Complete guide: Needles microneedling 42 PIN
This 'Microneedling Cartridge 42 PIN' is a professional consumable for microneedling devices with a threaded cartridge system, compatible with Dr. Pen (and, according to the manufacturer's description, with other devices using the same standard cartridge system, including Dermapen). Featuring 42 micro-needles made of 316L stainless steel mounted on a medical-grade plastic cartridge, it is designed for rapid coverage of large areas during professional microneedling sessions. It is individually packaged, sterile, and intended for single-use only by professionals in the dermo-cosmetic aesthetics field.
How to use
- Check the integrity of the individual sterile packaging before opening; if damaged, do not use the cartridge.
- Mount the cartridge onto the device using the threaded attachment system, compatible with Dr. Pen and other devices with a standard cartridge system.
- Disinfect the treatment area according to the standard protocol of your clinic/office.
- Adjust the needle depth directly on the device, within the range of 0.25–2.5 mm, depending on the treated area and the procedure's objective.
- Before treatment, review the indications and especially the contraindications (see the warnings section) — certain conditions or medical situations preclude use.
- Perform the treatment with controlled movements and uniform passes over the targeted area.
- At the end of the session, discard the cartridge — it is single-use and cannot be re-sterilized or reused.
- Apply the post-treatment care recommended by the clinic/device manufacturer for the treated area.
Tips from us
- With 42 needles, the density is the highest in the cartridge range, making it especially suitable for large body areas (thighs, abdomen, scalp) where rapid coverage matters.
- For delicate facial areas (periorbital, lips, nose, neck), prefer cartridges with fewer needles; the 42 PIN is better suited for the body or larger facial areas at shallow depths.
- Choose a device with a sufficiently powerful motor — with 42 needles penetrating simultaneously, the resistance encountered is higher, especially at greater depths.
- Do not reuse or re-sterilize the cartridge — it is designed as a single-use product precisely for patient safety.
- Store unopened cartridges in their original sterile packaging in a dry place until use.
- Strictly adhere to the list of contraindications before any session — some medical conditions of the client completely exclude the treatment.
Warning: Single-use product, intended exclusively for professionals in dermo-cosmetic aesthetics — not for home use. Made of 316L stainless steel, with a medical-grade plastic cartridge, individually packaged and sterilized. Do not use the device with this cartridge on: areas with active herpes, tattoos, keloid scars, areas with infections, recently operated areas (less than 40 days post-surgery), broken veins or capillaries, severe solar keratosis, raised moles or warts, rosacea, eczema, psoriasis; do not use on persons with epilepsy, during pregnancy, or by persons taking anticoagulant medication. If in any doubt about skin condition or medical conditions, a medical/dermatological evaluation is recommended before treatment.
Frequently asked questions
What does '42 PIN' mean on this cartridge?▾
'PIN' refers to the number of micro-needles mounted on the cartridge — in this case 42, arranged in a dense configuration. The more needles there are, the larger the surface area covered per pass, which reduces the time needed for treating large body areas.
Which devices is this cartridge compatible with?▾
According to the manufacturer's description, the cartridge is compatible with Dr. Pen, Dermapen, and generally with devices that use the same standard threaded cartridge system. We still recommend verifying exact compatibility with your specific device model before ordering.
Can it be used on the face or only on the body?▾
It can be used on the face at shallow (superficial) depths, for areas like cheeks or forehead. On delicate areas — periorbital, lips, nose, neck — it is not recommended, as the high needle density is designed primarily for extended body areas or scalp treatments.
Can the cartridge be re-sterilized and reused?▾
No. It is a single-use product — individually packaged and sterile until opened. After one session, the cartridge is discarded; it is not cleaned or re-sterilized for subsequent use, precisely to guarantee the safety and hygiene of the treatment.
What depth should I choose for the treatment?▾
The needle depth is adjusted directly on the device, within the range of 0.25–2.5 mm, depending on the treated area and the procedure's objective (e.g., superficial exfoliation vs. deeper stimulation).
Who can use this cartridge — and what should we consider when choosing?▾
It is intended exclusively for professionals in dermo-cosmetic aesthetics, not for home use. When choosing, consider the area you predominantly treat: for the body and large areas, the 42-needle density is an advantage; for fine work on the face, cartridges with fewer needles offer better control.

The 42 PIN microneedling needles are the highest-density needle cartridges in the range, containing 42 micro-needles arranged in an ultra-dense circular matrix. This maximum configuration is designed for the fastest possible coverage of large surfaces, dramatically reducing treatment time for extended body areas. With 42 needles penetrating simultaneously, each device pass stimulates a maximum number of collagen micro-channels, amplifying the skin's regenerative response. The configuration is ideal for intensive body treatments: extensive stretch marks on thighs and abdomen, large surgical scars, cellulite zones, and full scalp treatments. Manufactured from medical stainless steel with ultra-precision nanometric sharpening. Each needle creates a clean micro-perforation without lateral laceration, maximizing stimulation without excessive trauma. Individual sterilization through gamma irradiation, hermetic packaging with integrity indicator. Compatible with Dr. Pen, Dermapen, and compatible devices with standard cartridge systems. Depth adjustable from the device (0.25-2.5mm). Because pressure distributes across 42 needles, force per needle is minimal, making treatment surprisingly comfortable on large areas. Strictly single-use product, intended exclusively for dermatological-cosmetic aesthetics professionals.
