COSRX Acne Pimple Master Patch 24 pcs

COSRX Acne Pimple Master Patch is the best-selling hydrocolloid patch in Korean skincare, and it works through simple wound-care science rather than any active ingredient.

Hydrocolloid draws fluid out of a blemish that has come to a head and holds it in the patch — you can see the white circle that forms overnight. Just as importantly, it creates a physical barrier that stops you touching or picking, which is what turns a spot into a scar.

The sheet carries three sizes (10 mm, 12 mm, 7 mm) so you can match the patch to the blemish.

How to use: on clean, dry skin with no product underneath, press a patch over the blemish. Leave for at least six hours, or overnight. Replace if it turns fully white.

Count: 24 patches

Frequently asked questions

Do they work on blind pimples under the skin?
No. Hydrocolloid only draws out fluid that is near the surface. On a deep, closed bump there is nothing for it to absorb.

Can I wear them during the day?
Yes — they are thin and matte. You can apply light makeup over them, though it is cleaner to wear them at night.

Why did mine not turn white?
Either the spot was not open or ready, or a serum or moisturizer underneath stopped the patch sticking. Apply to bare, dry skin.
