Usage frequency

For nanoneedling, use the device once every week; it can also be used between microneedling sessions. Results may differ for each person; the average initial result can be seen in the first sessions.

Important: Microneedling cartridges must be sanitised before each use to ensure the treatment is safe and hygienic. You must follow these steps carefully to sterilise the microneedling cartridges properly.

Here are the steps to sterilise microneedling cartridges:

  • First, ensure you have all the necessary equipment to sanitise the cartridge: gloves, isopropyl alcohol solution (70% or above) and a clean container to hold the solution.
  • Put on your gloves to avoid contaminating the cartridges during the sterilisation process.
  • Check on your cartridge; ensure the needles are in perfect condition (i.e. not bending) and remove any debris.
  • Pour enough alcohol solution into the container and dip the cartridge needle into a sterilisation container, then soak for a couple of minutes.
  • If you have alcohol solution in a spray model, you can spray it towards the needle head of the cartridge.
  • Once the sterilisation is complete, allow the cartridge to air dry fully before using it.
  • Finally, your cartridge is ready for use.

Please read our detailed instruction guide here.

  • Comprehensive instructions are available on our website under our FAQs section.
  • The cartridge comes in a sterile pack.
  • Double-cleanse (cleanse and repeat), then wipe the skin clean. Fully tie back your hair, away from your face.
  • Work in small areas and add serum to the serum container before needling. This will help ensure the pen does not drag or pull on the skin. For best results, the recommended pattern to move the pen is vertical, horizontal, and then diagonal in both directions. Using light pressure and without dragging, repeat this motion over each area two times.
  • Safely dispose of cartridges after every use.

DO NOT USE

  • On open wounds.
  • On acne or irritated skin.
  • If irritation occurs.
  • One cartridge more than once.

The questions we actually get

Will this fit my pen?

Cartridges are not universal. Match the model in the title to the model printed on your device. If you are unsure, send us a photo of the pen and we will confirm before you order.

Can I use a cartridge twice?

No. They arrive sterile and sealed for one use. A second pass with the same needles is blunter, less sterile and more likely to tear skin than treat it.

How many will I get through?

One per session, and one more if you are treating a second area the same day. Most people at one session a month use ten to twelve a year per area.

What does the pin count change?

Coverage, not depth. Fewer pins concentrate the work for the nose, eyes, hairline and single scars; more pins cover cheeks, forehead and the body in fewer passes. Nano has no needling depth and is for surface refinement between sessions.

Are these genuine?

Yes, sourced through Dr. Pen's own official channel. Non-genuine cartridges are the fastest way to void a warranty and the fastest way to injure your skin.

Before you buy

Make sure this pack fits your pen

Cartridges are model-specific and single use. Check the match, then set your depth before the session.
