Ablative fractional lasers such as the UltraPulse Encore by Lumenis are extremely effective for treating acne scars. The laser will treat a “fraction” of the skin by creating thousands of tiny perforations, whilst leaving undamaged skin intact. These undamaged cells move into the “damaged area”, and heal the wounded area. The injury to the damaged skin causes collagen stimulation.
Further collagen remodelling takes place for 3-6 months and the number of treatments will depend on the severity of the acne scars and how your skin reacts to your laser skin resurfacing treatment but usually 3 treatments are required.
