Introduction
Ichthyosis is a group of skin disorders that cause the skin to become dry, rough, thick, and scaly, giving it a fish-scale-like appearance. The condition may be inherited (genetic) or acquired later in life. Although there is no permanent cure for inherited ichthyosis, proper skin care and treatment can significantly improve symptoms and quality of life.
ICHTHYOSIS
What is Ichthyosis?
Ichthyosis is a disorder in which the skin does not shed dead cells normally. As a result, dead skin builds up, forming thick scales. The severity varies from mild dryness to severe scaling over large areas of the body.
