It seems to me that you have experienced a severe local allergic reaction.
Did you call your doctor?
Do you still have sores on your face?

yes definately sounds like an allergic reaction to me. You should never apply hair removal creams to your face as it is the most sensitive and may leave stain marks after the red sores disappear. Its no big deal if you've applied it once, but if its geting worse, you should see your dermitologist asap
