Dr. Pen A7 Microneedling Pen

The right microneedling pen disappears into the treatment, letting you focus on the pass instead of the tool. The Dr. Pen A7 is built to be that steady workhorse.

The Dr. Pen A7 is a professional microneedling pen that drives single-use cartridge needles into the skin at an adjustable depth to trigger collagen induction. Practitioners set the depth to match each treatment zone across the face and body.

Collagen induction follows the controlled injury. Each micro-channel signals the skin to repair, and that repair response lays down fresh collagen and elastin over the following weeks.

The A7 uses single-use Dr. Pen cartridges, keeping every session sterile and every patient on a new needle array.

Providers run the A7 through collagen induction facials, scar work, and serum infusion when paired with a skin booster or EGF mask.
