Ichthyosis is a clinical keratotic disorder skin disease related to heredity. Ichthyosis can't be cured without special treatment, but some treatment measures can be taken to alleviate the disease. For patients with mild ichthyosis, skin dryness and desquamation will only occur in winter, and generally only skin moisturizers, such as urea ointment, can be used to effectively alleviate it. But for patients with obvious ichthyosis vulgaris, the skin will be dry and peeling all the year round.
