Better than Cosrx!
Absolutely love these! They work well over night and in the daytime. They adhere to the skin so well you can barely see them and they don't give off a huge shine in the light so it's like a second skin. The only 'negative' I can think of is the removal can leave a sticky layer on the edges of where the patch was, but you should bebwashing your face anyway.
