If you have to wipe something off your face with water (when eating etc) will that wash away the BP? I know the I am supposed to do the regimen every 10-12 hours but I was curious do I have to avoid water or at what point after putting it on in the morning does water not negate it?

Also if I were to get something on my face while eating and then clean it with a napkin how harmful is the bacteria/aftermath for my skin? I've been trying to time the regimen right after I eat, so that I can properly wash my face afterwards however most people eat more than twice a day. I'm trying to get clearer, and I'm close to getting clear i've just got a few problem areas around my chin.
