Moisturizing
What does the product description say?
Glycerine and biosaccharides Gum-1 provide pleasant moisture.
Source: German Drugstore
This product contains good ingredients to attract water to the upper layer of the skin. These ingredients are called "humectants": betaine, biosaccharide gum-1.
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

Anti-oxidation
This product contains antioxidants (3-o-ethyl ascorbic acid) that might be able to help neutralize free radicals in skin to lessen the damage it gets from the UV light (sun). There is not enough evidence to confirm their effectiveness in skin though.
A 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

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
Anti-aging
What does the product description say?
The vitamin C serum derivative can stimulate the skin's own collagen production and protects against oxidative skin damage caused by environmental factors.
Source: German Drugstore
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.
