I don't have the slightest idea about Accutane, having never used it, so I can't speak personally to whether it increases sensitivity, etc., but still: beware of trying so many things at once that you *do* increase sensitivity, redness, papules, pustules, etc. I gently suggest taking things slowly.
Trying one new thing at a time might prove more useful in the long run - you'll have a better idea of what does what and what causes possible reactions. That's my standard advice to everyone (myself included - I've been known to try too many things at once, to my own chagrin).
I think many others have tried variations of what you're doing, so hopefully you've read up on other people's experiences & can save yourself any unnecessary duplications of effort where it won't be helpful to you.
Again, Good Luck & I hope you find an approach that works for you! Take care.
