I honestly wasn't 100% sure how to us this product because I the instructions are completely in Korean but I put it on let it sit for little less than a minute and then begin rubbing! you will see your face slowly revealing a bright new layer. Even my scar marks have began to disappear and I only used it once! As a warning you may turn a little red when doing it but it's nothing to worry about but just to be safe test patch your hand it is a chemical peel after all.
