18-Pin Microneedle Cartridges for Dr. Pen M9 (5 Pack)

This cartridge uses a tighter 18-pin needle layout, designed for detailed, high-precision treatment rather than broad coverage. It is suited to smaller or more contoured areas such as the upper lip, nose, glabella and other complex facial zones where a wider pin layout can feel less accurate. Each cartridge includes a built-in smart chip that communicates with the Dr. Pen M9 device, and is individually sealed and EO gas sterilised for single use.

Benefits

• Helps improve the look of deep acne scars and depressed texture through focused, targeted stimulation
• Provides better control around contoured areas like the nose, upper lip and the space between the brows
• Creates precise micro-channels that support improved absorption of microneedling-compatible serums
• Helps smooth the appearance of rough texture, uneven skin grain and surface irregularities
• Designed for high-precision, localised correction in small, stubborn areas

Why You Would Use This

Reach for the 18-pin cartridge when you are treating a specific problem area rather than the whole face, such as a stubborn patch of scarring, a deep line or a contoured zone that benefits from a steadier, more controlled approach.

How to Use Cartridges

Cartridges should be sterilised before each use to keep treatments safe and hygienic.

1. Gather gloves, a 70%+ isopropyl alcohol solution and a clean container.
2. Put on gloves before handling the cartridge.
3. Check the cartridge to make sure the needles are straight and free of debris.
4. Soak the needle tip in the alcohol solution for a couple of minutes, or spray it if using a spray solution.
5. Let the cartridge air dry fully before attaching it to the device.
6. Dispose of the cartridge safely after a single use.

Fitting the Cartridge

The Dr. Pen M9 cartridges contain sensitive electronic contacts, so it is worth aligning them carefully.

1. Find the alignment marker on the cartridge interface.
2. Match it with the corresponding indicator on the M9 device body.
3. Twist clockwise to lock it securely into place.

Avoid forcing the cartridge in. Incorrect installation can damage the electronic contact points.

Using the Dr. Pen M9

1. Double cleanse the skin and tie hair back away from the face.
2. Fit the cartridge as described above. The smart chip will validate and sync automatically.
3. Set your needle depth and speed using the smart controls on the device.
4. Apply a serum or booster to each area before needling so the pen glides smoothly.
5. Work each section with vertical, horizontal and diagonal passes, using light pressure.
6. Dispose of the cartridge safely once you are finished.
