I had done some research and found out that this supplement is supposed to be good for allergies. I decided to give it a try. I took 2 yesterday as the directions said and a few hours later, my neck and sides of my face were red and itchy. I have a rash on the back of my neck. I'm still itching today. I will not take anymore of this supplement again. It's supposed to help allergies, but actually induced an allergic reaction for me. Now I'm taking benadryl and hoping this allergic reaction does not last long.

Opalescence 35% is sold in dental offices. I've been whitening weekly with it for over six years. Caution: Use this only with custom tooth trays made by your dentist (or your clear retainers if you have those). Reason: You do NOT want this getting onto your gums.
