# 12-Pin Microneedle Cartridges for Dr. Pen A7

The 12-Pin Microneedle Cartridges for Dr. Pen A7 size is perfect for anti-aging and improving skin texture.

The cartridges are one-time use only. Do not use them for more than one microneedling treatment, this is to ensure there’s no cross-contamination.

 

Instructions

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