For a hydrocolloid patch to work effectively, it needs to adhere directly to the skin. Our Triple Action Pimple Patches work best when applied immediately after using our BHA cleanser. This ensures the pore is open and free of surface oils, allowing the patch to create a perfect vacuum seal. This "clean-start" method maximizes the amount of impurities the patch can draw out overnight. Achieve the most satisfying results by prepping your skin correctly before you patch. Hygiene is the key to clarity.
