Is there any way my wife can increase the beauty of her vag***?

My wife is 36 years old. We have a kid. How does she improve the way her vag*** looks? Color of the skin next to vag*** is black Even though she has fair complexion. When she wide opens her both the legs when she is ready for the play vag*** and part of the thighs and buttocks look black. Can she improve the looks of these parts by going to beauty parlour? We live in India. Can she change the colour by applying skin creams?
