Is There Any Difference Between Toning And Bleaching The Skin?

undefinedI have heard people argued a lot about skin toning and skin bleaching and to my surprise people confuse skin toning and beaching from skin toning with bleaching creams. I checked to find the differences between the two: tone skin and bleach skin.
 Toning
In cosmetics, skin toner or simply toner refers to a lotion or wash designed to cleanse the skin and shrink the appearance of pores, usually used on the face.

Skin bleaching
Skin whitening, skin lightening, and skin bleaching refer to the practice of using chemical substances in an attempt to lighten skin tone or provide an even skin complexion by lessening the concentration of melanin.

But it still gets me confuse when I see a person who use to be very black, all of a sudden their color changes to light brown, do you say they toned their skin or bleached?...
