Has anyone tried adult acnomel spot treatment? It contains sulfur, and resorcinol. I used this product twice, years apart, on two different occasions, and got terrible blister type lesions where the medicine was. I went on the dr. And was diagnosed with a sulfur/ sulfa allergy. I've had acne for 13 years. Typically located on the lower half of my face. Is there any connection between long term acne, and eating sulfur foods? I would assume if I cannot put it on my face, ingesting it would be an issue, and is maybe contributing to my acne. Any one else out there with a similar issue? Thank you!
