What the product description says
“High-performance, hydrating serum with hyaluronic acid and seaweed is clinically shown to improve elasticity and visibly reduce lines & wrinkles while boosting hydration.”

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

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.This ingredient - hyaluronic acid - could be helpful for preventing or repairing signs of aging in theory, but there is no evidence that it actually works.
