"if i could give this a negative number i would. it murdered my skin. it made my skin horribly worse. i woke up the morning after my first application (which happened to be the day i was taking the sat!) with my skin just a horrible peeling, painful mess. my skin felt like there was acid under earth it. my face was disgusting, it was completely tight (it looked leathery!!!) and covered with dead skin, i couldn&#039;t see fresh skin anywhere. it was all peeling off. and burning. i, of course, stopped using it. but for the next 2 weeks my skin was peeling non stop (moisturizer and exfoliating were no help) and my face was dark red. it looked like i had had an absolutely horrible sunburn. this was after just using onexton once. wouldn&#039;t recommend."
