I use a little on my neck as added protection especially if I've not just stepped out of the shower.
Also, if i'm against the clock as it where then I use it all over before the soap as it pretty much garrentees no nicks or weepers no matter how ham fisted I'm being.
I've used a few, currently using Nuage I picked up in sainsburys for £1, for my purposes its as good as somersets and king of shaves. Oddly I picked it up because it was cheap (good reason) and it shares its name with a hell hole nightclub I used to frequent back in the day in Dover (bad reason).
