Treatment of atrophic scars with fractionated CO2 laser facilitating delivery of topically applied poly-L-lactic acid.
Atrophic scars represent a loss of collagen and a challenging reconstructive dilemma with disappointing traditional treatments. ⋯ The combination of using an ablative fractional CO2 laser and PLLA in the treatment of atrophic scars has a synergistic effect on their inherent properties in up-regulating new collagen synthesis to improve atrophic scars.
