I admit my advice may not be the most useful, given a) I don't shave my face and b) it's probably completely wrong, but hey, it's what I do. I tend to pick where the hair is ingrown, get all the nasty out of it, then use a pair of tweezers to pull out the ingrown hair (this can be pretty painful, I imagine - I'm a trichotillomaniac so I'm rather used to it myself!) I tend to find that, for me, it helps it heal up much faster; I use a honey shower gel as well, which is a good antiseptic (works as body wash, shampoo, antiseptic and facial cleanser all in one!) over the top, which is the other thing that makes a difference once the hair is out. Though, as I said, not sure if it's the right way to go about things, especially on your face rather than somewhere more hidden!
