Reduction of atropic acne scars by microneedling with radiofrequency . As you might see, there is no bruising or bleeding, as one might expect from other microneedling devices.
So how does this work?
The gold plated needles go through the skin and release radiofrequent energy, which in turn regenerates collagen and tighten the skin, and this will eventually reduce deep wrinkles and scars. It is even safe for darker skin types - unlike most of the acne scar laser treatments.
