Nano needle cartridges are designed primarily to enhance product absorption rather than create deep micro-channels in the skin. They are ideal for applying serums, active ingredients and skincare products to improve penetration and overall treatment effectiveness. Nano needling is gentle and suitable for frequent treatments, making it an excellent choice for giving an instant glow with no downtime.

Here is the cartridge selection guide for more information.

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.

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.
