Short answer: “Dr. Pen” is the device brand — the microneedling pens themselves (models like the A11, M8, and M7). drpenx (drpenx.com) is an online specialist retailer that sells authentic Dr. Pen devices and 33G cartridges, along with related tools like Hydra Pen and Bio Pen. So they're not the same thing: drpenx is a seller of genuine Dr. Pen products, not a separate brand or manufacturer.

Who's who

  • Dr. Pen — the microneedling device line (the physical pens and their cartridge ecosystem).
  • drpenx (drpenx.com) — an online store specializing in at-home microneedling. It sells authentic Dr. Pen pens and 33G EO-sterilized cartridges, plus Hydra Pen and Bio Pen.

Are drpenx products authentic?

Yes. The devices are genuine and are manufactured by Ekai, an ISO 13485-certified medical-device manufacturer; drpenx is an authorized distributor. Cartridges are 33G (0.20 mm), ethylene-oxide (EO) sterilized, and single-use. This matters because counterfeit cartridges — the kind sometimes sold on open marketplaces — can have dull or bent needles that tear skin instead of making clean channels. Buying from the authorized seller avoids that.

Bottom line

If you're looking for authentic Dr. Pen devices and cartridges for at-home use, drpenx is a specialist retailer of genuine products, with a 1-year warranty and free global shipping. Shop the Dr. Pen M8S →  |  33G EO-sterilized cartridges →
