Question
How to Treat Hereditary Ichthyosis?
Answer
Hereditary ichthyosis cannot be cured permanently, with the goal of treatment being to alleviate symptoms, increase the moisture content of the stratum corneum, and promote normal keratinization. Oral treatments include taking large doses of vitamin A or retinoic acid, but long-term use may lead to symptoms of toxicity such as osteoporosis and hair loss. Topical treatments include using 10% urea cream, 0.1% retinoic acid cream, or 20% cod liver oil ointment, which can help alleviate dry skin, scaling, and cracking.
