LOL, that is embarrassing! allure had an article over the winter about emergency fixes for your face, and wouldn't you know they included what to do when you have stubble burn? i don't remember the exact directions, but i think it said to put cold milk on a washcloth (or since you're at work, a paper towel) and just let it sit on the irritated areas of your skin for a little while. that may soothe...worth a try!
Eek! That's almost as bad as wearing your hair up and realizing (when you get to work) that you have a huge hickey. Gross. At least you can let your hair down and cover that shit up. How do you hide your face? When this happens to me (hate it) I try a little aloe at night and it always looks ridiculously better in the morning. That plus a little concealer and I'm good to go. But maybe something cold will work just as well?
I'm going to try the milk thing next time. That's pretty funny it made it to the face trouble article.
I was so self conscious when I had to go to work with a bunch of small hickeys but luckily either I did a really good jump of hiding them or everyone was too embarrassed to ask what happened to my neck.
