This could well be folliculitis. We had a dog with it a while back and it is definitely something you're going to want to take her to the vet for. If it is
folliculitis, she's going to need antibiotics for quite a while...
Here's the thread about Ridge's folliculitis:
Folliculitis is a deep infection of the hair follicles. It's pretty painful, so you'll want to ask for a pain med for a few days for your girl if that's what she has. You'll also want to get an Elizabethan collar from your vet to keep her from scratching at her face, which can cause scarring.
Meanwhile, though, please get her to the vet tomorrow at the latest. Keep us posted on her progress!
