What Are Dermapen 4 Replacement Cartridges?
A Dermapen 4 replacement cartridge is the disposable needle head that attaches to your Dermapen 4 device for each procedure. Every cartridge contains 16 ultra-fine needles — the revolutionary cartridge configuration designed specifically for the Dermapen 4 system:
- 33-gauge, medical-grade stainless steel needles — fine enough for comfortable facial and sensitive-area work, robust enough for deeper body and scar treatments
- Gamma-sterilised and individually sealed — each cartridge is sterile, single-use, and hygienically packaged for one procedure per patient
- RFID-compatible — the Dermapen 4's built-in RFID technology automatically recognizes genuine Dermapen 4 cartridges and calibrates the device for precise, drag-free penetration; non-genuine cartridges will not calibrate correctly
- Clinic-proven technology — the same 16-needle cartridge technology used in professional clinics worldwide
The 16-needle configuration is engineered to be the ideal balance of treatment intensity, coverage speed, and patient comfort: more micro-channels per pass for efficient collagen induction, a smooth glide with noticeably less pain, and clean vertical insertion that minimizes unnecessary skin trauma.
Dermapen 4 Cartridge Types Explained
The Dermapen 4 uses a single, unified 16-needle cartridge system — there are no alternative pin configurations to select for this device. Unlike some other microneedling brands that offer multiple needle types for one device, the 16-needle cartridge is the single standard engineered for all Dermapen 4 procedures. This simplifies ordering and training: one cartridge type fits every treatment.
What varies is the packaging size, which affects your inventory management and reorder convenience:
| Cartridge format | Contents | Best for |
|---|---|---|
| Multi-pack (16 Pins for Dermapen 4) | Gamma-sterilised, single-use 16-needle cartridges in bulk | Busy clinics and professionals running procedures regularly — fewer reorder interruptions |
| Smaller pack (manufacturer packaging) | Gamma-sterilised, single-use 16-needle cartridges in small quantities | Practitioners starting out, verifying workflow, or carrying minimal clinic inventory |
Key facts about Dermapen 4 cartridges:
- One needle type, one standard — the Dermapen 4 accepts only genuine 16-needle cartridges; no 12-pin, 18-pin, or 36-pin alternatives are available or compatible
- Always single-use — each cartridge is designed for one procedure per patient; never reuse or re-sterilise
- RFID-verified authenticity — the device only calibrates for genuine Dermapen cartridges, protecting treatment quality, consistency, and patient safety
- Universal across treatments — the same 16-needle cartridge works for facial rejuvenation, scar revision, scalp treatments, and body procedures; depth and speed are adjusted on the device, not by changing the needle
16-Pin vs Other Needle Configurations: What's the Difference?
Because the Dermapen 4 is a closed cartridge system, it is helpful to understand how its 16-needle cartridge compares with the configurations used by other microneedling pens — especially if you also use or are considering other devices.
| Feature | 16-pin (Dermapen 4) | 18-pin (Dr.Pen A11 / M8S) | 12-pin (fine-needle type) | 36-pin (high-density type) |
|---|---|---|---|---|
| Typical needle gauge | 33G ultra-fine | Standard | Ultra-fine | Fine |
| Channel density per pass | Balanced — efficient coverage + comfort | Moderate | Lower density, finer points | Higher density, more channels |
| Best suited for | All Dermapen 4 treatments: face, scars, scalp, body | General microneedling, adjustable speed/depth | Sensitive or delicate areas | Broad surface coverage |
| Compatibility with Dermapen 4 | Yes — the only compatible type (RFID-verified) | No | No | No |
| Usage | Single-use, one procedure | Single-use | Single-use | Single-use |
The practical takeaway: if you own a Dermapen 4, you only ever order 16-needle cartridges. If you own a Dr.Pen or another device, you need that brand's cartridge — Dermapen 4 cartridges are not interchangeable with Dr.Pen or other third-party cartridges, and the RFID system will not recognize them anyway. When stocking supplies, check the device model first to avoid buying the wrong needle type.
How to Choose the Right Dermapen 4 Cartridges
Choosing the right Dermapen 4 cartridges comes down to four considerations: quantity planning, hygiene requirements, authenticity, and pack format.
1. Match quantity to your procedure volume
- Estimate cartridges per session. A standard facial treatment typically uses 1–2 cartridges depending on treatment area and protocol; full-body or scalp procedures may use additional cartridges.
- Plan around treatment courses. Most microneedling protocols run in a series (typically 3–6 sessions spaced 4–6 weeks apart). Multiply sessions by cartridges per session to size your order.
- Buy in bulk for continuous practice. Running procedures regularly? A multi-pack eliminates mid-week stockouts and minimizes reorder frequency. Low-volume practitioners can start with a smaller pack to validate workflow.
2. Always use sterile, single-use cartridges
- Every genuine Dermapen 4 cartridge is gamma-sterilised and individually sealed. Open a fresh cartridge for every patient and dispose of it after the procedure.
- Never reuse or attempt to re-sterilise a cartridge — single-use design is a core part of the Dermapen 4's anti-contamination safety standard.
3. Verify genuine cartridges
- The Dermapen 4's RFID system recognizes and calibrates only genuine Dermapen cartridges. If a cartridge is not recognized, the device will not operate at calibrated performance — always source from authorized suppliers.
- Purchase from trusted channels (such as the official store link on this page) to guarantee authentic, RFID-compatible cartridges.
4. Choose the pack format that fits your workflow
Cartridges are available in different pack sizes. If you run treatments continuously, a bulk multi-pack keeps your supply stocked and reduces reorder frequency; if your volume is low, a smaller pack is sufficient. Either way, always order genuine cartridges from an authorized supplier.
How Often Should You Replace Dermapen 4 Cartridges? Storage Basics
Replacement frequency
- One cartridge = one procedure. Replace the cartridge for every patient and every session. There is no "reuse count" — the cartridge is designed for a single use to guarantee sterility and consistent needle sharpness.
- Estimate your annual volume. For example, 10 facial treatments per month at ~1.5 cartridges each ≈ 15 cartridges/month ≈ 180 cartridges per year for a busy solo practitioner.
- Check the expiry date before each use and discard any cartridge past its expiry.
Storage basics
- Store sealed cartridges in a cool, dry place away from direct sunlight and moisture.
- Keep cartridges in their original sterile packaging until the moment of use.
- Discard any cartridge with damaged or opened sterile packaging.
- Do not store near heat sources, and keep out of reach of children.

Dermapen 4 Cartridges FAQ
Which cartridges does the Dermapen 4 use?
The Dermapen 4 uses the revolutionary 16-needle cartridge system: 16 ultra-fine, 33-gauge, medical-grade stainless steel needles, gamma-sterilised and single-use. This is the only cartridge type compatible with the device.
How often should I replace Dermapen 4 cartridges?
Every cartridge is single-use — replace it for every patient and every procedure. Never reuse a cartridge; each one is designed for one treatment to guarantee sterility and consistent needle performance.
Can I use Dr.Pen or other third-party cartridges on the Dermapen 4?
No. The Dermapen 4 is a closed system designed exclusively for genuine Dermapen 16-needle cartridges. Its RFID technology recognizes and calibrates only authentic Dermapen cartridges, so Dr.Pen, generic, or other third-party cartridges will not work correctly and should not be used.
Are Dermapen 4 cartridges compatible with Dr.Pen devices?
No. Dermapen 4 cartridges are designed for the Dermapen 4's cartridge system and connector. If you use a Dr.Pen device, you need Dr.Pen cartridges — check your device model before ordering.
How many cartridges do I need per treatment?
A standard facial treatment typically uses 1–2 cartridges depending on the protocol and treatment area. Body or scalp procedures may require additional cartridges. Plan for a typical course of 3–6 sessions spaced 4–6 weeks apart.
How do I know my Dermapen 4 cartridges are genuine?
Genuine Dermapen 4 cartridges are RFID-tagged and recognized automatically by the device — if the device does not calibrate to a cartridge, it is not a genuine Dermapen cartridge. Buy from authorized suppliers only to guarantee authenticity, sterility, and calibrated performance.
Can I reuse a cartridge if it looks clean?
No. Cartridges are single-use by design. Reuse compromises sterility and needle sharpness, and it violates the Dermapen 4's anti-contamination safety standard. Always use a fresh cartridge for each patient.
How should I store Dermapen 4 cartridges?
Store sealed cartridges in a cool, dry place away from direct sunlight and moisture, in their original sterile packaging. Discard any cartridge with damaged packaging or a passed expiry date.
Is buying cartridges in bulk worth it?
For any practice running regular treatments, yes. A bulk multi-pack removes the need for frequent reordering and ensures you never run out mid-week. Smaller packs are suitable for very low-volume use.
Do Dermapen 4 cartridges fit the Dermapen HOME or myDermapen devices?
The 16-needle cartridge technology is the same used in professional clinics. Per the manufacturer's official guidance, these cartridges are not suitable for myDermapen — always confirm device compatibility before purchasing.
Can the same cartridge be used for different treatments (face, scalp, body)?
Yes. The 16-needle cartridge is universal across Dermapen 4 treatments — facial rejuvenation, scar revision, scalp, and body procedures all use the same cartridge. Depth and speed are adjusted on the device itself, not by changing the needle.
Do cartridges expire?
Yes. Check the expiry date printed on the packaging before use and discard any cartridge past its expiry, even if the packaging appears intact.
