The Overnight Blemish Fix Everyone's Bathroom Cabinet Needs
COSRX's Acne Pimple Master Patch is a cult-favourite hydrocolloid spot patch that absorbs fluid from blemishes, protects them from bacteria and picking, and helps speed up visible healing — all while you sleep, work, or go about your day.
Each pack includes three sizes so you can match the patch to the size of your blemish, from small emerging spots to larger, more stubborn ones.
Why You'll Love It:
Absorbs & Protects: Hydrocolloid technology draws out fluid and shields blemishes from bacteria and picking.
Three Sizes in One Pack: 10mm, 12mm, and 14mm patches to suit different blemish sizes.
Discreet & Wearable: Ultra-thin, matte finish that sits comfortably under makeup or overnight.
Simple, Fragrance-Free Formula: No actives to irritate skin — just a protective barrier that does the work.
Key Ingredients & Skin Benefits:
Medical-Grade Hydrocolloid: Creates a moist healing environment that absorbs excess fluid and oil from blemishes.
How to Use:
Cleanse: Cleanse and dry the affected area completely before application.
Apply: Choose a patch slightly larger than the blemish and press firmly onto clean, dry skin.
Leave On: Leave in place for at least 6-8 hours, or overnight, replacing once the patch turns white/cloudy.
