Nano Round cartridges work differently to the standard microneedling pins. Rather than puncturing the skin, they create ultra-fine nano-channels on the surface to boost ingredient absorption, with no downtime. They are designed for gentle, frequent use and pair well with hyaluronic acid serums, brightening actives and skin boosters. Each cartridge includes a built-in smart chip that communicates with the Dr. Pen M9 device, and is individually sealed and sterilised for single use.

Benefits

• Supports up to 97% more effective product absorption compared to topical application alone
• Completely painless, with no numbing cream required
• Leaves skin looking smoother and brighter immediately after use
• Supports ongoing collagen stimulation over time
• Helps refine tone, minimise the look of pores and treat closed comedones
• Helps reduce the appearance of puffiness
• Safe for frequent use, including between standard microneedling sessions

Why You Would Use This

Use the Nano Round cartridge when you want a gentle boost between microneedling sessions, or as a stand-alone treatment for sensitive skin. It suits daily or weekly use without the downtime of traditional microneedling, and nanoneedling can be performed weekly with no recovery time needed.

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 tips are in good condition and free of debris.
4. Soak the cartridge 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 speed using the smart controls on the device.
4. Apply a serum or booster to each area before treatment 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.
