Identify the exact model
Start with the model printed on the device and its supplied documentation. Our featured listing is the Dr. Pen A6s. Similar names or similar-looking cartridges are not enough to establish a match.
The manufacturer describes the A6S as using a three-slot cartridge locking structure and instructs users to use compatible accessories. Confirm the complete model designation on replacement packaging.
Separate the purchase options
The PepsPlanit listing offers Pen, Pen + cartridge, and Cartridges options. These are separate purchase choices. A cartridge-only price is not the price of the complete device.
Before ordering replacements, confirm the cartridge model, configuration, and quantity supplied. The option name “Cartridges” alone does not specify those details. Contact us if the listing does not resolve your question.
Confirm the replacement, not just the appearance
- Match the full device model to the stated cartridge compatibility.
- Check the connector specification against the supplied manual.
- Confirm the configuration and pack quantity with the seller.
- Check authenticity and packaging rather than relying on color alone.
Dr. Pen has published updates to M8 and A6S cartridge appearance and packaging. This is another reason to use model information and documentation, rather than judging by an older photograph.
We do not assume that A6S, A6, M8, or other models share interchangeable cartridges.
Keep compatibility separate from treatment advice
A matching connector does not determine whether a procedure is appropriate for someone. The FDA recommends consulting a provider trained in microneedling and using a new needle cartridge for each patient and each treatment session. Cleaning a used needle cartridge does not make reuse safe.
This purchasing guide does not prescribe needle depth, treatment frequency, or products to apply during a procedure.
