Hi doc,thanks for all the advice you've been giving,it's helped me a lot. My problem now is that when I was younger I had naively used bleaching creams containing hydroquinone. Now I'm fair but my knuckles are copiously dark. Could you please recommend an oil or something that I can used to lighten just my knuckles,thanks!
