I got an allergic reaction to my face wash - now what?

I would get some aloe vera gel that you can get in the pharmacy or supermarket & apply that, or some cool compresses. It will at least feel soothing, & can't hurt anything. Then be sure to call your Dr. tomorrow. It may have been too harsh for your face to use both. Yes, you should always read warning labels first & try a skin test on inner aspect of arm before trying a new product. Good Luck.
