Tretinoin
"I been using tretinoin 1%  for 2 weeks now, acne prone skin applying only at night with my favorite night cream. Yes my face peeled ALOT only for few days till my skin got used to it but might I say oooh my gosh what difference! Be patient it really works..keep applying your favorite cream in between to keep skin moist. Peeling will stop after first few days, my skin peeled so much but loved results. Remember peeling skin means new healthy skin! "
