Complete guide: Microneedling Needles 24 PIN
This 24-needle microneedling cartridge attaches to "pen" type devices (compatible, among others, with Dr. Pen) and is designed for professional aesthetic procedures on the face and body — from improving skin texture to working on acne scars or fine lines. The 24-pin configuration offers greater coverage of the treated area compared to cartridges with fewer needles, which means shorter sessions on larger areas. It is a single-use consumable, individually packaged and sterilized, designed for studios and clinics working with multiple clients.
How to use
- Check before ordering/use that your pen model accepts a threaded locking system, like this cartridge.
- Prepare the treatment area: clean and disinfect, according to your clinic's protocol.
- Open the individual sterile packaging right before the procedure, without touching the needle tips.
- Screw the cartridge onto the device's tip until it is firmly secured, using the threaded system.
- Set the penetration depth on the device according to the area and treatment type — start cautiously and adjust based on the skin's tolerance.
- Perform the treatment with controlled movements and even pressure, following the microneedling technique.
- Finally, turn off the device, remove the cartridge and discard it — it is single-use, cannot be re-sterilized or reused.
- Disinfect the device body (handle) according to your clinic's hygiene protocol, separate from the cartridge.
Tips from us
- Use a new cartridge for each client, without exception — this prevents cross-contamination between sessions.
- Check the integrity of the sterile packaging before opening; if it appears tampered or damaged, do not use it.
- Briefly discuss the relevant contraindications with the client before treatment, not just out of habit.
- Increase the penetration depth gradually, from one session to the next, especially with new clients or on sensitive areas.
- Store unopened cartridges in a dry place, away from direct light and extreme temperatures, until use.
- Have a sharps disposal container ready for proper disposal of the used cartridge.
Warning: The needles are made of 316L stainless steel, the cartridge of medical-grade plastic, individually packaged and sterilized with ethylene oxide (E.O. Gas) — the product is single-use: do not re-sterilize or reuse on another client. According to the manufacturer's instructions, do not use on areas with active herpes, tattoos, keloid scars, skin infections, within the first 40 days after surgical procedures, on broken veins or blood vessels, severe solar keratosis, raised moles or warts, rosacea, eczema, psoriasis, on persons with epilepsy, during pregnancy, or on clients under anticoagulant treatment. Handle with care — these are sharp needles with a risk of puncture — and dispose of the used cartridge according to regulations for sharp medical waste.

The 24-pin microneedling needles are high-precision professional consumables designed for microneedling procedures performed with pen-type devices. The configuration of 24 micro-needles uniformly arranged ensures optimal coverage of the treated surface, stimulating natural collagen and elastin production by creating controlled micro-channels in the skin. The needles are manufactured from the highest quality surgical stainless steel, guaranteeing perfect sharpness, sterility, and maximum client safety. Each needle is individually calibrated to ensure uniform penetration at the same depth, eliminating the risk of uneven treatment. The 24-pin cartridges are ideal for treating larger areas of the face and body, delivering fast and efficient results. They are frequently used for skin rejuvenation, acne scar reduction, fine line smoothing, skin texture improvement, and enhancing active serum absorption. Compatible with most pen-type microneedling devices on the market, these cartridges mount quickly and are easily replaced between clients. Each cartridge is individually packaged and sterilized, intended exclusively for single use to maintain hygiene standards. Material quality and manufacturing precision make these needles a trusted choice for professional clinics and studios. The 24-pin microneedling treatment stimulates the body's natural healing response by creating controlled micro-injuries in the dermal layer. This process activates Type I and Type III collagen production, and results become progressively visible in the weeks and months following treatment. Adjustable penetration depth allows treatment personalization based on the specific area and client condition.
Frequently Asked Questions What advantages does the 24-pin configuration offer? The 24-pin configuration provides greater coverage of the treated surface compared to cartridges with fewer pins. This translates to shorter sessions and more uniform results on extended areas. It is ideal for facial and body treatments requiring fast and efficient coverage. Are these needles single-use? Yes, each 24-pin microneedling cartridge is intended exclusively for single use. This rule is essential for maintaining hygiene and safety standards, preventing the risk of cross-contamination between clients. After use, the cartridge is disposed of responsibly. What devices are these compatible with? The 24-pin cartridges are compatible with most pen-type microneedling devices available on the market. The standard mounting system allows quick and secure installation. Checking compatibility with your specific pen model before purchase is recommended. What conditions can be treated with 24 PIN microneedling? Microneedling with 24 pins is effective for skin rejuvenation, acne scar reduction, fine line and wrinkle smoothing, skin texture improvement, enlarged pore reduction, and enhanced active serum absorption. It is a versatile treatment with multiple applications in professional aesthetics. What material are the needles made from? The needles are manufactured from the highest quality surgical stainless steel. This material offers superior sharpness, corrosion resistance, and excellent biocompatibility. Each needle is individually calibrated to ensure uniform and safe skin penetration. How is the cartridge mounted on the pen? The cartridge mounts quickly and intuitively onto the pen-type microneedling device through the standard mounting system. The cartridge is inserted into the pen tip until it locks into position. The locking mechanism ensures stability during the procedure and prevents accidental detachment. What penetration depth is recommended? Penetration depth varies depending on the treated area and target condition. For face, 0.25-1.0 mm is generally recommended, while for body up to 2.0 mm. Depth is set on the microneedling device and must be adjusted by a qualified professional. Are the needles sterilized? Yes, each microneedling cartridge is sterilized and individually packaged in sealed packaging. Sterility is guaranteed until package opening. Do not use cartridges with damaged or previously opened packaging, as sterility can no longer be guaranteed. How many treatments can I perform with one package? Each cartridge is intended for a single treatment on a single client. The number of treatments you can perform depends on the number of cartridges in the package. Plan your purchase based on client volume and never reuse a used cartridge. Is 24-pin microneedling painful? Discomfort is minimal when the procedure is correctly performed by a professional. A topical anesthetic cream can be applied before treatment to maximize client comfort. The 24-pin cartridges distribute pressure evenly, which can reduce discomfort sensation compared to configurations with fewer pins.
