Hi,

I have been prescribed isotrex gel as retin-a has been discontinued in the UK. My doc said apply it twice a day which I know is incorrect, I know people say start off slow and gradually build your tolerance up. So would you do it say 3 times a week for the first 3 weeks and then daily thereafter? And do you ever apply moisturiser on top as sometimes it leaves my skin tight?

And does it matter whether it is applied straight after you have washed your face or should you wait 20 minutes?

Sorry for all the questions!
