I am asking this question for my 4 month old son. Small rashes all over his body. So we consult a skin specialist and she prescribed a cream permite (permethrin cream) and said to use two times that once in a week only but no changes in his rashes. Also used HHFUDIC (Mometasone furoate and fusidic acid) and dermadew cream. What are the main possibilities to came these type of rashes? What we do next?
