This nonsurgical, medical-grade treatment creates micro-perforations in the skin, which trigger its natural repair mechanism—which is why it's considered a natural form of skin renewal. Accelerated cell regeneration and boosted collagen production improves the appearance of the skin.Â
Microneedling treatments are done with either a derma-roller device or a smaller, more precise motorized tool, like Rejuvapen. Motorized devices are considered superior to derma rollers for several reasons: The needles puncture the skin vertically (as opposed to at a 45-degree angle), producing cleaner, more even wounds that heal quicker.
“Motorized microneedling devices are basically the same," says New York City plastic surgeon Dr. Luis Cenedese. "Variables include the number of needles per headpiece, the depth of needling, and the speed.”Â
Rejuvapen has nine microneedles in a small cylindrical cartridge. Its adjustable needle length means it can enter the skin at varying depths and speeds, to best target various layers of the skin depending on your particular skin issue.Â
Also, its disposable tip makes the procedure more sanitary, and the small cartridge makes it easier for the doctor to treat delicate areas, like around the eyes and lips.
RealSelf Tip: Most people need at least four treatment sessions to really see results. “The number of treatments you'll need depends on the level of skin damage, your skin type, and thinness—and the aggressiveness of each treatment,” says Newport Beach, California, plastic surgeon Dr. Larry Nichter.
