I think I have to add another issue in my multiple skin issues list. It is eczema. I've been getting this stinging dryness around my mouth for over two years now and initially I was suspecting an allergy to lipstick or that it was related to perioral dermatitis or most recently seborrheic dermatitis but even after treating all those conditions it's still continuing. I'm not positive as I have so many issues and they could all be connected but I'm thinking it may be eczema and maybe related to an allergy..the same allergy that's causing the hives. It tends to heal then I notice new small patches of dry skin and this cycle has caused hyper pigmentation around the corners of my mouth. It could potentially be Seb derm as I was suspecting but I'm leaning more towards eczema.
