"i have been using tretinoin for almost 3 weeks now. first week was alright but after that my face broke out quite bad. i had quite a few new pimples on my face. ughh those two weeks tested my patience but i knew that it has to get worse before getting better so i kept that positive attitude and moved forward. now i think my face is getting used to the cream and i am not seeing any new pimples anymore. hopefully, now the &quot;clearing up phase&quot; will start. fingers crossed."
