Complete guide: Needles microneedling 36 PIN
This microneedling cartridge with 36 micro-needles is designed for cosmetic clinics and aesthetic practices working on large areas — thighs, abdomen, back, scalp, or extensive areas of the face. The high needle density, arranged in a compact circular matrix, quickly covers the treated area, reducing session time compared to cartridges with fewer needles (9 or 12 PIN). It is screw-mounted onto the device handle, compatible with Dr. Pen, Dermapen, and other standard devices, and is a single-use consumable, individually packaged and sterilized.
How to use
- Check the integrity of the individual sterile packaging — if it appears damaged or unsealed, do not use the cartridge.
- Mount the cartridge onto the compatible device handle (Dr. Pen, Dermapen, or other standard device) using the screw attachment system until firmly secured.
- Disinfect the client's skin before treatment, according to the clinic's hygiene protocol.
- Set the needle depth according to the area and indication — the cartridge allows adjustment between 0.25 and 2.5 mm.
- Work with constant and moderate pressure; the high needle density distributes force over the surface, so no additional pressure is needed.
- Make uniform passes over the treated area, aiming for a uniform erythema (redness with micro-points) as a visual indicator of sufficient exposure.
- At the end, discard the cartridge — it is single-use and cannot be re-sterilized.
- Continue with the post-treatment care products recommended by the clinic's protocol.
Tips from us
- For small and delicate areas (periocular, nose), choose a cartridge with fewer needles, such as 9 or 12 PIN — the 36 PIN is too wide for fine precision.
- At depths over 0.5 mm, anesthetic cream is recommended for client comfort.
- If you are a beginner, practice the technique (constant pressure, movement speed) on a cartridge with fewer needles before switching to the 36 PIN — the high density amplifies any technical mistake.
- Visually check the packaging and lot number before use, not just upon opening.
- If you work with a steady volume of clients, order the cartridges in larger quantities — as single-use consumables, you need a constantly replenished stock.
Warning: The cartridge is a sterile, single-use consumable — do not reuse or re-sterilize after treatment. According to the manufacturer's instructions, treatment with this cartridge should not be applied on: areas with active herpes, tattoos, keloid scars, areas with infections, recently operated skin (less than 40 days after surgery), broken veins or vessels, severe solar keratosis, raised moles or warts, rosacea, eczema, or psoriasis. It is also contraindicated in cases of epilepsy, pregnancy, or treatment with anticoagulants. Check the client's medical history before the session and follow the clinic's hygiene protocol (skin disinfection, gloves, work surfaces).
Frequently asked questions
For which areas is the 36 PIN cartridge recommended?▾
Due to the high needle density, the 36 PIN quickly covers large areas: thighs and abdomen, back, scalp, arms, and extensive areas of the face. For small and delicate areas, such as the eye contour or nose, a cartridge with fewer needles (9 or 12 PIN) is recommended for better control and precision.
Can the cartridge be reused or re-sterilized?▾
No. It is a single-use consumable, individually packaged and sterilized with E.O. (ethylene oxide) gas at the factory. After a single use, it must be discarded — reuse or re-sterilization is not recommended.
Which devices is it compatible with?▾
The cartridge is screw-mounted and is compatible with Dr. Pen, Dermapen, and other standard microneedling devices that use this attachment system.
Is it suitable for someone new to microneedling?▾
The high needle density (36) amplifies any technical error — excessive pressure can increase the risk of excessive bleeding. If you are a beginner, it is advisable to first practice the correct pressure and movement speed on a cartridge with fewer needles, such as a 12 PIN, and switch to the 36 PIN after mastering the technique.
How many passes and how long does a session typically take?▾
According to the manufacturer's description, on the face, 3-4 passes per area are usually sufficient, on the body 4-6 passes, and on the scalp 2-3 passes — fewer than with cartridges with fewer needles, due to the high density. A full facial session takes approximately 20-30 minutes, a scalp session 15-25 minutes, and treatment on large body areas 30-45 minutes per area; actual times depend on the treated surface and each specialist's technique.
Are there any contraindications I should be aware of?▾
Yes. According to the manufacturer, the treatment should not be applied on areas with herpes, tattoos, keloid scars, active infections, or recently operated skin (less than 40 days), and is contraindicated in cases of broken veins/vessels, severe solar keratosis, raised moles or warts, rosacea, eczema, psoriasis, epilepsy, pregnancy, or treatment with anticoagulants. Always check the client's medical history before the session.

The 36 PIN microneedling needles are high-density cartridges containing 36 micro-needles arranged in a tight circular matrix. This high-density configuration is designed for rapid coverage of large surfaces, significantly reducing treatment time compared to cartridges with fewer needles. 36 PIN is the preferred choice for body treatments (stretch marks, surgical scars, extended hyperpigmentation zones), for scalp (hair growth stimulation), and for facial sessions where speed is a priority. The high needle density creates an intensive stimulation effect — more micro-perforations per square centimeter translate to stronger collagen response per pass. Manufactured from medical steel with precision sharpening, individually sterilized. Compatible with Dr. Pen, Dermapen, and standard devices. Adjustable depth (0.25-2.5mm) allows adaptation to different zones and indications. Due to the high needle density, required pressure per needle is lower, which can be more comfortable for patients on large areas. The downside: on small areas requiring precision (periocular, nose), 36 PIN may be too wide — opt for 9 or 12 PIN. Single use only.
