Hello doctor, my face is at least two shades darker than my neck,and ears. I have consulted multiple dermatologists here in Delhi over a period of three years. I have tried on almost all kind of treatments like vitamin c serum(25%), retinol, kojic acid, arbutin , glycolic acid (10%), peel off masks and every other thing . I have also been a regular user of bb cream with spf 30 everyday twice. But my problem is not getting solved. I have consulted almost 8 dermatologists over a period of 3 years nothing helped. I had followed all regimen religiously. I want my face to look like my neck and ears complexion. Kindly help. Thank you.
