What the product description says
“This lactic acid serum removes dead skin for a smoother, more even skin tone.”
Source: Typology US

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

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.

Lactic acidKey activeEffect: HighAn exfoliating and moisturizing alpha-hydroxy acid (AHA). Typically causes less irritation than other AHAs, for example, glycolic acid. At high concentrations (about 15%), lactic acid can help reduce lines and wrinkles. Recent studies show that lactic acid can support the "good" bacteria living on skin's surface (healthy skin microbiome)~3.7–5.6%
Exfoliation
Lactic acid
Works well
What the product description says
“Highly concentrated in lactic acid, this serum gently exfoliates skin for a more even, radiant complexion.”
Source: Typology US

This product can help exfoliate the skin. In other words, it helps break down the bonds between dead cells on the surface of the skin and speed up the skin turnover. Skin often appears softer and brighter after exfoliation, but overdoing it can result in disrupted skin barrier. The following ingredient is doing the exfoliating job in this product: lactic acid.

Moisturizing
Not advertised by the brand · Diglycerin, Lactic acid
Works

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

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).
