#1 Will you get better results if you wash your face before shaving??
I do wash and lightly dry my face, which is not necessary. I do this so no dust or grime dulls the cutters. I do not shave in the shower or use a shaving foam.
#2 So is this waterproof? My husband can use it while shaving in the shower and not worry about it getting soaked?
Yes, the Philips Norelco Shaver 7100 is suitable for use in the bath or shower and for cleaning under the tap with water.
