Key Features
- Bulk 50-Count Cartridge Set: This professional pack includes 50 individually sealed, sterile cartridges. Perfect for busy clinics, med spas, tattoo studios, or dedicated home users who microneedle regularly. Save money per unit compared to buying small packs.
- Universal Bayonet Compatibility: Designed specifically for Dr. Pen Ultima M8 devices. The bayonet-style connection ensures a secure, wobble-free fit during treatment. Works with other M8-compatible pens (check your device manual).
- Multiple Pin Configurations for Every Need: Choose from 11-pin (fine lines), 16-pin (general rejuvenation), 24-pin (scar treatment), 36-pin (stretch marks), 42-pin (large areas), Nano (surface exfoliation), 3D Nano (texture improvement), or 5D Nano (deep penetration).
- Ultra-Thin 0.18mm Needles: The ultra-fine needle diameter creates micro-channels with less pain, bleeding, and erythema compared to thicker needles. High-speed vertical penetration minimizes epidermal damage while maximizing collagen induction.
- Sterile, Disposable, and Safe: Each cartridge is pre-sterilized and packaged in a top sterilization pouch. Single-use design eliminates cross-contamination risks. CE certified for both commercial and home use. No bruising, infection, or discoloration when used correctly.
Compatibility and Best Use
- Dr. Pen M8 Device Compatibility: These cartridges are specifically designed for the Dr. Pen Ultima M8 system. They use a bayonet locking mechanism. NOT compatible with older Dr. Pen models (A6, A7, M5) or other brands unless specified.
- Skin Rejuvenation Treatments: Use for fine lines, wrinkles, acne scars, surgical scars, stretch marks, enlarged pores, and uneven skin texture. The micro-channels increase absorption of serums, growth factors, and vitamin C by up to 80%.
- Tattoo and Permanent Makeup: 11-pin and 16-pin cartridges work well for tattoo shading, eyeliner, lip blush, and brow microblading touch-ups. The disposable design ensures hygienic practice.
- Scalp Microneedling: 36-pin and 42-pin cartridges are excellent for scalp treatments to stimulate hair growth. The wider pin count covers more area quickly while minimizing discomfort.
- Home and Professional Use: Suitable for estheticians, dermatology clinics, tattoo artists, and informed home users. Always follow proper sterilization and safety protocols.
Installation Tips
- Loading the Cartridge: Ensure your Dr. Pen M8 device is turned off. Align the bayonet tabs on the cartridge with the slots in the pen head. Push gently and twist clockwise until you feel a secure click. Do not force.
- Needle Depth Adjustment: The Dr. Pen M8 allows you to adjust needle length from 0mm to 2.5mm. For sensitive areas (face, neck), start with 0.25-0.5mm. For body scars or stretch marks, use 1.0-2.0mm. Nano tips are for surface exfoliation only (0.1-0.2mm).
- Pre-Treatment Prep: Cleanse skin thoroughly and apply a numbing cream if needed (for depths over 0.5mm). Always use a new, sterile cartridge for each client or body area. Never reuse cartridges.
- During Treatment: Hold the pen perpendicular to the skin. Use light, even pressure with gliding or stamping motions. Avoid staying in one spot for more than 2 seconds. The built-in spring mechanism adjusts to contours.
- Aftercare and Disposal: After use, remove the cartridge and dispose of it in a sharps container. Never recap or try to clean a used cartridge. Apply hyaluronic acid or calming serum immediately after treatment.

Warnings and Safety Notes
For single use only – never reuse or share cartridges. Reusing needles can cause infection, scarring, and cross-contamination.
Do not use if the sterile package is damaged, opened, or expired. Return unopened cartridges if packaging is compromised.
Always perform a patch test on a small area before full treatment, especially for clients with sensitive skin or allergies.
Consult a physician before use if you have active acne, eczema, psoriasis, rosacea, keloid scarring, blood disorders, or are pregnant/nursing.
Keep out of reach of children. Used cartridges must be disposed of in an approved sharps container – never in household trash.
Do not adjust needle depth beyond skin tolerance. For facial use, do not exceed 0.5mm depth without professional training.
The ultra-fine 0.18mm needles reduce pain but do not eliminate it entirely. Use topical numbing for depths over 0.5mm.
Proper hygiene is critical – clean skin thoroughly with alcohol before treatment and apply sterile serums afterward.
Do not use on sunburned, irritated, or broken skin. Wait at least 4 weeks after chemical peels or laser treatments.
CE certification ensures safety standards, but user error can still cause harm. Read your Dr. Pen manual thoroughly.
