W.Skin Laboratory AC+ Trouble Patch is a Korean spot patch for pimples and blemish-prone areas. Each pack has 56 small 10 mm patches, sized for single spots. The patches are ultra-thin and nearly transparent, so they sit discreetly on the skin and can be worn under makeup. They cover the spot, shield it from touching and picking, and help keep the area clean and protected while it calms down. They are easy to peel and apply, and reviewers describe them as comfortable, even on sensitive skin. The generous 56-piece count makes them a practical everyday blemish essential, at home or on the go.
