3-Slot Bayonet Lock Dynamics
High-torque motors (like the A9 and A11) will shatter cheap cartridges. These official flagship replacements feature the proprietary 3-Slot Bayonet Lock. This triple-locking mechanism ensures absolute zero lateral vibration (wobbling) at 15,000 RPM, guaranteeing flawless, 90-degree vertical strikes that prevent "track mark" scratches on the face.
The 18-Pin Clinical Advantage
The exclusive 18-pin configuration (not found on older models) is the ultimate sweet spot for treating deep atrophic acne scars. It provides enough space between needles to penetrate thick fibrotic tissue without the "bed of nails" resistance effect, triggering massive localized Type I Collagen synthesis.
Clinical Protocol & Disposal
Installation
Align the 3 slots and twist to lock securely.
Execution
Select the 18-pin for deep scars. Ensure the device is running at high speed to prevent dragging.
Disposal
Dispose of the cartridge in a bio-hazard sharps container immediately after the session.

FAQs
Please read our FAQs page to find out more.
Q1: Why is the 18-pin cartridge better than the 36-pin for deep scars?
A: The 18-pin has needles spaced further apart. This prevents the 'bed of nails' effect, allowing the needles to slice deeply into hardened scar tissue rather than bouncing off the surface.
Q2: Will these fit the original M8 or A6?
A: No. These feature a proprietary 3-Slot Bayonet Lock designed specifically for the newer generation flagship models (M8S, A8S, A9, A11).
Q3: What does the anti-backflow membrane do?
A: It is a critical silicone barrier inside the cartridge that prevents blood, serum, and biological fluids from traveling up the needle shaft and destroying your pen's internal motor.
Q4: Can I sanitize the 18-pin cartridge with alcohol and reuse it?
A: Never. Alcohol cannot clean the inside of the anti-backflow chamber, and the high-torque motor permanently blunts the needles after one use.
Q5: What is the Nano cartridge used for on these high-power pens?
A: Nano cartridges are used for daily or weekly painless serum infusion. They do not puncture the dermis, making them perfect for boosting hydration without downtime.
Q6: Why is the 3-Slot lock so important?
A: Older cartridges vibrate laterally at high speeds, causing micro-scratches on the skin. The 3-Slot lock rigidly anchors the cartridge, ensuring perfect 90-degree vertical strikes.
