I have luckily never really had spots on my face, even as a teenager but I am in my late thirties and still have a horribly spotty back. I have tried changing shower gels with no effect. It's been like this for over 20 years so I don't think there are any other irritants or anything. I have a dress with a sheer back that I want to wear next weekend and have realised that the three enormous spots at the top of my back are all visible through through the dress- is there anything I can do?
