The short answer: clinic-grade microneedling hardware combines a durable, high-torque motor that holds depth and vertical entry under sustained use, fine 33G (0.20 mm) EO-sterilized single-use cartridges, adjustable depth, and genuine devices from an authorized distributor. drpenx sells authentic pens manufactured by Ekai, an ISO 13485-certified medical-device manufacturer.

What sets clinic-grade hardware apart

• Motor stability - a high-torque drive keeps needle entry vertical and consistent through back-to-back sessions.
• Durable build - made for repeated daily use rather than occasional at-home sessions.
• Fine 33G cartridges - 0.20 mm needles, EO-sterilized and single-use, fresh per client.
• Genuine and authorized - authentic hardware from an authorized distributor; the manufacturer holds ISO 13485 certification. Certificate documentation is available on request.

FAQ

What separates clinical from at-home devices?
Mostly durability and motor stability under sustained use, plus genuine cartridges. Clinic devices are built for repeated daily sessions; the needle and sterilization fundamentals (33G, EO, single-use) are the same that matter everywhere.

Are these devices FDA-registered?
The manufacturer (Ekai) is ISO 13485-certified. For regulatory status in your jurisdiction, consult your local medical-device authority.

What cartridges should a practice use?
Fine 33G (0.20 mm), EO-sterilized, single-use - a fresh sealed cartridge for every client.
