But again, real acne caused by food doesn't give you burnt skin and leaks of lymph when you come out of the shower transforming to yellow scabs. It is allergy yes, but caused by a chemical product. And then, the many normal looking spots around I believe are the consequence of the irritation in the first place. That was and still is my belief.
That's not acne and not any kind of chemical burn I've ever seen and I've seen a lot. Sound more like shingles to me and if your getting that kind of reaction you better get it tested to find out exactly what it is. That kind of rash is more likely viral or bacterial and what you call lymph should be tested.
