How do these cartridges fit my Dr. Pen A6 device?

The cartridges are manufactured to be compatible with Dr. Pen A6 series and several other common models (N2, M5, M7). They attach by a simple push‑and‑click mechanism that aligns the pin cluster with the pen drive shaft. Always confirm a secure fit before use.

• Compatibility: Dr. Pen A6, N2, M5, M7
• Attachment: push‑in, click to lock
• Use check: ensure cartridge is seated and spins smoothly

What are the needle specifications and why choose 0.25 mm?

Each cartridge houses 24 fine needles at a fixed 0.25 mm penetration depth. This short length is commonly selected for surface treatments like improving topical product absorption, addressing superficial texture, and introducing the skin to microneedling routines with lower irritation risk. It is not intended for deep clinical procedures.

• Needle count: 24 pins per cartridge
• Needle length: 0.25 mm (fixed)
• Best for: surface care and product delivery support

How do I store and handle the cartridges safely?

The pack includes a compact protective case to keep cartridges clean and organized when not in use. Cartridges are for single use only; discard after treatment to avoid contamination. Always handle by the plastic base and avoid touching the needle tips.

• Storage: use the included protective case
• Hygiene: single‑use and dispose after one session
• Handling: grasp the base, never touch needles

What should I expect while using these at home?

At the 0.25 mm setting, sessions are generally gentle and brief, suitable for short treatments that focus on surface concerns and product infusion. Users should follow device instructions, cleanse skin thoroughly, and use appropriate topical serums. If you are new to microneedling, follow a conservative routine and monitor skin response.

• Session feel: mild, brief sensations
• Preparation: cleanse and disinfect skin before use
• Aftercare: apply soothing serums and avoid sun exposure
