hi. i'm indian, male. i was born with a pale yellowish golden skin colour. but now it has turned brown and dark brown in private areas and nape of the neck and like. probably because i haven't washed properly over years. will i be able to restore my skin colour to the colour i was born with? what medicines can i use. also will i be able make it peachy? because my skin colour on plam is light pink. thank you for reply.
