Cosrx Acne Pimple Master Patch (24 Patches)

Cosrx Acne Pimple Master Patch is the world's best-selling hydrocolloid acne patch — a thin, transparent sticker that absorbs pus and impurities from blemishes while protecting them from bacteria, dirt, and picking. The hydrocolloid material creates a moist healing environment that speeds recovery and reduces the risk of scarring.

Each pack contains 24 patches in 3 sizes (7mm, 10mm, 12mm) to fit any blemish. The ultra-thin design is virtually invisible on skin, making it wearable during the day or overnight. Simply apply to clean, dry skin over a whitehead or popped pimple and leave until the patch turns white — that means it's absorbed the impurities.

1. Cleanse your face and dry the blemish area thoroughly.
2. Select the appropriate size patch for your blemish.
3. Peel and apply sticky side down directly onto the pimple.
4. Press gently to secure adhesion.
5. Leave on until the patch turns white (6-8 hours or overnight).
6. Peel off gently and discard. Apply a fresh patch if needed.

Pro tip: These patches work best on whiteheads and pimples that have come to a head — they're designed to absorb the fluid. Apply on completely clean, dry skin BEFORE any skincare products (toner, serum, moisturiser) for maximum adhesion. If you apply over products, the patch won't stick properly. Change patches between showers. The patch turning white is the signal that it's done its job — the white material is the absorbed impurities. Keep a pack in your bag for emergency breakout treatment.
