I use it as a pre shave:
Rub the Proraso Pre into my beard
Strop my razor
Build my lather
Lather up my face
It seems to make a difference but I can't tell you what. All I really can tell you is that I tried it on a whim and got the best straight shave I had to date. So I always use it, although I've now discovered T&H preshave oil so it might just be on alternate days!
I fear no woman: except my wife, her sister and their mother!
