Derma Pen & Microneedling Pen Wholesale

Every microneedling session comes down to the part that actually touches the skin. The pen supplies the motion, but the cartridge supplies the needles, the spacing, and the sterile state, which is why the TBPHP M1 cartridge line gets as much attention at the factory as the pen itself. This page covers the heads in the range, how to match a head to a treatment, what single use packaging really means, and what buyers should check before ordering cartridges in volume.

The Range at a Glance

The M1 system uses press fit cartridges that share one collar design, so the same pen body accepts the full range of heads. Five configurations cover the treatments that home users, clinics, and body specialists actually book.

The 12 pin head places a small group of needles over a compact area. It concentrates each pass on fine lines, scar edges, and zones that need precision rather than speed. Users who want to work slowly around the eye area or along a scar border reach for this head first.

The 24 pin head splits the difference between precision and coverage. It treats a wider surface than the 12 pin while keeping the sensation gentler than a dense head, which makes it a common choice for first sessions and for clients with sensitive skin.

The 36 pin head is the workhorse of the range. It spreads the same motor energy across more needles, so pressure feels even and full face sessions stay comfortable. In the starter kit it ships together with the 12 pin head, giving new buyers one precise option and one full face option in the same box.

The 42 pin head packs the densest pattern and suits larger areas where even micro channel coverage matters more than pinpoint control. Body protocols, scalp work, and broad texture treatments are where this head earns its place.

The Round Nano head works differently. Its tips are finished so the head glides over the surface without puncturing the skin, which makes it the gentlest option for sensitive zones and for users who want a light session between deeper treatments.

Matching a Head to Depth and Experience

Choosing a head and choosing a depth are two separate decisions, and both depend on the area being treated. On the face, most at home users keep the depth between 0.25 mm and 0.5 mm with a 24 pin or 36 pin head. Deeper lines and texture work move into the 0.5 mm to 1.0 mm range and suit the 12 pin head, where a smaller contact area keeps deeper passes controlled. Depths beyond that belong to professional protocols. Because every cartridge holds its needles at a fixed exposed length, the depth dial on the pen controls how far the needles enter, and the head choice controls how densely the skin is treated. The two settings work as one system.

New users often ask which combination to start with. The answer used by most clinics is a 24 pin or 36 pin head at 0.25 mm to 0.5 mm for the first month, then a move to the 12 pin head only if a specific scar or line needs more focused work. Round Nano sessions can fill the weeks in between for clients who react to needle sensation. Area by area guidance and compatibility notes are kept on the cartridge specifications page.

Sterile by Design

Every M1 cartridge is sterilized with ethylene oxide and sealed in its own pouch before it leaves the cleanroom. The pouch is the safety boundary. Once it opens, the head is a single session tool, and that rule is non-negotiable. Lot numbers printed on each pack let a clinic or a brand trace any batch back to its production records, which matters for audits and for after sales questions. Needles are medical grade stainless steel with a geometry tuned for clean entry and minimal drag, and the molded housing holds the needles rigid so the pattern does not shift mid session.

A lead quality inspector at the Guangzhou plant describes the standard this way. The day a head leaves the sterile tunnel, it has to behave exactly like the head that left the same line the week before. Nothing about the customer's skin care routine should depend on which batch they opened.

One Collar for the Whole Range

The press fit collar is the detail that makes the range practical. Every head in the M1 line clicks onto the same pen body, so a clinic does not need separate devices for fine, standard, and body work, and a home user can switch from a 36 pin face session to a Round Nano touch up in seconds. The collar seats each cartridge firmly and releases it with a clean turn when the session ends. Because the heads are disposable and the collar is user serviceable, the pen body stays clean while the consumable carries the single use discipline.

Where the Heads Come From

The M1 cartridge line is produced under the TBPHP brand by Guangzhou Xingyun E-Commerce Co., Ltd., the same factory that builds the M1 pen. About fifteen years of needle geometry, molding, and sterile packaging experience sit behind the range, and cartridge assembly runs inside a 2,000 square meter cleanroom with monthly capacity of about 500,000 units. Devices and cartridges carry CE, UKCA, and RoHS certification, and shipments can include function testing records, needle sharpness checks, and cartridge lot traceability for clinic audits. Buyers who want to verify quality controls before ordering can review the manufacturing standards page. Brands planning their own cartridge program can follow the OEM and ODM process page from sample to mass production.

Questions Buyers Ask Most

These are the cartridge questions the TBPHP support team answers most often, with the short version of each answer.

How Many Sessions Does One Cartridge Last

One cartridge is one session. The sterile state ends when the pouch opens, and needles dull with use, so reusing a head trades safety and comfort for a few dollars saved. Buy fresh heads and treat every session as single use.

Which Head Should a First Time Buyer Choose

Start with the 24 pin or 36 pin head at 0.25 mm to 0.5 mm depth. Both spread pressure evenly enough for a comfortable first session, and the starter kit includes the 36 pin option by default.

Can the Same Head Be Used on Different People

No. A used head cannot be safely cleaned or shared because needle contact breaks the sterile state. Clinics assign one fresh cartridge per client per session and log each lot number for traceability.

Do All M1 Cartridges Fit the Same Pen

Yes. The 12 pin, 24 pin, 36 pin, 42 pin, and Round Nano heads all use the same press fit collar and fit the M1 pen body. Compatibility details and depth notes are listed on the cartridge specifications page.

What Should a Buyer Check Before a Bulk Order

Confirm the head pattern, the pouch seal, the lot number placement, and the expiry policy on each box. Request a sample run first, and ask for the batch records that will accompany the shipment so clinic audits stay simple.
