What is the best treatment for demodex mites ? is accutane a good opition ?

Without knowing more about your history or previous treatments or severity of the disease, be sure that you understand a few things. Demodex is commonly found on skin biopsy and is not a reason to take Accutane. Accutane is indicated for severe nodular acne refractory to alternative therapies. I would advise trying alternate therapies first and seeking a second opinion regarding your rosacea. PDL may give you some benefit and is a more commonly used modality for rosacea.
