What the product description says
“Vitamin c face cream”
From product name

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: arginine, 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: arginine, dimethicone.

CyclopentasiloxaneKey active· EmollientEffect: MediumA silicone that helps improve the product texture and spreadability. Can absorb oil creating a short-term mattifying effect on the skin~4–4.9%
GlycerinKey active· HumectantEffect: HighOne of the best moisturizing ingredients. Naturally present in skin. It attracts water to the upper layer of the skin working as a humectant~3–3.7%
Cetearyl alcoholKey active· EmollientEffect: MediumA non-drying alcohol. Works as an emollient. Helps water and oil mix together and creates a nice product texture~2.3–2.8%
ArginineKey active· Humectant, OcclusiveEffect: HighAn amino acid that is naturally present in skin and helps keep it hydrated. When used together with AHAs, it can reduce their irritating effect on the skin~0.7–1.05%
Cocos nucifera fruit extractKey active· EmollientEffect: HighAn emollient. Found to be as effective as a moisturizer for dry skin as mineral oil. Could be comedogenic~0.5–0.7%
Persea gratissima fruit extractKey active· EmollientEffect: High~0.5–0.75%
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~0.25–0.5%
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~5.6–6.9%
Glyceryl stearate· EmollientEffect: LowAn emollient that softens the skin and forms a protective layer on its surface. Helps water and oil mix together~0.25–0.5%
Oleic acid· EmollientEffect: LowHelps soften the upper layer of the skin. At the same time, it can weaken the skin's barrier enhancing penetration of other ingredients and increasing the risk of skin dryness~0.2–0.35%
Stearic acidEffect: Low, below effective doseHelps oil and water mix together and works as an emollient~0.35–0.6%
Persea gratissima oilUnder-dosedAn emollient that helps soften the skin and could be helpful in repairing its barrier function~0.35–0.6%
Simmondsia chinensis seed oilUnder-dosedSoftens the upper layer of skin and helps restore the healthy skin barrier. Has shown to help calm down inflammation in skin. It is a stable oil, meaning that it retains its properties even when exposed to air.~0.3–0.6%
