Skin problems seem to be linked to mineral and vitamin deficiencies and some people seem to have very good results using dietary supplements. I can recommend a company called 'Neways', which is an organisation based in the USA, but supplying in Europe also, dedicated to finding effective solutions to the health problems resulting from mineral/vitamin deficient diets. I am NOT employed by them, but my whole family has benefitted from the products. It's worth checking out their website at least - you can email them on email@example.com. Not sure of the USA contact. Good luck. Your friend sounds like she has a miserable life.
