Disposable A7 Dermapen Needle Cartridges for Microneedling Therapy - Anti-Aging & Skin Rejuvenation

You're looking at the A7 cartridges, and the first thing you'll notice is the range of needle configurations—form 1 needle for precision work up to 36 for coverage, plus the nano, 3D, and 5D heads that some clinics really prefer for specific protocols.

Most buyers go with the 7-needle cartridge for general face work, and we usually have stock on the 0.5mm, 1.0mm, and 1.5mm lengths in that config, but the 2.5mm is something you'll want to check lead time on (usually 2-4 weeks).

They're gamma sterilized, so you can open the pack and go without worrying about contamination, and the medical-grade stainles steel holds up better than some cheaper alternatives I've seen—it doesn't dull as quickly if you're doing multiple passes on one cartridge.

We ship them in boxes of 20 pieces minimum, and the shelf life is three years from manufacture date as long as you keep them in a dry room-temperture spot, though I've seen them perform fine even a month or two past that for personal use.

One thing people don't always ask about: the nano cartridges are actually better for clients with very sensitive skin or for superficial work, but they're not suited for deep scar revision—you want the 36-needle or 1-needle for that, depending on the technique.

Anyway, each cartridge is compatble with the A7 series dermapen, so if you've got one of those devices, you're good to go with full range of treatments from face and neck down to the body, but I'd avoid the 2.5mm on the décolletage unless you're really experienced.
