My sister got black rashes on below eye, chick and in some other area on face without itching or paining...now are the proper treatment that we can...?

Need to be examined: These types of questions are difficult to answer as the rashes need to be examined to know the cause of the rash to answer what treatment needs to be done. Please see an ophthalmologist or a dermatologist for exam and treatment.

Eval: This can't be diagnosed with the information that is available. A history, physical examination & other studies may be needed to determine cause/causes. Once accurately assessed a treatment plan can be developed.
