Ichthyosis is a dominant genetic disease. If possible, you can take a hot spring bath and apply health care oil to soften the skin, reduce scales and itching, and prevent the skin from being too dry.
Suggestion:
The disease does not affect health, and it is not treated lightly; In severe cases, vitamin A can be taken, and 10% cod liver oil ointment or 10% salt ointment can be applied locally.
