Formulated with three essential ceramides Ceramide NP Ceramide AP and Ceramide EOP along with niacinamide the patches help maintain the natural skin barrier while soothing redness and irritation . The hydrocolloid technology forms a protective seal over blemishes preventing picking and shielding the skin from external aggressors which helps minimize post acne marks and supports faster healing . Additional ingredients such as cholesterol phytosphingosine and glycerin contribute to hydration and barrier repair while the fragrance free non comedogenic formula ensures suitability for sensitive acne prone skin.
