"My friend was on it a few months before me and I saw her skin clear in about 3 weeks. I was looking forward to the same thing happening to my skin. Unfortunately, my acne got MUCH worse!!! For a little more than 2 months my skin showed no sign of improvement and I wanted to give up. My mom told me to hang in there for one more month, and I&#039;m glad I did. After about 2 and a 1/2 months, my skin just began clearing. And once I started noticing a difference, all pimples were gone in a week. Dry lips were hardly there thanks to Aquaphor. DO NOT PICK at your face. No matter how many people told me not to, I did it anyway and have scars. Also, Cetaphil lotion is a blessing. Back pain started around month 3 but its a small price to pay."
