What's Included:
10 pack of 16-Pin needle Dr. Pen cartridges, compatible with the A6S Microneedling Pen.
The needles are made of high quality surgical stainless steel and titanium. The 16 pin cartridge head suits smaller areas better and is unique to the A6S model. The 16 pin cartridge features the finest needle gauge at 0.18mm thickness, which allows for precision skin application.
Please note: Ensure to use a new needle cartridge each time you microneedle. 
The needles create tiny micro-channels in the skin's surface. This stimulates the regenerative processes that naturally take place in the skin everyday. This, in turn, stimulates an increased production of collagen and elastin causing the skin to become firmer, for scars to gradually reduce and for wrinkles to smooth out. The Pen can be used multi-directionally so the treatments can be performed on any area of the face, neck, neckline, stomach, thighs, or buttocks.

Important: Microneedling cartridges must be sterilised before each use to ensure the treatment is safe and hygienic. It is essential to follow these steps carefully to ensure that the microneedling cartridges are properly sterilised. Here are the steps to sterilise microneedling cartridges:
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.
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 before using it.
Finally, your cartridge is ready for use.
