A 2.6% Benzoyl Peroxide AV Cleanser Specifically Designed for Sensitive Skin Offers Good Efficacy and Tolerability.

Background: Mild-to-moderate acne vulgaris (AV) is common among adults, and benzoyl peroxide (BPO) has a long history of efficacy in reducing AV lesions. The efficacy of BPO is comparable for concentrations from 2.5% to 10% used as leave-on therapy, but tolerability is usually best at lower concentrations formulated in well-designed vehicles and with newer formulation methods such as micronization. This study assessed the efficacy and safety of a 2.6% BPO cleanser (Complexion Clearing AV Cleanser, CCAC) in mild-to-moderate AV.

Methods: This was a single-center, open-label, 4-week study of subjects aged 18 to 45 years (n=28) with self-perceived sensitive skin and mild-to-moderate AV. CCAC was applied twice daily (morning and evening) on damp skin. Assessments included lesion counts, clinical photography with porphyrin analysis, patient self-assessment questionnaires, collection of adverse events, and standard tolerability ratings.

Results: Total lesion counts were significantly reduced by week 1 of CCAC cleanser use (-25.2%, P<0.05). At week 4, AV lesions were numerically reduced but did not reach statistical significance. Additionally, there was a significant reduction of porphyrin counts at week 1 (-19.4% right side face, -28.8% left side, P<0.05 vs baseline). CCAC was well tolerated, with no significant increase in tolerability ratings at any time point compared to baseline, and patients reported good satisfaction.

Conclusions: CCAC was efficacious in reducing AV lesions in as little as one week, and a trend in reduction was shown through week 4. Additionally, this 2.6% BPO cleanser was also shown to be very well tolerated and well-liked by subjects with self-perceived sensitive skin.
