My mom skin is very dry and itches and blisters appear if she gets exposed to sun. This started after her menopause. It is even on her scalp and her hair keeps falling. Doctors have suggested to stay out of sunlight and use suncote sunscreen gel and momate cream. Staying indoors away from sunlight is impossible always. And sunscreen and the ointment doesnt help. She has fair complexion. Apart from sun, there is no reaction with any kind of food she eats. If she is indoors, she is better.
