What the product description says
“This Hyper-Intensive Conditioning Serum helps to soothe and strengthen skin barrier along with a moisturizing effect.”
Source: Yesstyle

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: algae extract, betaine.

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: algae extract, caprylyl glycol.

The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: madecassoside

MadecassosideHeroEffect: HighAn antioxidant that is typically derived from plant Centella Asiatica. It can help neutralize free radicals in skin and support skin barrier function. It could, however, itself be irritating. It is often unstable in formulations~0.55–1.25%
BetaineKey active· HumectantEffect: HighHelps attract water to the upper layer of the skin and improves the product texture~2.6–3.9%
Hydrolyzed hyaluronic acidKey active· HumectantEffect: HighOne of the best moisturizing ingredients. Attracts water into the upper layer of the skin. A version of it is naturally present in skin~1.3–1.9%
Algae extractKey active· Humectant, EmollientEffect: HighPlant extract that helps the skin to attract water and make it more smooth for touch. Also shows promise of anti-aging properties, but research is not extensive yet~1.1–1.7%
Biosaccharide gum-1Key active· HumectantEffect: HighHelps attract water to the upper layer of the skin and is claimed to provide a longer-lasting hydration because of its ability to create a water-binding film on the surface of the skin~0.35–0.8%
TrehaloseKey active· HumectantEffect: HighA sugar that attracts water to the upper layer of the skin~0.2–0.75%
Saccharide hydrolysateKey active· HumectantEffect: High~0.15–0.5%

Butylene glycol· HumectantEffect: LowUsed to create a nice product texture and help delivery of other ingredients. Might be somewhat helpful in attracting water to the upper layer of the skin~3.4–5.1%
Camellia sinensis leaf extractEffect: LowCan contain potent anti-oxidant compounds (abbreviated ECG, GCG, EGC, and EGCG) that might help protect the skin from free radicals. Can help calm down inflammation and has some anti-bacterial properties. Unfortunately, these antioxidants are unstable and lose their effectiveness very quickly in products. The concentration of the antioxidant compounds in the extract also tends to be low to be effective in topical formulation~0.45–1.05%
Caprylyl glycol· Humectant, EmollientEffect: LowHelps preserve products and creates a nice product texture~0.1–0.5%

Works well

This product contains antioxidants (madecassoside) that can help neutralize free radicals in skin. By doing so, they can lessen the damage the skin gets from the UV light (sun).

The following ingredients - camellia sinensis leaf extract also can have an antioxidant effect, but there is less evidence to confirm their effectiveness in skin.

May help

This product contains madecassoside. There is some human evidence that this ingredient helps reduce and prevent fine lines and wrinkles and improve skin elasticity and firmness, though it is smaller or less consistent than the evidence for the best anti-aging ingredients.
