Complete guide: Needles microneedling 9 PIN
This cartridge is a disposable accessory for microneedling pen-type devices — it attaches via screw thread to the device and has 9 micro-needles arranged in a circle, designed for a balance between precision and working speed on medium areas of the face and neck. It is compatible with devices that use a standard cartridge system, such as Dr. Pen, Dermapen, and equivalents. It suits practitioners who need a versatile setup, good for most facial microneedling protocols.
How to use
- Check the sealed individual packaging before opening — the cartridge is sterile, sterilized with ethylene oxide (E.O. Gas), and should not be used if the packaging is damaged.
- Mount the cartridge onto the device using the threaded attachment system, screwing it firmly until it is fully secured.
- Adjust the penetration depth on the device, within the available range of 0.25–2.5 mm, depending on the treated area.
- Prepare and disinfect the skin according to your working protocol before starting the treatment.
- Perform the treatment with controlled movements, adapting the device's pressure and speed to the treated area.
- At the end, disassemble the cartridge and dispose of it immediately in a sharps container — it is single-use.
- Do not reuse the same cartridge for another session or on another patient; for each new treatment, use a new cartridge from sealed packaging.
Tips from us
- Use a new cartridge for each patient and each session — the product is explicitly marked as single-use.
- Check before ordering whether your device has a threaded attachment system compatible with this type of cartridge.
- For more sensitive areas of the face, start with lower depths from the device's adjustable range.
- Keep multiple cartridges on hand when treating extended areas of the face to avoid interrupting the session.
- Store unused cartridges in their original packaging, in a dry place, until ready for use.
- Read the list of contraindications before each treatment — some situations (e.g., pregnancy or anticoagulant therapy) preclude use.
Warning: This is a sterile, single-use product with needles — handle with care and dispose of after each use in a sharps container, never in household trash. Do not use on areas with active herpes, tattoos, keloid scars, infections, raised moles or warts, rosacea, eczema, psoriasis, within the first 40 days after surgery, on persons with broken veins or blood vessels, severe solar keratosis, epilepsy, during pregnancy, or if the patient is on anticoagulant therapy. Visually inspect the packaging before use; do not resterilize or reuse the cartridge.
Frequently asked questions
Which microneedling devices is this cartridge compatible with?▾
It is compatible with devices that have a threaded attachment system for standard cartridges, including Dr. Pen, Dermapen, and equivalents. Check your device's attachment type before ordering to ensure compatibility.
Why should I choose the 9 PIN configuration over others?▾
9 PIN offers a balance between precision and coverage speed: it allows more control on areas requiring attention, compared to configurations with more needles which cover larger surfaces but with less point precision. The choice depends on your protocol and the treated area.
Can the cartridge be reused for another session or on another patient?▾
No. The cartridge is single-use, individually packaged, and sterilized with ethylene oxide. After each treatment, it is disposed of in a sharps container; it should not be resterilized or reused, not even on the same patient at a later session.
What penetration depth can I set with this cartridge?▾
The depth is adjusted directly on the device, within the range of 0.25–2.5 mm, allowing adaptation to skin thickness and treated area. The exact depth choice depends on each practitioner's clinical protocol.
What is the cartridge made of and how is it sterilized?▾
The needles are made of 316L stainless steel, mounted on a medical-grade plastic cartridge. Each cartridge is individually packaged and sterilized with ethylene oxide (E.O. Gas) before delivery.
Are there contraindications I need to consider before treatment?▾
Yes. The product should not be used on areas with active herpes, tattoos, keloid scars, infections, raised moles or warts, rosacea, eczema or psoriasis, within the first 40 days after surgery, on persons with broken veins or blood vessels, severe solar keratosis or epilepsy, during pregnancy, or if the patient is on anticoagulant therapy.

The 9 PIN microneedling needles are cartridges with 9 micro-needles arranged in a compact circular configuration, designed for microneedling treatments with medium coverage on pen-style devices. The 9-pin configuration offers an optimal balance between precision and coverage speed — concentrated enough for targeted treatments, yet with sufficient needles to work efficiently on medium areas such as cheeks, forehead, or neck. Each individual needle penetrates the skin at the depth set on the device, creating micro-channels that stimulate collagen production through the Collagen Induction Therapy (CIT) process. The 9 circularly arranged needles create a uniform perforation pattern, reducing the risk of overlap or untreated zones. Manufactured from medical stainless steel, individually sterilized, and hermetically sealed. Compatible with Dr. Pen, Dermapen, and equivalent devices with standard cartridge systems. Penetration depth is adjusted from the device (0.25-2.5mm), allowing adaptation to skin thickness and therapeutic indication. The 9 PIN cartridge is one of the most versatile configurations, suitable for both facial treatments (wrinkles, acne scars, enlarged pores) and neck/decolletage areas. Strictly single-use product — dispose in sharps container after use. Ideal for practitioners seeking an all-around cartridge for most microneedling protocols.
