I use the white as a pre and post.

After wetting my face and giving it a wash, I'll rub in some white Proraso taking my time on it, lather up then shave. Once I'm acceptably smooth I'll rub it in again quite well though more gently and finish with cold water to the face.

Am I the only person that opens the lid and submerges my Proraso in the hot water? It doesn't seem to loosen or contaminate the water and when it's slightly warm/wet it rubs in really nicely, plus it doesn't give the cold feeling against the face you've just spent minutes heating up.
