Treatment sessions
INFLAMMATION
Each patient received four laser treatment sessions at 14 days of interval: Nd:YAG laser on half of the face and fractional COBefore the session, the face was washed with water, and an anesthetic cream (Pridocaine cream®; lidocaine 2.5% and prilocaine 2.5%) was left for 40 min. After removing it, skin was cleansed with 70% alcohol.On one side, a long-pulsed Nd:YAG 1064-nm laser (DEKA, Synchro FT, Italy) was utilized. Lesions were treated with three consecutive overlapped passes, while the perilesional region (approximately 2 cm around the lesion) and the unaffected region (approximately 10 cm around the lesion) were treated with one pass. The fluence was 35 J/cmOn the opposite side, fractional COIce packs were immediately applied to both sides after laser treatment. Texacort 0.1% (Hydrocortisone 17- butyrate 1 mg/gm) was advised for 3 days after the session to reduce post laser inflammation. Patients were instructed to avoid sun exposure and using cosmetics or any topical or systemic medications during the study period and to apply sunscreen with SPF 50 on their whole face every day.
