How do these cartridges fit and work with my M8 or M7S microneedling pen?

The cartridges are engineered to attach directly to the M8 and M7S pen models, clicking into place for secure use. Once fitted, the 16 micro‑needles oscillate with the pen mechanism to create uniform micro‑channels across the skin. Always ensure the pen is powered off when installing or removing cartridges and replace after each treatment to prevent contamination.

• Compatible with M8 and M7S derma pens for a snug connection.
• 16 evenly spaced needles provide smooth coverage.
• Single‑use cartridges help maintain cleanliness between sessions.
• Quick snap‑on design for fast replacement during routines.

Is the 0.25mm needle length safe for at‑home use and beginners?

The 0.25mm needle depth is intended to be minimally invasive and is commonly recommended for home microneedling to improve product absorption and surface texture without deep penetration. It reduces discomfort relative to longer needles and lowers the risk of significant skin trauma when used correctly. Nevertheless, follow basic skin prep and avoid broken or irritated skin.

• 0.25mm depth designed for topical enhancement and surface stimulation.
• Lower discomfort versus longer needles, suitable for new users.
• Avoids sensitive or broken skin areas to reduce irritation risk.
• Use once or twice weekly as part of a careful routine.

What steps should I follow to use these cartridges safely at home?

Begin with a clean face and sanitized pen; apply a thin layer of your chosen serum or gel before treatment. Move the pen in consistent passes—horizontal, vertical, then diagonal—to ensure even coverage while keeping clear of the eyelids and open wounds. Replace the cartridge after one use and follow up with a soothing product to calm the skin.

• Cleanse and disinfect the target area thoroughly before use.
• Apply a compatible serum for better absorption during treatment.
• Roll methodically in multiple directions for even coverage.
• Dispose of each cartridge after one session to keep hygiene standards.

What maintenance and storage tips help preserve cartridge quality?

Keep unused cartridges in their sealed packaging until needed and store them in a cool, dry place away from direct sunlight. Do not reuse cartridges; single‑use disposal prevents cross‑contamination and preserves performance. If a cartridge looks bent or damaged, discard it and use a new one.

• Store in original packaging in a cool, dry environment.
• Do not attempt to sterilize and reuse single‑use cartridges.
• Inspect each tip for damage before attaching to the pen.
• Dispose of used cartridges responsibly per local guidelines.
