I have been buying these patches for a long time and they have saved me so many times. I suffer from acne so wearing a patch over night really reduces redness and help my skin look less swollen. This product really helps with the healing process of the skin and it is very easy to use, besides it comes in different sizes which is just perfect! I will always give it five stars. This time I bought 5 pieces because I want to share with friends who also have pimples and acne problems.
