I'm also on thyroid meds -- so maybe it's related to hypothyroid. On the other hand, perhaps it's just genetic and not diet related at all. I know that psoriasis and acne can be alleviated with a paleo type diet -- but perhaps other skin conditions are just not. It's so frusterating in the summer when one shows more skin. My husband who eats a horrid diet and is a decade older than me has silky smooth skin and doesn't use any lotion ever. I should have picked a husband at least 2 decades older -- if my skin continues aging in "dog years", people will start asking if he's my son soon...
