Acne Hydrocolloid Patches Acotye come with 140 ultra-thin and matte hydrocolloid patches for the day, and 70 hydrocolloid patches for the night, evenly distributed in sizes of 8 mm, 10 mm, 12 mm and 14 mm. Both versions vary in terms of thickness and transparency. The anti-acne patches for the day are 0.25 mm thick and offer additional adhesion, with a clear and matte finish that blends with all skin tones. The anti-acne patches for the night are 0.4 mm thick for better absorption and to prevent them from falling off during the night, even when moving. The acne healing patches contain salicylic acid, which eliminates bacteria and impurities and reduces the appearance of redness. Niacinamide improves skin texture and tone, while hyaluronic acid is an excellent moisturizer that retains moisture. The Anti Pimple Acne Patches have super absorbent properties and easily remove pus from whiteheads. First, clean the inflamed area with a cleansing wipe, then leave it on for at least 6 hours (or overnight) to reduce swelling, redness, and the size of pimples.
