I have dark waistline and butt. My face and chest is extremely fair. I want my waistline also to be like my face. Soft and fair. How can I cure dark waistline?

Hmm... nice one.
Its just to concentrate on that area and give it more attention. Many people forget to rub those parts.
I also think its because the skin on those areas are kind of thick... so it takes time for the absorption.Exfoliating that area is another must to.
