My brothers both have/had bad eczema. Luckily I avoided it.
I do have
keratosis pilaris, or "chicken skin", on my arms. It's not uncomfortable in anyway, and I forget I have it really, since it's on the outside of my arms, and I don't see it much unless I've got my arms stretched out in front of me with my palms down.
My only annoying skin condition is that I've recently started to develop dry skin on my face, mainly just below the corners of my mouth, a little bit on my cheeks, and sometimes at the top of my forehead. It can get itchy at times.
But it goes away pretty quickly with some moisturiser.
Unfortunately I forget to moisturise regularly, so my dry skin pops up again, then I moisturise and it goes away, and as a result I fall out of the habit of moisturising so it returns.
