I have a very long struggle with acne and had heard many good things abought this product when I bought it. I was hesitant at first because I heard the high alcohol content could be irritating but luckily have no had an issue with it. Over the past couple weaks of using this as a spot treatment twice a day, I have noticed a gradual decline in my acne. Any new pimples have been smaller and healing a bit faster. It does smell like tea tree oil but I don't mind. Hope to keep seeing improvement over the weeks to come.
