Nano Round Cartridges with Integrated Smart Chip for Dr Pen M9
Achieve effortless, radiant skin with the Nano Round Replacement Cartridges for Dr. Pen M9 Microneedling Pen (5 Pack). Unlike traditional microneedling cartridges, Nano Round cartridges do not puncture the skin. Instead, they create ultra-fine nano-channels on the surface, allowing active skincare ingredients to absorb up to 97% more effectively than topical application alone. They are ideal for applying serums, active ingredients and skincare products to improve penetration and overall treatment effectiveness.
