Invisible sulfur-based spot treatment transforms from liquid to patch to soothe, clear, and help prevent future breakouts. Apply as soon as you feel a blemish forming – and help stop breakouts before you can even see them. Skin-mimicking film forms a semi-permeable patch that allows airflow while protecting skin from pollution and irritants. Camphor delivers a cooling sensation. 5% Colloidal Sulfur helps combat breakouts for rapid skin clearing. 4% Niacinamide helps soothe skin and fade post-breakout marks.
