The primary treatment approach for ichthyosis is focused on moisturization and hydration of the skin. Ichthyosis is characterized by dry, scaly skin resulting from a defect in the skin's ability to shed and replace dead skin cells properly. The lack of hydration exacerbates the condition, leading to increased scaling and dryness.

Moisturizers play a crucial role in managing ichthyosis by forming a barrier that helps to retain moisture in the skin. Products containing ingredients such as urea, lactic acid, and glycerin can improve skin texture and hydration levels. Regular application of emollients is essential to maintain skin integrity and comfort for individuals with this condition.

Other treatment options, while they can be relevant for specific symptoms or complications of ichthyosis, such as inflammation or secondary infections, do not address the core issue of skin dryness and scaling as effectively as moisturization and hydration. Therefore, the consistent use of moisturizing agents is considered the cornerstone of ichthyosis management.
