Search for a microneedling pen and you'll find dozens of options, from very cheap unbranded devices to professional-looking pens with long spec lists. It's not always easy to tell what matters. This checklist covers the features worth paying attention to, the red flags to avoid, and the questions to ask before you buy.
The short answer: look for adjustable depth that covers home-use settings, several speed options, a cordless design, sterile individually sealed single-use cartridges in a range of sizes, clear guidance, UK-based support and a fair guarantee. Avoid pens with unclear cartridge sourcing, no instructions, or claims that sound too good to be true.
The buyer's checklist
1. Adjustable depth
You'll use different depths for different areas: around 0.6mm for the face and neck, 0.6mm to 1.0mm for the scalp, and 1.0mm to 1.5mm for the body. A pen with a clear, easy-to-read depth adjustment covering these ranges lets you use one device everywhere. Be wary of very deep settings marketed for home use on the face.
2. Speed settings
Several speeds let you start gently and adjust for comfort. Five settings gives plenty of flexibility.
3. Cartridge quality and range
This is one of the most important factors. Look for:
- Sterile, individually sealed, single-use cartridges
- A range of sizes, from a small head for individual marks to larger heads for the scalp and body
- A nano option for gentle surface work and around the eyes
- Reliable availability, so you can keep buying them
- A clear fit for your specific pen
Cartridges with a built-in barrier help stop serum flowing back into the pen, which keeps things more hygienic.
4. Cordless design and battery
A cordless pen is easier to move around the face, scalp and body. Look for enough battery life to finish several sessions per charge, and convenient charging such as USB-C.
5. Weight and grip
A lightweight, well-balanced pen is easier to hold steady at 90 degrees, which gives more even results.
6. Clear guidance
Good instructions and guides on depth, technique, frequency and aftercare make a real difference, especially if you're new.
7. UK support, returns and warranty
A UK-based brand with responsive support, a clear returns policy and a warranty gives peace of mind if something goes wrong.
8. Honest claims
Microneedling is a cosmetic procedure. Be cautious of brands promising to "cure" or "treat" skin or hair conditions, or showing results that look too good to be true.
Red flags to avoid
- Cartridges that aren't individually sealed, or with no sterility information
- No instructions, or instructions that suggest very deep facial depths at home
- No UK contact details, returns policy or warranty
- Medical claims, such as "cures hair loss" or "removes scars permanently"
- Prices that seem far too low for the features offered
- Cartridges that are hard to find or only sold by third parties
