Acne medications are a common source of facial dryness resulting in skin barrier damage and poor patient compliance. Retinoids and benzoyl peroxide are some of the most frequently prescribed and effective acne medications, however, dryness is an unwanted side effect. A new acne medication, 1% clascoterone, has been placed in a novel vehicle for excellent drug delivery in combination with excellent barrier properties. The barrier properties of 1% clascoterone have never been demonstrated. This study is aimed at better understanding the positive barrier effects of 1% clascoterone.
