These are replacement nano cartridges for the Dr. Pen HydraPen H3 Pro, supplied in a pack of 10. Nano tips don't pierce the skin the way a needle cartridge does — they create micro-channels at the surface, which makes them the gentlest option in the range and the one most often used for serum infusion and for skin that can't tolerate deeper treatment.
Cartridges are single use only. Open a new one for every treatment and dispose of it afterwards. If you're unsure which cartridge suits your treatment, our cartridge guide and cartridge comparison chart walk through every pin count and nano option.
About the HydraPen H3
The HydraPen is a containable-cartridge device: serum is held in the cartridge and released into the skin automatically as you work, so you don't have to stop and reapply. That improves both the consistency and the efficiency of the treatment.
Features
- Containable needle cartridge — automatic serum application, clean and hygienic
- Works with a range of serums
- LED speed display
- Comfortable handheld design with built-in battery for wireless operation
- Adjustable needle length: 0.25mm, 0.5mm, 1.0mm
- Four-level speed control, 1,800–7,000 RPM
- H12, HS Nano and HR Nano tips using 30-gauge acupuncture needles to reduce discomfort
- Digital motor in the handpiece, aluminum housing
