I am taking medications since last 3-4 years from famous dermatologists both online and offline but the results are zero. No medications seem to work on my face. It still is very very dark as compared to body colour. I always apply sunscreen whenever I go outside, always try to keep away from sun exposure, even tried different peelings like chemical peeling, carbon peeling, microdermabrasion etc as suggested by the dermatologists but always disappointed with the results. I wonder if any medication available which will work on my face. Please suggest what should I do.
