What the product description says
“This cream delivers intense moisture to skin and targets visible signs of aging.”
Source: Yesstyle

This product contains serine. 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.

SerineKey activeEffect: MediumAn amino-acid that helps to attract water to the upper layer of the skin. In combination with other amino-acids, might help to reduce fine lines and wrinkles~0.25–0.45%
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~0.3–0.6%
SericinEffect: Low~0.25–0.45%
TocopherolEffect: Low, below effective dosePure form of vitamin E. Can help moisturise and protect the skin from free radicals. Often used to help stabilise other ingredients or the formula itself~0.2–0.35%

What the product description says
“This cream delivers intense moisture to skin and targets visible signs of aging.”
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: alanine, glycerin.

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, squalane.

DimethiconeKey active· Emollient, OcclusiveEffect: HighA silicone that helps to reduce water loss from the surface of the skin. Can temporarily "fill in" lines and wrinkles, absorb oil, and create a nice product finish~2.4–2.9%

This product contains antioxidants (camellia sinensis leaf extract) that can help neutralize free radicals in skin to lessen the damage it gets from the UV light (sun). There is some human evidence for this effect in skin, though it is smaller or less consistent than the evidence for the best antioxidants.
