gdbanlimi Microneedling Pen Cartridges 16‑Pin 0.25mm — 20‑Pack for M8/M7S, Sterile Single‑Use

These gdbanlimi replacement cartridges are 16‑pin, 0.25mm microneedling heads sold in a 20‑piece pack and designed for safe, beginner‑friendly use with M8 and M7S derma pen models.

Lightweight and easy to swap, these single‑use cartridges give you a safer alternative to a traditional roller by attaching to compatible derma pens for focused, at‑home skin treatments. Each cartridge contains 16 stainless‑tipped needles set to a shallow 0.25mm depth — a length chosen to be gentle for first‑time users while still allowing even topical product delivery and controlled resurfacing motions. The pack includes 20 sterile, individually sealed heads so you can replace tips between sessions for hygiene and convenience.

How do I use these cartridges safely at home?

Start with clean, dry skin and any topical you plan to work with. Snap a fresh cartridge into your compatible M8 or M7S pen, glide the pen evenly across the treatment area in straight passes, and avoid broken skin or the eye area. After use, dispose of the cartridge and follow with a soothing serum or sunscreen as appropriate.

• Cleanse area thoroughly before treatment.
• Apply a thin layer of product if desired (serum or numbing cream if recommended).
• Move the pen in one direction, then repeat perpendicular passes for even coverage.
• Discard the cartridge after one session to maintain hygiene.

What makes the 16‑pin, 0.25mm size a good choice?

The 16‑pin layout balances coverage and precision, giving you uniform micro‑channels without requiring long needle lengths. At 0.25mm the needles are shallow enough for beginner comfort but effective for improving topical absorption; this length is commonly recommended for at‑home refreshes rather than deeper clinical treatments.

• 16 pins for even, consistent contact across the skin.
• 0.25mm length preferred for first‑time users and maintenance sessions.
• Single‑use design reduces cross‑contamination risk.

Are these cartridges compatible with my derma pen?

They are made to fit many popular derma pens sold as M8 and M7S models; the attachment mechanism and diameter are matched to those pens' heads. If your device is labeled M8 or M7S or lists compatible cartridges of similar shape, these should click into place securely. Always confirm model compatibility before purchase.

• Designed for M8 and M7S style derma pens.
• Snap‑in fitting for quick cartridge changes.
• Individually sealed packs for sterile storage until use.

Who is this for? These 20 replacement cartridges suit anyone using an M8 or M7S microneedling pen who wants a hygienic, cost‑effective supply of shallow, beginner‑friendly tips. They’re ideal for people performing routine at‑home maintenance, skincare enthusiasts testing topical absorption, or practitioners who prefer disposable heads between clients. Not intended for deep clinical procedures — choose a professional setting for deeper treatments. Always follow your device manufacturer’s guidance and standard safety steps when microneedling.
