Why the effect of your treatments are so short-lived?

 Why the effect of your treatments are so short-lived? Because many treatments only remove scales temporarily, but ichthyosis patients have problems with skin function, and the skin cell growth cycle is short. As long as the skin function is not resolved, the scales will continue to regenerate.

It's like a house with a broken roof that keeps leaking water to the floor, just constantly sweeping the water off the floor is useless, water will keep leaking in unless the broken roof is repaired.
