Efficacy of MAS063DP lotion vs 0.02% triamcinolone acetonide lotion in improving post-ablative fractional CO2 laser resurfacing wound healing: a split-face, triple-blinded, randomized, controlled trial

Abstract

Proven as effective acne scar treatment, ablative fractional carbon dioxide (AFCO₂) laser requires post-laser wound healing care. MAS063DP is a multicomponent nonsteroidal anti-inflammatory moisturizer for effective post-laser treatment. This study compares the efficacy of MAS063DP and 0.02% triamcinolone acetonide (TA) lotion for post-laser wound healing and complications. A split-face, triple-blinded, clinical study was performed in 16 patients, aged 20–50 years, receiving AFCO₂ on both sides of the face, with MAS063DP on one side and 0.02% TA on the other side for 7 days twice daily. Digital photography, hemoglobin, and melanin index at baseline were obtained immediately after laser treatment and then at days 3, 5, 7, and 30. Erythema, edema, crusting, adverse effects, and post-inflammatory hyperpigmentation (PIH) were followed every visit. Sixteen patients, mean age 38.6 (8.4) years, with moderate–severe atrophic scar and skin phototype III–IV completed the study. Clinical improvement of edema, erythema, crusting, and hyperpigmentation was observed from day 3 to day 30 (P < 0.001), with no statistically significant difference in both groups. There was also no statistical difference of hemoglobin, melanin index, and texture at days 3, 5, 7, and 30. Melanin index at day 30 was significantly less than baseline in both MAS063DP and 0.02% TA. With PIH in 50% of cases, both treatments demonstrated good safety profiles and no serious adverse reactions. MAS063DP could be an effective treatment for post-laser wound healing and complications, compatible to 0.02% TA.
