Keratinization disorders are conditions that affect the process of keratinization, where skin cells produce keratin, a protein that helps protect the skin. These disorders can lead to abnormal skin growth, thickening, or scaling, often resulting in dry, rough patches. Common examples include psoriasis and ichthyosis, which can vary in severity and appearance. These disorders can be caused by genetic factors, environmental influences, or underlying health issues. Treatment options may include topical therapies, moisturizers, and sometimes systemic medications to help manage symptoms and improve skin appearance. Regular dermatological care is essential for effective management.
