The MediRaf is nearly pain-free, and features a non-invasive hand piece to boot! Acne scars may be deep within the dermis. Microneedling may reduce acne scarring by going further into the skin than traditional skin resurfacing devices. Though, what sets the MediRaf apart is its’ depth, power and multiple tip sizes. This allows the MediRaf to penetrate deep into the dermis without causing superficial damage to the tissue, and while precisely delivering radiofrequency energy (RF) to stimulate collagen and tighten skin.
