Not all dry skin works the same way.
Everyday dryness — cold air, frequent washing — affects skin whose moisture system still works, and it tends to recover once protected. Diabetic dry skin can run on a different mechanism. Nerve changes can interrupt the signal that tells the foot's glands to produce moisture, so the dryness comes from inside rather than from the environment.
It's one reason diabetic skin can stay dry despite regular care — and worth raising with a foot care professional.
