What the product description says
“Intensely hydrating and moisturising, it plumps up your skin, reduces the appearance of wrinkles, redness and visibly improves the appearance of skin’s texture and elasticity.”

This product contains good ingredients to attract water to the upper layer of the skin. These ingredients are called "humectants": glycerin, glyceryl acrylate/acrylic acid copolymer.

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 - 3-o-ethyl ascorbic acid - could be helpful for preventing or repairing signs of aging in theory, but there is no evidence that it actually works.

This ingredient 3-o-ethyl ascorbic acid might be able to help neutralize free radicals in skin and help it fight off some of the sun damage.

3-o-ethyl ascorbic acidEffect: LowA vitamin C derivative that is more stable but less potent than pure form of vitamin C. Can help neutralize free radicals and help reduce hyperpigmentation, but the required concentration is likely to be much higher than for the pure form of vitamin C, limiting the ingredient's effectiveness in products~1.2–1.9%
