What the product description says
“The addition of Pyruvic Acid enhances the effects of VCIP, for plumper skin with a radiant complexion and even skin tone.”
Source: Face the future

This product can help reduce hypepigmentation and even out the skin tone because it contains the following effective ingredients: glutathione

Keep in mind that you would need to apply any topical skincare targetted at hypigmentation consistently for a couple of months to get a result. No topical skincare product can help get rid of hyperpigmentation (including post-acne marks and age spots) instantly.

GlutathioneKey activeEffect: HighA peptide that can help neutralize free radicals in skin and reduce melanin production resulting in skin lightening effect and reduction in hyperpigmentation. It can also help attract moisture to the upper layer of the skin~0.01–0.05%
Ascorbyl tetraisopalmitateUnder-dosedA vitamin C derivative. Studies show that is might be effective in reducing hyperpigmentation, but there are no studies confirming that it is effectively converted into the bioavailable form of Vitamin C in skin. It is not clear how this derivative compares in effectiveness to the topical application of bioavailable form of vitamin C (L-ascorbic acid)~4.6–6.8%

This product contains threonine. This ingredient might be able to help reduce and prevent fine lines and wrinkles, improve skin elasticity and firmness, but there is not enough evidence that it actually works.

This product contains antioxidants (glutathione, thioctic acid) that can help neutralize free radicals in skin. By doing so, they can lessen the damage the skin gets from the UV light (sun).

Side benefit · Glycerin, Lysine hcl + 10 more
Works

This product contains good ingredients to attract water to the upper layer of the skin. These ingredients are called "humectants": glycerin, glycine.

When humectants are on the surface of the skin, they “pull in” the moisture from the outside environment, or from within deeper layers of the skin. If the air is dry, humectants can speed up the moisture loss from the skin. This is why it is a good idea to use another product on top of this one to help "seal in" the moisture (look for ingredients like dimethicone, squalane, oils and butters).
