Complete guide: Microneedling Needles 12 PIN
The '12 PIN Microneedling Cartridge' is a consumable for Dr. Pen or Dermapen type microneedling devices: 12 micro-needles made of 316L stainless steel, arranged in a circle on a medical-grade plastic support, with a diameter of 7 mm and a threaded attachment system. It is intended for cosmetic/aesthetic specialists and clinics performing microneedling procedures (controlled micro-perforation of the skin). It is a single-use product, individually packaged and sterilized with ethylene oxide (E.O. Gas), ready to be mounted directly onto the device.
How to use
- Before opening, check the integrity of the individual sterile packaging — if it is torn, swollen, or unsealed, the cartridge should not be used.
- Mount the cartridge onto the device via threading (compatible with Dr. Pen A1, A6, A7, M8, Ultima, Dermapen, and other devices with a standard cartridge system), tightening firmly until fully secured.
- Set the desired penetration depth on the device — according to the manufacturer's description, the adjustable range for this needle type is 0.25–2.5 mm, depending on the area and treatment type established by the practitioner.
- Disinfect the skin area to be treated, following the clinic's hygiene protocol.
- Perform the procedure according to the technique learned in professional training, ensuring uniform passes over the treated area.
- After completing the procedure, immediately discard the used cartridge into the sharps waste container — it is single-use, not to be resterilized or reused.
- Clean and disinfect the handpiece/device according to the manufacturer's instructions before mounting a new cartridge for the next client.
Tips from us
- Check before ordering that your device model uses a threaded cartridge system compatible with Dr. Pen/Dermapen — an incompatible mount will not attach correctly.
- Keep unused cartridges in their original sealed packaging, away from moisture, until the moment of use.
- Use a new, unopened cartridge for each client and each session — it is a single-use product, not to be shared between clients.
- If you work with a high professional volume, cartridges can be ordered in larger quantities — check the price per unit for larger orders.
- Do not force the mounting or dismounting of the cartridge — if the thread resists, check the alignment before insisting.
Warning: The manufacturer lists contraindications for use on: areas with active herpes, tattoos, keloid scars, areas with infections, the first 40 days after surgical interventions, veins or broken capillaries, severe solar keratosis, raised moles or warts, rosacea, eczema, psoriasis, epilepsy, pregnancy, and anticoagulant treatment — do not use the product on these areas/persons. The cartridge is single-use: as it involves needles that perforate the skin, reuse or resterilization is contraindicated for hygiene and safety reasons. Handle the used cartridge as sharps waste and dispose of it according to sanitary norms for aesthetic clinics.
Frequently asked questions
Which devices is this microneedling cartridge compatible with?▾
It is compatible with Dr. Pen (models A1, A6, A7, M8, Ultima), Dermapen, and generally with microneedling devices that use a standard threaded cartridge system. If you are unsure about your device model, check its specifications before ordering — the threading system must match.
Can the cartridge be reused for multiple sessions or clients?▾
No. It is a single-use product, individually packaged and sterilized with ethylene oxide. After a single procedure, it must be discarded, regardless of whether all needles 'appear' still usable — resterilization or reuse is not safe for an instrument that perforates the skin.
What is the cartridge diameter and how is it mounted on the device?▾
The cartridge has a diameter of 7 mm and is mounted via threading directly onto the microneedling device head. The needle penetration depth is not adjusted on the cartridge, but on the device, within its allowable range (0.25–2.5 mm, according to the manufacturer's data for this needle type).
Why is the 12-needle configuration a common choice?▾
The 12 micro-needles arranged in a circle provide greater coverage per pass than configurations with fewer needles (e.g., 5 or 9 pins), making them suitable for medium to large areas. The choice of needle count depends on the treated area and the protocol established by the practitioner — for small areas requiring fine precision, cartridges with fewer needles are often preferred.
What contraindications should be checked before using the product on a client?▾
According to the manufacturer, the procedure should not be performed on areas with active herpes, tattoos, keloid scars, local infections, within the first 40 days after surgery, on veins or broken capillaries, severe solar keratosis, raised moles or warts, rosacea, eczema, psoriasis, on individuals with epilepsy, during pregnancy, or under anticoagulant treatment. Check the client's history before starting the procedure.
How should unused cartridges be stored to remain sterile?▾
Store in the original individual sealed packaging, in a dry place, away from extreme temperatures and mechanical damage. Sterility is guaranteed only as long as the packaging remains intact — a cartridge with broken or compromised packaging should not be used.

The 12 PIN microneedling needles are cartridges with 12 micro-needles arranged circularly, offering medium-to-large coverage ideal for complete facial treatments and body areas. The 12-pin configuration is the most popular choice in standard professional microneedling protocols, thanks to exceptional versatility — enough needles for efficient coverage, yet few enough to maintain good control. The 12 needles create a dense micro-perforation pattern stimulating collagen and elastin production over a larger area per pass compared to 5 or 9 pin configurations. Manufactured from superior quality medical stainless steel, each needle is sharpened to nanometric level for clean penetration without tissue laceration. Individual sterilization guaranteed, hermetic packaging with integrity indicator. Compatible with Dr. Pen (A1, A6, A7, M8, Ultima), Dermapen, and compatible devices with standard cartridge systems. Penetration depth controllable from device (0.25-2.5mm) allows treatments from superficial rejuvenation to deep collagen stimulation for scars and stretch marks. The 12 PIN cartridge is the gold standard in aesthetics clinics for anti-aging facial treatments, skin texture improvement, and enlarged pore reduction. Strictly single-use product per sanitary regulations.
