How to treat hereditary ichthyosis

Patient's question:

Hereditary ichthyosis, the whole body is like a fish scale wrapped in heredity

Doctor's answer:

Hello, ichthyosis cannot be cured at present. The treatment goal is to relieve symptoms, increase the water content of the stratum corneum, and promote normal keratinization.
Suggestions:
- Oral administration: Take high-dose vitamin A, 100,000 to 300,000 IU per day, or vitamin A acid, 1 mg/kg per day. However, long-term use may lead to calcium loss in bones, hair loss, and other toxic symptoms.
- Topical treatment: Apply 10% urea cream, 0.1% vitamin A acid ointment, or 20% cod liver oil ointment, etc., which can help alleviate skin dryness, scaling, and cracking.
