Abstract

Background
Acne vulgaris is a chronic inflammatory disease of the pilosebaceous unit. Adapalene-benzoyl peroxide gel has been proven to be effective in the treatment of both inflammatory and comedonal acne. However, skin irritation characterized by erythema, scaling, and dryness may occur with the use of this formula.
Objective
This study aimed to investigate the effects and safety of a new formulation of adpalene-benzoyl peroxide in combination with multi-lamellar emulsion (MLE) for acne treatment. Methods: All patients were treated with adapalene-benzoyl peroxide with MLE once daily for 12 weeks on acne lesions. The subjects visited the hospital at baseline, 2 weeks, 4 weeks, 8 weeks, and 12 weeks, and clinical effects, patient satisfaction, and adverse effects were estimated. The severity of adverse effects was measured on a 4-point scale.
Results
A total of 30 subjects were enrolled. The number of lesions decreased significantly from 20.2 to 7.8 (p＜ 0.0001) after treatment. Investigator’s global assessment showed almost clear, and patient satisfaction increased from 3.57 to 4.13. The subjects had adverse effects such as tingling sensation (83.3%), scales (80.0%), erythema (63.3%), and dryness (63.3%). Severity of adverse effects had 1 point on average. Additionally, transepidermal water loss was found to be decreased.
Conclusion
This study suggests that adapalene-benzoyl peroxide with MLE is effective for treating acne lesions and shows high patient satisfaction. Hence, this new combination could be a safe and well-tolerated option for acne treatment.
