COSRX Acne Pimple Master Patch is a clinically-proven hydrocolloid spot treatment designed to address whiteheads and surface-level pimples with precision and speed. Each ultra-thin patch adheres securely to skin, creating a protective, moisture-retaining barrier that draws out impurities while shielding the blemish from bacteria, dirt, and irritation.

The 24-pack ensures you always have patches on hand for sudden breakouts, making this an essential part of an active acne-management routine. Apply to clean, dry skin over a whitehead and leave overnight or throughout the day—the patch visibly reduces inflammation, absorbs exudate, and accelerates healing, often showing results within 6–8 hours of use.
