No.
There is no evidence that rubbing glutathione into your skin will be absorbed into your cells. The molecule itself is quite large and entry into the cells is difficult at best.
And even if the glutathione were to make it into your skin cells, it still would not have the desired effect, because glutathione does not lighten your skin, nor does taking the building blocks for glutathione lighten your skin.
