Hypertrophic Scar Improvement by Early Intervention With Ablative Fractional Carbon Dioxide Laser Treatment

Ablative fractional laser treatment has been used to improve the color and texture of hypertrophic scars with safe and effective results. However, no consensus on the optimal time to initiate fractional laser treatment is available. The effect on early‐stage scars remains controversial. This study was designed to assess the efficacy and safety of ablative fractional carbon dioxide (CO2) laser treatments for hypertrophic burn scars and to analyze the efficacy and safety in the early period within 3 months after injury.
