Frequently Asked Questions

Are these cartridges compatible with all Dr.pen models?

These cartridges are specifically designed for Dr.pen M8S, A8S, A9, and A11 handpieces. They are not compatible with other Dr.pen models such as M7, A6, or A7. Please confirm your device model before ordering.

How many times can I use one cartridge?

These are single-use, sterile cartridges. Each cartridge must be discarded after one treatment session. Reusing cartridges compromises sterility, increases infection risk, and causes needle blunting that reduces treatment effectiveness.

Which pin type should I choose for my treatment?

Use 12PIN–24PIN for general skin rejuvenation, fine lines, and texture improvement. Choose 36PIN or 42PIN for scar revision, stretch marks, or deeper treatments. Nano-S is ideal for sensitive areas and serum infusion; Nano-Round suits scalp treatments and broad surface coverage.

What is the anti-backflow feature and why does it matter?

The anti-backflow mechanism uses a one-way valve to prevent serum, blood, or bodily fluids from entering the handpiece during treatment. This protects the device from internal contamination and is essential for maintaining hygiene standards in professional clinic settings.

What depth setting should I use?

Start at 0.25mm for sensitive or thin skin and gradually increase based on treatment goals. Face rejuvenation typically uses 0.25–0.5mm; scar and stretch mark protocols use 1.0–1.5mm. Always follow professional guidelines and client tolerance.

Are these cartridges sold individually or in packs?

Each listing is for one individual cartridge. Select your preferred pin type at checkout. Bulk pricing is available — contact us for clinic and studio orders.
