What the product description says
“Excellent for all skin types and for all ages, this powerful botanical serum leaves the skin moist and smooth.”
Source: Bluemercury

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

What the product description says
“Reduces the appearance of fine lines & wrinkles”
Source: Face the future

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 arbutin might be able to help neutralize free radicals in skin and help it fight off some of the sun damage.
