COSRX Clear Fit Master Patch is a Korean ultra-thin hydrocolloid acne patch engineered for daytime use. Each pack contains 18 patches measuring 10mm x 10mm and just 0.12mm to 0.14mm thick, with a matte gradient finish that sits virtually invisible on skin — and even more so under makeup. Made with the patented SomadermSpot-S hydrocolloid material, it absorbs breakout fluid, blocks bacteria, and accelerates healing without touching or picking the spot.
