"what an amazing product. i have struggled with acne for about 10 years (now 22), my entire t-zone has always had blackheads which (although not good for the skin) i have been extracting almost every second day. it has made me extremely frustrated that no matter how much money i spend on keeping my skin healthy, it was always a temporary fix. i wanted an alternative to the pill as i was terrified of the side effects it came with. the doctor gave me duac. i have been using this product every night (after i moisturize) and i am now on my fifth day - all of my blackheads are gone. don&#039;t ask me how! i have not had any peeling, dryness, redness or burning. there is only a small tingling sensation when applied. this is a lifesaver of a product."
