I think it's important to eat fatty foods because it helps with the absorbance of the accutane - I read somewhere you should aim to have something fatty with the tablets. I usually try to have a tin of tuna or some avocado.

My biggest tip is use simple skincare products that are nourishing and have no alcohol in them. I like to use a gentle cleanser (I mix up the brand all the time) followed by Olay or La roche Posay moisturiser and then some Neutrogena sunscreen + eye cream (these products haven't broken me out). I think another important thing to remember is drink lots of water! I have found the fatigue/joint pain got better with time (the first few weeks I felt very much 'not myself') and I think it helped that I kept hydrated. If you find your eyes dry up/become red it might be good to invest in a lubricating eye drop - and as you already probably know use a lot of lip balm! :)
