What does the product description say? "This formula also assists in reducing the appearance of cellulite and uneven skin tone."
WIMJ summary
This product contains ingredients (pinus pinaster bark extract) that could help reduce hyperpigmentation (for example, post-acne marks or age spots) in theory, but there is not enough evidence that they actually work.

WIMJ summary
This product contains good ingredients to attract water to the upper layer of the skin. These ingredients are called "humectants": glycerin, propylene glycol.
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).
