What causes blotchy skin on your upper arm?

Answer by  loribugher (462)

It can be related to dry skin, or keratosis pilaris. If there are bumps related to it, it's probably KP. If merely dry skin, try using Lubriderm.

Blotchy skin can be causd by acne, or simply skin that is just irritated. Usually it is nothing to worry about.

A well-known cause is sun damage. If the skin appears to be a purple color, you should see a dermatologist and he might prescribe cream to bleach it.
