"i saw results with this product within three days! i had really bad acne on my chin and forehead and it is already almost cleared up and its only been about a month. i didnt get any redness, however after i apply it at night it burns a little bit. nothing too extreme. it also makes my skin on my chin flakey, but not on my forehead. i would not recommend stopping use of this product if you just have a mild burning sensation afterwards, because it really does work. i am so happy that i found this cream and a little really does go a long way. i only use a pea sized amount on my entire face and the tube it comes in lasts a little over a month."
