I love these patches so much! This is my first time getting them in a 4 packet set, maybe I should be buying them in the 10 packet set. I love these patches very much, they make a huge difference on how my pimples develop and heal, I have little to no scarring after proper spot treatment and using these patches, I just wish the packets came with more patches, I go through these around one per month. They stay on my face while I sleep, and during the day I can wear face makeup over them and they are not very noticeable.
