My 16 yr old son has dry scaley skin patches on eyelids....itchy eyes, and nasal stuffiness also. We have been using a vaporizer to help the stuffiness, but since right after starting he developed itchy eyes and now the scaley dry skin on his eyelids. Could this have something to do with the vaporizer? I only use water and a small pinch of salt in the vaporizer, no vicks or nothing like that.
