My dermotalogist reccomended washing in cold water (less harsh on delicate facial skin) and to pat dry...rubbing can be too harsh & may lead to early wrinkles! I do both of these.
I use tepid water. Hot water dries the skin out which = wrinkles. I also won't shower in too warm of water...just was warm as is comfortable, for the same reason. I did 2 rounds of accutane and if Im not careful I get crazy itchy/flakey dry.
