COSRX Clear Fit Master Patch is an ultra-thin acne patch in a gradient form with matt finish, and it is barely noticeable when applied on the skin. You could go out with the patch on during the daytime, and it would seem natural. It is even more invisible once makeup is applied on top. Adheres to the skin naturally, perfect for daytime use since it's even more unnoticeable under makeup. Hydrocolloid material effectively extracts impurities and creates a moist environment, which makes the healing process faster. COSRX Clear Fit Master Patch acts as a barrier against bacteria, preventing secondary infection. COSRX Clear Fit Master Patch reduces inflammation by absorbing exudate of breakouts while protecting the breakouts from secondary infection. The zit size will shrink remarkably without leaving scars after a few hours.
