First off, I always use it after washing my face with my clarisonic so that it doubles as an eye moisturizer.
Second, I would think that the only interference would be if it is so thick on your lashline that the revita can't permeate. (The only active is a peptide to stimulate lash growth.) So, in theory if you always use eye makeup remover after washing, it wouldn't change, otherwise it is very thick (like an eye cream), and I would say that you would want to wash it off first.
Honestly--I can't say that the active has enhanced my lashes any more so that this is just so creamy that my lashes don't break when I'm taking my mascara off. So, washing it off you'd probably get the same lash-friendly effects.

I'd say yes, washing your face after using this product would take away from the "revitalizing" properties. What I do is wash my face first, then use this for eye makeup, go to bed and let it work its magic (love this product!). Yes it may leave some slight smudge traces when you wipe the remover off your face but if you wash your face in the morning also it shouldn't be a problem.
As for the second question, I do not think this remover contains anything that would interfere with your other lash product.
