Microneedling pen
A motorized device with an interchangeable cartridge of multiple very fine needles that move in a rapid, repetitive vertical motion.
How it is used
Used to induce collagen through controlled microperforations of the epidermis and superficial dermis, in the treatment of scars, stretch marks, and skin aging.
Clinical tip
Penetration depth is adjustable and should be tailored to the treated area and indication, since excessive depth increases the risk of scarring.
