As with all my other Cosrx purchases, I bought them at the recommendation of beauty blogger Joan Kim. The patches are quite inexpensive and come very well packed. You get multiple patches in multiple sizes, which is handy when you have a minor pimple that needs very small coverage. I had quite high expectations for this product, but to me it didn't live up to it's expectations. It does help getting some of the sebum out, but that's about it. You'll still have the same pimple the next day. I'm not going to be completely bashful though. Personally I like that the patches are basically invisible to the naked eye once applied on your skin, which is nice cos you can go out without looking like a fool.
