What the product description says
“Superdose™ C Vitamin C Oxygen Boosting Moisturiser”
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: glycerin, hydrolyzed soy protein.

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, helianthus annuus seed oil.

Oleyl erucateKey active· EmollientEffect: HighHelps soften the upper layer of the skin and create a nice product texture~1.3–1.5%
Helianthus annuus seed oilKey active· Emollient, OcclusiveEffect: HighA great emollient due to its high linoleic acid content. One of the most effective plant oils in helping skin hydration and repairing skin barrier function~0.15–0.3%
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~2.4–3%
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~4.7–5.7%
Cetyl alcoholKey active· EmollientEffect: MediumA non-drying alcohol that works to soften the skin and stabilize product formulations helping oil and water mix together~0.9–1.1%
Hydrolyzed soy proteinKey active· HumectantEffect: MediumHelps attract water to the upper layer of the skin. Might have some anti-aging, anti-oxidant, and skin lightening properties, but solid evidence is missing~0.3–0.55%
Coco-caprylateKey active· EmollientEffect: MediumAn emollient that softens skin and creates a nice product texture~2–2.4%
Caprylyl glycol· Humectant, EmollientEffect: LowHelps preserve products and creates a nice product texture~0.5–0.75%
C15-19 alkaneEffect: LowHelps soften the upper layer of the skin and create a nice product texture~4.2–5.1%

Butyrospermum parkii butterUnder-dosedEffect: HighA great moisturising ingredient that softens the skin and reduces water loss from its upper layer. It also can be helpful in protecting skin from free radicals~0.55–0.8%
Persea gratissima oilUnder-dosedEffect: HighAn emollient that helps soften the skin and could be helpful in repairing its barrier function~0.45–0.7%
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~0.2–0.4%
Ascorbyl tetraisopalmitateEffect: Low, below effective doseA vitamin C derivative. Studies show that is might be effective in reducing hyperpigmentation, but there are no studies confirming that it is effectively converted into the bioavailable form of Vitamin C in skin. It is not clear how this derivative compares in effectiveness to the topical application of bioavailable form of vitamin C (L-ascorbic acid)~3.1–3.8%
