As the Rejuvapen treats your skin, it creates micro-point punctures in the skin. This is perceived by the body as damage, which stimulates the release of growth factors that trigger the production of collagen and elastin. Your skin reacts to any injury by initiating the healing process. Your skin normally assumes that scars, stretch marks and wrinkles are repaired, but with micro needling treatments, the skin is tricked into repairing itself and to produce more collagen and elastin.
The process of micro needling skin remodeling can go on for months after each microneedling treatment. Results can be seen within a week to a few months. Your skin naturally heals itself every 45 days, so with microneedling stimulation changes can be dramatic and fast.
