Why Choose an 18-Pin Cartridge?

The 18-needle configuration makes it easy to glide across facial contours for a comfortable, well-balanced microneedling session. It provides versatile coverage for the cheeks and forehead while allowing controlled movement around areas such as the nose, upper lip, nasolabial area and between the brows.

Use the 18-pin cartridge to support skincare routines focused on improving the appearance of fine lines, mild scarring, pigmentation, enlarged-looking pores and uneven skin texture, while promoting a smoother, more refined-looking complexion. For an everyday full-face cartridge within your M8 Max routine, the 18-pin is a versatile place to start.

• 5 × 18-Pin Microneedle Cartridges for the Dr. Pen M8 Max Microneedling Pen

Note: Dr. Pen cartridges arrive in individually sealed, sterile pouches, sterilized 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.

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.
