Ultra-Fine Transdermal Dynamics
Pain and excessive redness are caused by thick, blunt needles displacing too much tissue. The official M8/M7S cartridges utilize an Ultra-Fine 16-Pin Transdermal Gauge (the thinnest needles in the classic lineup). This micro-gauge architecture allows the titanium pins to slip past pain receptors and enter the dermis with minimal resistance, ensuring rapid healing and reduced downtime.
The Danger of Hooked Needles
Because the M8/M7S needles are ultra-fine, they are incredibly sharp but fragile. After a single full-face pass, the microscopic tips bend into microscopic "hooks." If you attempt to reuse the cartridge, these invisible hooks will snag and rip your epidermis, causing permanent track marks.
Clinical Protocol & Disposal
Installation
Lock securely into the A1 heavy-duty chassis.
Execution
Glide gently. The ultra-fine needles require very little pressure to penetrate.
Disposal
Dispose of immediately. Do not reuse, as the ultra-fine tips bend instantly.

FAQs
Please read our FAQs page to find out more.
Q1: Why is the 16-pin M8/M7S cartridge less painful?
A: The scalp's high bacterial load contaminates the cartridge instantly, and the thick tissue blunts the needles. Reusing it risks severe scalp infections and torn hair follicles.
Q2: Will the M8 cartridges fit the M8S?
A: No. The original M8 uses a classic bayonet slot, while the M8S uses a newer 3-Slot locking mechanism. They are not interchangeable.
Q3: Can I reuse the 16-pin cartridge if I boil it?
A: No. Boiling does not fix the physical damage. The ultra-fine tips bend into microscopic hooks after one use. Reusing them will tear your skin.
Q4: Which is better for the face: 16-pin or 36-pin?
A: The 16-pin is far superior for the face. The 36-pin is too dense and causes the 'bed of nails' effect on thin facial skin, whereas the 16-pin penetrates deeply and cleanly.
Q5: What is the Nano cartridge used for on the M8?
A: Nano cartridges are used for painless, daily transdermal delivery of serums (like Hyaluronic Acid or Vitamin C) without causing any bleeding or downtime.
Q6: Do these cartridges prevent blood from entering the pen?
A: Yes, official M8 cartridges feature a built-in anti-backflow membrane that acts as a firewall between your blood and the pen's internal motor.
