The COSRX Acne Pimple Master Patch is a cult-favorite K-beauty skincare staple designed to speed up the healing process of active breakouts while keeping skin protected.

What It Is

These are thin, clear hydrocolloid patches that adhere directly to the skin. They act as a physical barrier against bacteria and your own fingers (perfect if you are tempted to pick at blemishes) while actively absorbing impurities overnight.

Key Benefits

• Accelerated Healing: The hydrocolloid material acts like a sponge, drawing out gunk, oil, and exudate (pus) from whiteheads and inflamed blemishes.
• Reduces Scarring: By keeping the area moist and preventing picking, it drastically reduces the chances of dark spots, hyperpigmentation, and scarring.
• Invisible & Secure: The medical-grade adhesive stays put even if you toss and turn at night, and its translucent finish makes it low-profile enough to wear during the day.
• Non-Drying: Unlike harsh topical spot treatments, these patches flatten pimples without drying out or flaking the surrounding skin.

What’s Inside the Pack

Each resealable pack contains a single sheet with 24 round patches broken down into three convenient sizes to match the size of your blemish:

• Small (7mm) – 10 patches
• Medium (10mm) – 5 patches
• Large (12mm) – 9 patches

How to Use

1. Cleanse and Dry: Wash your face thoroughly. Crucial step: Ensure the target area is completely dry and free of any lotion, serum, or moisturizer, otherwise the patch will not stick.
2. Apply: Select a patch slightly larger than the blemish, peel it off the film, and press it directly over the pimple.
3. Let it Work: Leave it on for several hours or overnight. You will know it is ready to be removed when the center turns a cloudy, opaque white—signaling that it has successfully absorbed the impurities. Remove gently and replace with a fresh one if necessary.

Skin Type Note: Ideal for all skin types, especially those prone to whiteheads, surface-level blemishes, and hormonal breakouts. (Note: These are less effective on deep, cystic, under-the-skin acne that hasn't come to a head yet).
