What the product description says
“Glycolic Acid 20% Resurfacing Peel for Discoloration”
From product name

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~0.4–0.9%

This product contains palmitoyl tripeptide-28. 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 good ingredients to attract water to the upper layer of the skin. These ingredients are called "humectants": copper pca, glycerin.

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).

Exfoliation
No ingredient credited for this claim
Not delivered
What the product description says
“Glycolic Acid 20% Resurfacing Peel for Discoloration”
From product name

This product does not contain effective exfoliating ingredients. It might be able to deliver physical exfoliation, that is scrub off some of the dead cells on the surface of the skin. We do not recommend physical exfoliation, because it is not uniform (some bits of skin can get exfoliated too much while others not at all). It can also traumatize the skin and aggrevate acne and other skin conditions.

Anti-oxidation
