Dermalogica's Deep Acne Liquid Patch stops breakouts before you see them. Made for consumers who deal with deep cystic acne, this invisble sulfur-based treatment transforms from liquid to patch to soothe, clear, and help prevent future breakouts. 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. Proprietary TT Technology and calming Polylysine work with skin’s natural microbiome to help minimize oil. Polyphenol-rich Pomegranate extract helps smooth skin. Deep Acne Liquid Patch starts as a yellow gel that applies clear and cools on contact. It dries down to create an invisible, protective patch that acts as a semi-permeable barrier. Allowing airflow to help your blemish heal, while also protecting skin from pollution and bacteria. Deep Acne Liquid Patch is suitable for use during pregnancy and can be used at anytime, anywhere – even over make-up. Apply as soon as you feel a blemish forming.
