Intelligent Design & Device Compatibility
SnapConnect™ Locking Mechanism
The upgraded SnapConnect™ system ensures a firm, stable connection between cartridge and device, preventing loosening during use and maintaining consistent treatment performance.

Integrated Smart Chip Recognition
Each cartridge features a built-in smart chip that communicates directly with the M9 device to automatically optimize power output and frequency stability, enhancing safety, reliability, and precision.

Ultra-Fine Needle Engineering
All cartridge types use 34-gauge stainless steel needles (0.18 mm diameter) designed to:
Reduce discomfort during treatment
Improve penetration efficiency
Create uniform micro-channels for enhanced serum absorption

Cartridge Types & Recommended Uses
18-Pin Cartridge
Best for targeted treatments such as acne scars, post-acne marks, fine lines, and facial contour refinement. Fewer needles allow precise focus on localized areas that require deeper correction.

36-Pin Cartridge
Ideal for overall skin rejuvenation, improving texture, enlarged pores, dull tone, and mild scarring. Provides wider coverage suitable for full-face treatments.

42-Pin Cartridge
Designed for large treatment areas including stretch marks, body scars, or severe texture concerns. Highest needle density delivers maximum coverage per pass.

Round Nano Cartridge
Perfect for superficial serum infusion treatments using ingredients like hyaluronic acid or Skinbooster. Nano-level penetration is non-invasive, leaves no visible wounds, requires no downtime, and can be used weekly.
