All Skin Lightening or Whitening aesthetic treatments basically aim at reducing the Melanin Pigment in your skin. The the amount of Melanin Pigment determines the colour of the skin. Skin lightening is the process of changing the complexion or shade of skin color and making it lighter. Skin lightening is also done to remove* various skin blemishes such as sun spots and age spots. Skin lightening products give the skin a uniform and even tone thus making it look more appealing.
