INTRODUCTION AND OBJECTIVES: Dermocosmetics have proven their benefit in acne management. However, only very few studies investigated their efficacy kinetics. This study assessed the efficacy kinetics of a dermocosmetic cream (DC) containing Punica granatum Pericarp extract, Salicylic acid, Niacinamide, Zinc gluconate, and Aqua Posae Filiformis in subjects with acne.
MATERIAL AND METHODS: 16 subjects (14 women, 2 men; mean age 29.4 ± 7.7 years; phototype II and III) with mild to moderate acne participated in a randomized, intra-individual, split-face study for 15 days. Hemi-faces randomly received DC or remained untreated. Assessments included lesion counts, acne severity, and local tolerance; subjects also rated the perceived benefit of the DC. Efficacy was also evaluated using standardized multi-modality full-face imaging and a mobile connected imaging system.
RESULTS: The inflammatory lesion count significantly (p ≤ 0.05) decreased with DC at Day 8 and Day 15; a significant decrease of the non-inflammatory lesion count was observed at Day 15 (p < 0.01). The total lesion count had significantly (p ≤ 0.05) decreased with DC at Day 8 and Day 15. Between-side differences were significant (all p ≤ 0.05) for all lesion types at D15. Local tolerance was good. Most subjects considered that their skin appearance and the visibility of acne lesions had improved.
CONCLUSION: This exploratory study provides strong evidence on the efficacy kinetics of a DC cream in acne management in subjects with fair skin tones. It shows that early, daily and specific treatment with a targeted DC significantly improves all acne lesions type, as well as acne severity as soon as 15 days.
