How to Use

Important: To ensure safety, it is recommended that microneedling cartridges be sterilised before each use. This helps ensure the treatment is safe and hygienic. Here are the steps to sterilise microneedling cartridges:

1. First, ensure that you have all the necessary equipment for sterilisation; 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 sterilisation.
3. Check your cartridge; ensure the needles are in perfect condition (i.e., not bent) and remove any debris.
4. Pour enough alcohol solution into the container and dip the cartridge needle into a sterilisation 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 sterilisation is complete, allow the cartridge to air dry before using it.
7. Finally, your cartridge is ready for use.
