About a year and a half ago I got really bad contact dermatitis on my face where it was bright red. It happened when I was cleaning and stupidly mixed products. I'm guessing whatever chemicals were in the products didn't react well. I also had stomach problems and diarrhoea for a few weeks afterwards. Possibly an allergic reaction to whatever was in the products? The redness would not go away and eventually I was given various steroid creams from my doctor to get rid of it.
I had no problems until a month ago when I was clearing out my wardrobe and the exact same thing happened, only on a lesser scale (dermatitis/stomach issues). I've since cleaned my wardrobe thoroughly (which made the redness worse) and thrown out loads of clothes but the redness keeps occurring. I'm convinced there's something lurking in my wardrobe, which I have an allergy to. Bacteria/dust/clothing/whatever. It's completely foxing me.
As for the redness, I'm trying to avoid using steroid creams because of the side effects. I'm applying savlon and aloe vera to my face but it's so persistant and stubborn. It took about 4 months to get rid of last time, and that was only after using steroid creams.
