Hi, I have been struggling with the same symptoms for 1,5 years now. It started just like yours and then it spread to my right eyelid. I was diagnosed with a seborrehic dermatitis and given steroids. The rash would go away while I used the steroids but the redness stayed. Anyway, I think I figured it out yesterday. I believe I am allergic to Methylisothiazolinone in my conditioner. Check all your products!!!! The victims even have a FB page. I can not attach the links so do your own research.
