Hi! I've had dry skin from childhood. A few years ago it got worse, probably due to frequent handwashing (comes with working with food). I got emollient cream from the doctor, which keeps that clear most of the time, although it does flare up from time to time. Also have psoriasis on my scalp.
Very recently (within the last few months), my skin has gotten a lot worse. I've just discovered I've an underactive thyroid, and dry skin is a symptom (along with tiredness, sluggish, depression, weight gain, brain fog, etc). Not sure if this will be any help to anyone, but it might be.
