Doctor: You have complained of rash on face. Sorry, you mentioned that a picture was attached, but i did not find it attached. F ace rash could be due to many reasons other acne, like fungal rash, bacterial infections, allergic rashes, moles, etc. To be diagnosed perfectly you must be examined in person and might require a skin biopsy too. Consult a dermatologist for treatment and followup.
