Basic question here: What is it for? My brother gave this to me as a birthday gift last year. On the one hand, it caused me to become more interested in shaving, which led to my reading about wet shaving and acquiring a DE razor, straight razor and quality soaps and aftershaves. On the other hand, I have no idea what Proraso White pre-shave cream is supposed to acheive. It smells nice and feels nice, but does it have any practical purpose? I’m reaching the end of the jar and wondering if I want to purchase a new one. Obvioulsly I’ll find out if I miss it if I stop using it, but I notice that even on the jar it doesn’t say what the stuff is supposed to accomplish.
