May I to treat endocrine dyscrasia?

Endocrine dyscrasia will bring more skin questions, smallpox pustule, freckle and so on. I have doubt that my freckle is due to endocrine dyscrasia. Now some people introduce me to use this Ultrasonic Beauty Appliance. And I need to see the doctor or use this Ultrasonic Beauty Appliance first?
