Hello Patricia,
Welcome to our ichthyosis bulletin board. I also watched the show on the TLC channel called My Skin Is Killing Me.The name of the man from Chengjiang, China is Sun Cheng. Indirectly we have communicated with him, and expressed he is not alone in his experiences with ichthyosis. I would imagine the pill he was taking was a retinoid possibly Soriatane (Neotigason outside the U.S.) or possibly Accutane. Possibly our ichthyosis friends who take the retinoids could tell us exactly what pill Sun Cheng is using. Patricia, also check out our FIRST foundation website at:www.firstskinfoundation.org. Take care Patricia.
