Cosrx Acne Pimple Master Patch, 24 Patches

COSRX Acne Pimple Master Patches are the product that started the pimple patch category, using hydrocolloid, the same material used in wound dressings. The patch absorbs fluid from the spot and turns white as it does, which is the visible sign it has been working.

The underrated part is the cover itself. A patch makes it physically impossible to pick, and picking is what turns a spot that would have gone in three days into a mark that lasts three months. Three sizes are included, so you can match the patch to the spot.

Specs

• Type: Hydrocolloid pimple patches
• Pack size: 24 patches in three sizes
• Wear: Overnight or under light make-up
• Best on: Spots that have come to a head
• Brand: COSRX (Korea)

Benefits

• The barrier stops you picking, and picking is what leaves marks long after the spot has gone
• Hydrocolloid draws fluid out of the spot, which is why the patch turns white where it has been working
• Three sizes means you can use the smallest patch that covers the spot rather than a conspicuous circle
• Thin enough to wear during the day under light make-up, not only overnight
• They work on spots with a head. Deep, painful lumps under the skin need a different approach

How to Use

• Cleanse and dry the area thoroughly. Patches do not stick to damp or oily skin
• Choose the smallest patch that covers the spot completely
• Press it down and make sure the edges are sealed. Apply to bare skin, not over other products
• Leave for at least six hours, or overnight
• Peel off gently and use a fresh patch each time
• Do not use on open or broken skin. See a doctor if acne is painful, widespread or scarring
