Which best selling products are great for breakouts?

COSRX pimple patches are something you want to keep in your bathroom cupboard. Easy to use, they will reduce inflammation and redness. Most of all they will create a shield on your skin to ensure bacteria is not spreading. Our top choice for an overnight treatment is COSRX Acne Pimple Master Patch

If your skin needs an extra protection during the day, COSRX Clear Fit Master Patch is more discreet. And for those difficult areas such as jawline, hairline or your back, apply COSRX AC Collection Acne Patch.
