If the lather dries on your face, just add some more lather (if you make lather in a bowl), or some more water (if you face-lather).

Use as much lather as you need, as often as you need it.

If you're nicking yourself with Glenn's edge, it's likely that you're using too much pressure. Or you could be moving the blade laterally ("slicing"), instead of moving it at right angles to the edge.

You'll work out the kinks . . .
