my son 15 was diagnosed with eczema. He was put on doxitab to control the pimples and was told to use Eucerin range to help with the eczema. The eczema became worse and he had weeping patches on his face. I the went back to dr when I was told to change to the Cetaphil Dermarestore range. I mixed about 1ml of Persivate cream with 30ml of the Cetaphil and applied it to his face every morning and evening for a week. Also using a 50spf during the day. His skin recovered beautifully and we continued with the cream without the Persivate for another week. His skin was really beautiful! Then he started getting the odd pimple and was then told he can now go over to the Cetaphil Dermacontrol range, which we did. After 2 days of using it his skin has gone back to looking and feeling like sandpaper and weeping patches!! Please advise!
