Whether the laser treatment will help to remove the darkness of vaginal area or not? i am really conscious about the skin colour of my vagina, labia majora etc. if not then what should i do to get rid of this darkness?

"red' lasers lasers have been used to depigment spots and patches and melasma with some claiming great success. effects on large hair-bearing areas in continuation has not been tried extensively and may cause complications, Darker hue of these areas is normal in most people and may even be attractive . If you still want the change find a dermatologist/ plastic surgeon to do that
