Detailed answer

Psoriasis is a chronic skin condition characterized by inflammation and abnormal skin cell growth. While the exact cause of psoriasis is not fully understood, it is believed to be influenced by genetic, environmental, and immune system factors. Hormonal changes can affect the immune system and potentially trigger psoriasis in individuals with ichthyosis, a genetic skin disorder that causes dry and scaly skin. However, it is important to note that not all individuals with ichthyosis will develop psoriasis, as multiple factors contribute to the development of psoriasis. If you are concerned about the interaction between ichthyosis and hormonal changes, it is recommended to consult with a dermatologist for proper evaluation and management.
