I have had a rash & pimples on my face since I was a teenager, I am now 34 and am from Africa. I have been using a product called Bio Claire which worked very well the past 10 years but I stopped using it about a month ago because of concerns over an ingredient called BHT in it. I now have an itchy face, with rash around my chin area and over my cheeks and forehead. Sometimes there are small light-coloured patches on my face. My nose and the area around it is free of all blemishes, though it is rather oily. Can you help? I don’t know what to use to cleanse my face or moisturise it or to get rid of the rash.
