Complexion refers to the natural color, texture, and appearance of the skin, especially that of the face.
The variation in complexion has also been used through the centuries to justify racism, the color of one's skin believed to be proof of one people’s innate inferiority or superiority over another.
A person’s complexion is, however, a biological trait.
And also my complexion is brownish on my face and the back of hands, but my rest of the body is nearly fair, so i want to become fair colored.
You won't be able to have a complete fair complexion, although you may be able to lighten your skin by a few shades.
If your complexion is flawless, your skin can look beautiful, dark or light, and while there isnt much you can do to change your skin colour, your complexion is definitely under your control.
