Korean skincare for whatever pops up: a thin, translucent hydrocolloid patch that goes on in seconds and stays discreet day or night. Press one onto a clean, dry blemish and leave it on for 6 to 8 hours for visible results. Hydrocolloid draws out impurities and protects the spot while it works. Salicylic acid helps clarify, while niacinamide (vitamin B3) and silk ferment help condition skin so it isn't left dry. With 224 patches in every pack, you're stocked for every breakout to come.
