
When M8 may be the simpler buying path
If you already own an M8 and mainly need a small set of replacement tips, staying inside the M8 collection can be straightforward. The most common mistake is searching broadly for “Dr Pen M8 cartridges” and landing on M8S listings because the names are similar. Keep the model name in the product title and URL aligned with your device.
M8 buyers often look for a practical mix: one standard pin option, one nano option, and a combo pack if they want several styles in one order.
When M8S may be the broader cartridge path
M8S shoppers often have more visible choices across pin counts and nano shapes. That variety is useful, but it also means you should be more disciplined about filtering. If you need 12 pin M8S cartridges, start from the M8S collection and then choose the 12 pin product. Do not start from a generic 12 pin page unless you double-check model fit.
Compatibility examples
| Search intent | Best page to start | Why |
|---|---|---|
| Dr Pen M8 cartridges | M8 collection | Filters choices to the M8 cartridge family. |
| Dr Pen M8S 36 pin cartridges | 36 Pin M8S product | Matches both model and pin count. |
| M8S round nano cartridges | Round Nano M8S product | Matches model and nano shape. |
Pre-purchase checklist
- Confirm whether the device says M8 or M8S.
- Open the matching model collection first.
- Choose the pin count or nano style second.
- Compare the connector shape with a cartridge that previously fit.
- Do not force a cartridge that does not click in cleanly.
FAQ
Do M8 cartridges fit M8S?
Do not assume they fit. The safest purchase path is to buy from the M8S collection for an M8S device and the M8 collection for an M8 device.
Is M8S newer than M8?
Many shoppers view M8S as a later or different model family, but the important buying detail is not release order. The important detail is matching the cartridge connector to the device you own.
What if my cartridge will not lock?
Stop and inspect the model, connector, and packaging. The fit troubleshooting guide explains the next checks.
Should I switch from M8 to M8S just for cartridges?
Not necessarily. If your current M8 works for your routine, the simpler move is to keep buying the correct M8 cartridges. Consider a device switch only if the device features and cartridge range match your long-term use case.
Are M8 and M8S nano cartridges the same?
Do not assume they are the same. Nano describes the tip style, while M8 or M8S describes the cartridge family and connector fit.
Bottom line: M8 and M8S cartridge names look similar, but matching the exact device family is the best way to avoid fit problems and returns.
