Can over the counter glutathione whiten your skin?

One View:

L-glutathione pills need vitamin C to whiten skin, but results will show after a few months yet.

Another View:

Oral glutathione or L-glutathione is destroyed in your gut, and there is no medical evidence to suggest that this will whiten your skin.

Raising your glutathione with the building blocks for glutathione, for intracellular glutathione production, however, serves to protect your skin cells from sun damage as an antioxidant. In this way, it may help you to retain your fair complexion if you have one already.

I am in the sun quite a bit, my glutathione levels are high, and the color of my skin rarely darkens.
