Benefits

• Targeted Scar Revision
  The 18-pin design supports intensive stimulation in focused zones, helping improve the look of deep acne scars and depressed texture by encouraging a smoother appearance.  

• High-Precision Control
  The compact configuration provides better control around complex facial contours such as the upper lip, nasolabial area, nose and glabella, where wider pin layouts can feel less accurate.

• Enhanced Nutrient Delivery
  Creates precise micro-channels that support improved absorption of your microneedling-compatible serums, helping actives reach deeper layers.

• Texture Resurfacing
  Ideal for smoothing the appearance of rough texture, uneven skin grain and surface irregularities caused by previous skin trauma.

• Targeted Localised Repair
  The 18-needle configuration is specifically designed for high-precision treatment of small, stubborn areas.

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.

Here are the steps to microneedling with the cartridges:

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.
