"this is my third week of using 0.025% tretinoin cream. i am 18 years old and had always clear skin, would get the occasional zit but until the end of my junior year started noticing my skin changing. i began to get bumps on my cheeks that didn&#039;t bother me but up until my senior year i had multiple bumps little ones and big ones on my cheeks and jawline. my self esteem has gone down so much. i&#039;m a freshman in college and i have so much hope for this cream. i began peeling and my skin got irritated by the first week. it&#039;s not so bad, not sure if i&#039;m going through the purge phase, i think i am since i think i&#039;ve getting more bumps. so i really hope this works."
