RESUMO
Purpose: Acne is a skin condition of the pilosebaceous unit that affects mainly the face, chest and trunk. Approximately 50% of subjects with facial acne also have acne of the trunk. This study investigated the clinical benefit of a cleansing gel containing salicylic acid 2%, zinc gluconate 0.2% and lipohydroxy acid 0.05% in truncal acne after 84 days of daily use. Materials and Methods: A single center, open label, non-randomized study with 51 subjects with mild to moderate truncal acne was conducted. Thirty-five (35) subjects completed the study; mean age was 23 years. Inflammatory and non-inflammatory lesions, Transepidermal water loss (TEWL) and local tolerance were assessed at baseline, Day 42 and Day 84 and total lesion count was calculated. Results: The total lesion count was significantly reduced (p<0.05) after 42 days (-21.5%) and 84 days (-56.3%). Non-inflammatory lesions were significantly decreased after 84 days (-64.0%) only, while inflammatory lesions were decreased at Day 42 (-29.2%), and Day 84 (-48.2%). A statistically significant skin barrier improvement was observed at Day 84 (-21.26%). No adverse events or relevant local intolerance were reported. Conclusion: The use of the cleansing gel studied was effective in improving mild to moderate truncal acne and contributed to the skin barrier improvement. The product was well tolerated.
