What the product description says
“Hydrating Serum”
From product name

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

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: urea

UreaHero· HumectantEffect: HighNaturally present in skin (urea makes up about 7% of natural moisturizing factors in skin). Attracts water to the upper layer of the skin. Also has a positive effect on the skin barrier beyond the humectant action. Can enhance penetration of other ingredients. Is an exfoliating ingredient when used in high concentrations~0.3–0.75%
GlycerinKey active· HumectantEffect: HighOne of the best moisturizing ingredients. Naturally present in skin. It attracts water to the upper layer of the skin working as a humectant~0.55–1.25%
Sodium pcaKey active· HumectantEffect: HighNaturally present in skin and helps to attract water to its upper layer~0.35–0.8%
TrehaloseKey active· HumectantEffect: HighA sugar that attracts water to the upper layer of the skin~0.2–0.75%
Sodium hyaluronateKey active· HumectantEffect: HighOne of the best moisturizing ingredients. Attracts water into the upper layer of the skin~0.15–0.65%
Butylene glycol· HumectantEffect: LowUsed to create a nice product texture and help delivery of other ingredients. Might be somewhat helpful in attracting water to the upper layer of the skin~1.6–2.4%
Polyquaternium-51Effect: LowAn emollient that helps create a nice silky finish on the skin~0.35–0.8%
Sorbitol· HumectantEffect: LowHelps attract water to the upper layer of the skin and improves the product texture~0.3–0.7%
Caprylyl glycol· Humectant, EmollientEffect: LowHelps preserve products and creates a nice product texture~0.2–0.8%
Glyceryl caprylate· EmollientEffect: LowAn emollient that can also help water and oil mix together, as well as prevent bacteria growth in products~0.15–0.6%
LecithinEffect: Low, below effective doseUsed mostly for creating emulsions - helping oil and water mix together. Helps soften the upper layer of the skin~0.3–0.7%
Cucumis sativus fruit extractEffect: Low, below effective doseMight be somewhat helpful in reducing hyperpigmentation and neutralizing free radicals but its typical concentration in a product is too low for having an effect~0.1–0.35%
Laminaria digitata extractUnder-dosedSeaweed extract that helps the skin to attract water and make it more smooth for touch. Also shows promise of anti-aging properties, but good research is lacking at the moment~0.15–0.65%

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.
