The 'unfair' beauty concept

Beauty includes innocence, youth looks, beautifull hairs and attractive eyes. Fair complexion is part of beauty. However it depends upon proper and artistic shape of the face, nose, eyes and its colour, colour of hairs, etc. Many dark skin girls are more beautifull than fair girls.
On the other hand, total black, ugly look, unclear skin and unhealthy hairs are not part of beauty.

I have seen many women even men also use many fairness cream to get fair skin.Does it work?

Complexion has nothing to do with the concept of beauty. Then how one perceives it, is a choice of an individual!

I don't think fairness creams can bring you more colour. For some days, it may work, but not for prolonged period. Keep your skin clean. It will automatically keep you more fresh and beautiful
