Gives you a bad rash

I bought some Prevage Serum years ago and really liked it. Last year I bought 50 ml and it seemed fine but I then one day got a bad rash on my neck and chest, it lasted a couple of weeks and ended up going to the doctors, she didn't know what it was but gave me some anti-histamine tablets and some cream. A few months later it happens again. I cut out everything to try and find out what it was. I stopped using Prevage then one night I put it on my face in the morning my face was red and blotchy. I got some anti-histamine tablets and used after sun cream, it lasted for four days and I couldn't go out in the sun. If you have fair skin you cannot use this cream.
