What the product description says
“Essential amino acids work to reduce fine lines and other signs of ageing, while oil-absorbing spheres help ensure a shine-free result.”
Source: SpaceNK

This product can help reduce and prevent fine lines and wrinkles, improve skin elasticity and firmness because it contains adenosine.

Keep in mind that it typically takes at least 6 weeks to notice any results because the changes that are needed to improve fine lines and elasticity happen in the deeper layers of the skin. No topical anti-aging product can “erase” wrinkles or fully reverse signs of aging.

AdenosineKey activeEffect: HighMight help improve cell turnover and reduce inflammation in skin. One study shows that the ingredients might be able to help reduce dynamic wrinkles (for example, in the corners of the eyes or on the forehead)~0.01–0.05%
Dipalmitoyl hydroxyprolineEffect: LowIs claimed to stimulate collagen and elastin production, as well as work as an anti-oxidant. There is however not enough evidence for its effectiveness~0.9–1.4%

What the product description says
“Oil Free Moisturiser”
Source: Kate Somerville

This product can help improve hydration of the skin with the two types of ingredients.

The first type is called “humectants”:
these ingredients help attract water. 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. The following ingredients in this product do the job: ahnfeltiopsis concinna extract, algae extract.

This product also contains ingredients called “occlusives”. They help reduce the speed with which our skin loses moisture to the outside environment. These ingredients also help soften the upper layer of the skin, so it feels less tight and nicer to the touch. The following ingredients in this product do the job: dimethicone, pentaerythrityl tetracaprylate/tetracaprate.
