42-Pin Microneedle Cartridges with Integrated Smart Chip for Dr Pen M9

Designed for advanced skin refinement, the Dr. Pen M9 42-Pin Microneedle Cartridges with Integrated Smart Chip (5 Pack) deliver high-density microneedling performance for deep resurfacing and efficient coverage across larger treatment areas. The dense 42-pin configuration supports intensive micro-channel creation, making it a strong choice for improving the appearance of mild acne scarring, stretch marks, visible spots and wrinkles, while supporting a firmer, smoother-looking finish.

For Larger or Sensitive Areas
Higher pin cartridges are best suited for larger treatment areas or more delicate skin, such as the scalp, neck, décolletage, and upper or inner thighs. Because the pins are more densely distributed, the treatment is generally gentler but covers a wider area efficiently. These cartridges may require multiple sessions to achieve optimal results.

Here is the cartridge selection guide for more information.

How to Use

Please note: Dr. Pen cartridges arrive in individually sealed, sterile pouches, sterilised with ethylene oxide gas and UV light during packaging. Secondary sterilisation with isopropyl alcohol before use is entirely optional. Some users prefer this extra step for added peace of mind, and that is completely fine.

Read our detailed instruction guide to the microneedling steps here.

1. The cartridge comes in a sterile pack.
2. Double-cleanse (cleanse and repeat) then wipe the skin clean. Fully tie your hair back, away from your face. 
3. Check your cartridge; ensure the needles are in perfect condition (i.e., not bent) and remove any debris.
4. Insert the cartridge into the microneedling pen until it clicks into place.
5. Set your desired needle depth and speed level.
6. Work in small areas and apply Peachaboo Hyaluronic Acid serum to each area before needling. This will help to ensure that the pen does not drag or pull on the skin. The recommended pattern to move the pen for best results is vertical, horizontal, and then diagonal in both directions. Using a light pressure and without dragging, repeat this motion over each area two times.
7. Safely dispose cartridge after every use.

Critical: Alignment Installation Guide

⚠️ Align to Protect the Chip: The Dr. Pen M9 cartridges use sensitive electronic contacts. Follow these steps carefully to avoid damaging the Smart Chip.

1. Locate the Marker
   Find the alignment arrow/mark on the cartridge interface.

2. Match the Pen
   Align the cartridge marker with the corresponding indicator on the Dr. Pen M9 body.

3. Twist to Lock
   Once aligned, twist clockwise to secure.

Warning: Do not force the cartridge into place. Incorrect installation may damage the electronic contact points.
