What the product description says
“What it is: A hydrating self-tanning serum to visibly boost your skin from the outside in.”
Source: Sephora

This product contains good ingredients to attract water to the upper layer of the skin. These ingredients are called "humectants": biosaccharide gum-1, saccharide isomerate.

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).

The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: panthenol

PanthenolHero· HumectantEffect: HighHelps attract water to the upper layer of the skin and can help improve skin barrier function~0.95–1.45%
TrehaloseKey active· HumectantEffect: HighA sugar that attracts water to the upper layer of the skin~2.1–3.2%
Saccharide isomerateKey active· HumectantEffect: HighHelps attract water to the upper layer of the skin~1.2–1.8%
Sodium hyaluronateKey active· HumectantEffect: HighOne of the best moisturizing ingredients. Attracts water into the upper layer of the skin~0.15–0.7%
Biosaccharide gum-1Key active· HumectantEffect: HighHelps attract water to the upper layer of the skin and is claimed to provide a longer-lasting hydration because of its ability to create a water-binding film on the surface of the skin~0.15–0.7%

NiacinamideUnder-dosedIs proven to be effective in reducing blemishes, evening out skin tone and helping to improve lines and wrinkles.

This product does not contain ingredients that are able to reduce fine lines and wrinkles or help with skin elasticity, but it can improve the look of the skin temporarily through moisturization. Well-moisturized skin might also be able to repair the sun damage better.
