After using Retin A cream for about 10-12 years, my skin has adapted very well to it and I have used it UNDER my eyes for years. Not near my lash line but directly under. I have always put a thin layer of Vaseline over it and have used Vaseline on my eyelids at night for years. The retin a never bothered me and has kept those krinkles at bay. Doc said as long as it doesn't burn or cause irritation it's ok but never in daytime.
Everyone is different and what May bother me may not bother you and vice versa.
