I use retin-A at night but not every night. I have to be careful not to put it near my eyes because it irritates them, but otherwise, it works well. I don't exfoliate except maybe twice a month.

I'd like to add a Vit. C product for daytime. What do you recommend? Any other recommendations?

Derm. told me I have very strong skin. I used to sunbathe like mad and also used a sunlamp for acne when I was younger - didn't know any better and thank god my skin is still in one piece and looks very well for my age. I also smoked for a few years. I'm very lucky that my skin looks as well as it does - must be genetic.
