hi guys. i've been using retin-a .025% on my face and body for almost two weeks now (i apply it, wait an hour/30 mins, then apply hq 4%). i don't buffer it and i haven't had any peeling on my face or body, but i've had some skin tightness on my neck in the previous few days.
today, a few hours after applying retin-a, the skin on my neck has an itchy red rash. has anyone experinced this? what are your thoughts? should i put hydrocortisone on it to help with the itchiness?
also, is it normal to have no peeling after a few days short of two weeks?
thanks!
