a couple of my experiences with laser:
the red bumps, etc are worse at the beginning when the hair is more dense, especially on fleshy/fatty areas like under the jawline, at the top of the throat. It develops into something almost like acne, or at least it did for me.
The best way I found to control it:
Don't shave the day after laser. Give your skin a day or two to heal. Laser is very similar to getting sunburned, so don't do anything too harsh. If you MUST shave, go with the direction of hair growth rather than against it. Switching to a clean razor also helps.
Go easy on makeup and moisturizers, especially if they clog pores. My favorite face soap for post laser was blackhead scrub and pore cleanser by Clean and Clear. Anything with salicylic acid in it will do. Look in the "acne control" section of the drug store.
Ice!!! Because your skin reacts to laser a lot like a sunburn, ice will actually help a bit more with keeping swelling down, etc. You have to do the ice right away, waiting until the bumps show up is too late.
Cortizone cream and advil are also good ideas. And the suggestion about scheduling on Friday with a few days to heal is a good one, too.
