A randomized guinea pig study on external cell growth factors after fractional ultrapulsed CO(2) laser therapy.

Background And Objectives: The Fractional Ultrapulsed CO2 laser has been successfully used in treating fine wrinkles, acne scars, and photoaged skin. However, the downtime typically lasts a week or more. The purpose of this study was to observe the efficacy of external cell growth factors after Fractional Ultrapulsed CO2 laser therapy.
