It's my first time trying this product after reading a lot of reviews. I have always been a skin-picker and loved popping pimples which of course isn't the best way of treating the skin. When a pimple starts forming a head then I just cleanse and put the Cosrx patch on it and leave it overnight. The following morning, patch is full of gunk and pimple is reduced in size twice. It's a great and much gentler alternative to popping pimples. Would recommend it to everyone that has acne
