Ichthyosis is a group of skin disorders characterized by dry, scaly skin. It occurs due to a genetic mutation that affects the skin's ability to shed dead cells properly. This condition can vary in severity, with some individuals experiencing mild dryness while others may have thick, cracked skin that can lead to discomfort or infections. There are several types of ichthyosis, including ichthyosis vulgaris and lamellar ichthyosis. Treatment often focuses on moisturizing the skin and using topical therapies to improve its appearance and function. While there is no cure, proper care can help manage symptoms and enhance quality of life.
