Does anybody have any advice for a 68 yo female who currently uses Retin A .05% and has no problem with it and has been using it for about 2 years.After taking the quiz I am definitely a border O/D R P W 31,23,37,46 guess the Florida humidity does help me. I am thinking of trying Avage or Tazorac or another one of the retinoids that are prescription only. Does anyone have any comments as to whether I should stick to what I am doing which is using the RetinA every other night or whether I might get better results with one of the others. Has anybody used Retin A and switched to another and found it to be even better?
