Infuse your serums deeper into the skin with the Square Nano Pin Cartridges for Dr. Pen HydraPen H3. Improve your skin’s product absorption and stimulate more collagen production between microneedling sessions with these cartridges.

Nano-needling is pain-free, with zero downtime, and can be done weekly. The nano needles are super fine (approx ? size of a human hair) and only puncture the stratum corneum.

Always use a new cartridge for each microneedling treatment. Do not use the same cartridge for more than one microneedling session.

Each cartridge comes in a sterile pack.
