combined IPL/fractional Er:YAG laser treatment site
At baseline, three lesions were randomized to IPL / fractional Er:YAG laser combination therapy site.
Topical anesthetic cream was applied to the scar 30 minutes before laser treatment. The same dermatologist performed all laser treatments including IPL and 2,940 nm Er:YAG fractional laser. The face was cooled after treatment with gauze soaked in ice water.
The laser treatment was conducted total three sessions, immediately at suture removal, 4 weeks after suture removal and 8 weeks after suture removal. The evaluation of scar site was conducted 3 months later after last treatment.
fractional Er:YAG laser
At baseline, three lesions were randomized. Topical anesthetic cream was applied to the scar 30 minutes before laser treatment.
The same dermatologist performed 2,940 nm Er:YAG fractional laser. (long pulse mode, 1500mJ, 2Hz, 2 pass) The face was cooled after treatment with gauze soaked in ice water. The laser treatment was conducted total three sessions, immediately at suture removal, 4 weeks after suture removal and 8 weeks after suture removal. The evaluation of scar site was conducted 3 months later after last treatment.
Intense pulse light
At baseline, three lesions were randomized. Topical anesthetic cream was applied to the scar 30 minutes before laser treatment.
The same dermatologist performed IPL. (irridation energy: 12.5J/cm2, pulse duration: 10ms, 1pass) The face was cooled after treatment with gauze soaked in ice water. The laser treatment was conducted total three sessions, immediately at suture removal, 4 weeks after suture removal and 8 weeks after suture removal. The evaluation of scar site was conducted 3 months later after last treatment.
fractional Er:YAG laser treatment alone site
At baseline, three lesions were randomized to fractional Er:YAG laser combination therapy site.
Topical anesthetic cream was applied to the scar 30 minutes before laser treatment. The same dermatologist performed 2,940 nm Er:YAG fractional laser. The face was cooled after treatment with gauze soaked in ice water.
The laser treatment was conducted total three sessions, immediately at suture removal, 4 weeks after suture removal and 8 weeks after suture removal. The evaluation of scar site was conducted 3 months later after last treatment.

untreated control site
At baseline, three lesions were randomized to untreated control site. Topical anesthetic cream was applied to the scar 30 minutes before laser treatment. The evaluation of scar site was conducted 3 months later after last treatment.
