I had my first chemical peel 2 days ago, and have been applying The Post-Procedure Solution by PCA Skin. After 24 hours, I began with one itchy spot on my forehead and now, 48 hours later, my entire forehead (from temple to temple) has a bumpy rash. It's not red; more skin tone, but I'm not scratching it. The rest of my face is fine. Is this normal or am I having an allergic reaction? What should I do?
