Hi- I'm on an Accutane course and after I finish, I'd like to start a retinoid. I've heard it's smart to start with a more gentle retinoid, like Differin, and let your skin get used to it. However, if I've been using Accutane would that mean it would be easy for my skin to handle the stronger retinoids like Retin A, without easing into it with Differin? My skin is a little on the sensitive side but I'd like to eventually use Retin A for fading red marks and wrinkles (I'm 25). Thanks!
