The fractional CO2 laser creates microscopic holes in the upper layer of skin and leaves the deeper part of the skin intact. The purpose of the treatment is to create controlled heat damage at the basal layer of skin leading to the reduction of wrinkles, pigmentation and acne scarring. The fractional CO2 laser also tightens and refines the skin as well as improving the long term collagen and elastin reproduction. Scope of application: 1.
