Ichthyosis is a group of skin disorders characterized by dry, scaly skin. This condition occurs due to a problem with the skin's ability to shed dead cells, leading to a buildup of scales. It can vary in severity and may affect different parts of the body. There are several types of ichthyosis, including ichthyosis vulgaris and lamellar ichthyosis. While some forms are inherited, others can develop due to environmental factors or other medical conditions. Treatment often focuses on moisturizing the skin and managing symptoms to improve quality of life.
