Summary

The scar site was divided into 3 sites; combined IPL/fractional Er:YAG laser treatment site, fractional Er:YAG laser treatment site and untreated control site. At baseline, three lesions were randomized to IPL / fractional Er:YAG laser combination therapy site, fractional Er:YAG laser treatment alone site, and untreated control site. The laser treatment was conducted total three sessions, immediately at suture removal (baseline), 4 weeks after suture removal and 8 weeks after suture removal. The evaluation of scar site was conducted 3 months later after last treatment (20 weeks after suture removal).

Conditions

• Intense Pulsed Light
• Erbium-yttrium Aluminum Garnet Laser
• Scar Prevention

Interventions

Type	Name	Description
DEVICE	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.
DEVICE	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.
