Aiscool Microneedling Pen Cartridges 12-Pack 18‑Pin 0.25mm — Dr Pen M8S/A11/A8S/A9 Compatible, Sterile Single‑Use

Aiscool 12-piece 18‑pin microneedling pen cartridge set provides ready-to-use, 0.25mm sterile tips compatible with Dr Pen M8S, A11, A8S and A9 for gentle at‑home exfoliation and product absorption support.

These replacement cartridges are designed for users who want a consistent, low-depth microneedling option that fits specific Dr Pen models. Each pack contains twelve single-use heads with 18 fine needles at 0.25mm length—an entry-level depth intended for surface-level exfoliation and improving topical product spread. The cartridges arrive sterile, preassembled, and ready to snap onto your compatible pen, simplifying routine upkeep and ensuring a hygienic changeout each time.

How do these 0.25mm cartridges work for at‑home routines?

The 0.25mm needle length is intended for superficial skin resurfacing and facilitating better topical absorption during at‑home care. They create micro-channels in the outermost skin layer without deep penetration, helping serums and moisturizers distribute more evenly.

• Needle length: 0.25mm for surface-level effect
• 18 stainless micro-needles for even, consistent coverage
• Single-use, sterile cartridges reduce contamination risk
• Snap-fit design for quick attachment to compatible pens

Which Dr Pen models are these cartridges compatible with?

These cartridges are engineered specifically for Dr Pen M8S, A11, A8S and A9. They will not fit other brands or older/other Dr Pen models not listed, so confirming your device model before purchase is essential to ensure proper fit and function.

• Compatible models: Dr Pen M8S, A11, A8S, A9
• Not compatible with non-listed or older Dr Pen versions
• Confirm your pen model number on the device housing before ordering
• Each cartridge is preassembled for a secure connection

What are the safety and hygiene features of these cartridges?

Each cartridge is sterilized and designed for one-time use to minimize infection risk and maintain needle sharpness. Using a fresh head each session preserves performance and hygiene compared with reusing or attempting to sterilize disposable tips.

• Sterile, single-use packaging for each cartridge
• Replace after every session to avoid cross-contamination
• Dispose according to local regulations for sharps or plastic medical waste
• Handle only by the plastic base to keep needles sterile until use

How should I incorporate these cartridges into my skincare plan?

Use the 0.25mm cartridges as part of a gentle at‑home regimen focused on exfoliation and improving topical product penetration. Limit sessions to manufacturer guidance, and pair treatments with soothing, hydrating serums after use. Avoid aggressive techniques or excessive frequency.

• Apply topical serums after treatment for better absorption
• Follow recommended intervals between sessions for skin recovery
• Use sunscreen and avoid harsh actives immediately after treatment
• Consult device instructions for speed and technique settings
