My husband has used this product twice now with no problems. On this third occasion he's had massive chemical burns to the beard area that is now travelling up his face and also burning to his ears. He is in so much pain and is so worried that this will cause permanent scars to his face. We will be calling the doctor in the morning. I've given him anti-histamines and paracetamol but it just seems to be getting worse. I may have to take him to the hospital over night.
