What the product description says
“This moisturizing gel is formulated with oligo-elements and vitamins.”
Source: Sephora

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, aspartic acid.

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: butyrospermum parkii butter, dimethicone.

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

PanthenolHero· HumectantEffect: HighHelps attract water to the upper layer of the skin and can help improve skin barrier function~0.65–0.95%
UreaHero· HumectantEffect: HighNaturally present in skin (urea makes up about 7% of natural moisturizing factors in skin). Attracts water to the upper layer of the skin. Also has a positive effect on the skin barrier beyond the humectant action. Can enhance penetration of other ingredients. Is an exfoliating ingredient when used in high concentrations~0.2–0.35%
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~5.6–6.9%
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~3.1–3.8%
Butyrospermum parkii butterKey active· Emollient, OcclusiveEffect: 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~2.1–2.5%
Prunus armeniaca kernel oilKey active· EmollientEffect: HighAn emollient that helps soften the skin~1.5–1.8%
CholesterolKey active· EmollientEffect: HighAn emollient that is naturally found in skin~0.45–0.65%
2-oleamido-1,3-octadecanediolKey activeEffect: HighHelps soften the upper layer of the skin and slow down the water loss over time~0.4–0.6%
FructoseKey active· HumectantEffect: HighHelps attract water to the upper layer of the skin~0.35–0.6%
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~0.3–0.55%
GlucoseKey active· HumectantEffect: MediumHelps attract water to the upper layer of the skin. Could be helpful in restoring the skin barrier function~0.3–0.6%
Manganese gluconateKey activeEffect: HighMight be able to help restore skin barrier function supporting its hydration~0.15–0.3%
Aspartic acidKey active· HumectantEffect: HighAn amino-acid that helps increase skin hydration and might help to slightly improve skin firmness, potentially reducing lines and wrinkles~0.15–0.25%
SucroseKey active· HumectantEffect: HighCan help attract water to the upper layer of the skin. In crystal form, it can work as a gentle exfoliant, gentler than the salt scrub. Helps stabilize the emulsion~0.15–0.25%
Glutamic acidKey active· HumectantEffect: HighAn amino-acid that helps attract water to the upper layer of the skin~0.15–0.3%
AlanineKey active· HumectantEffect: HighAn amino-acid that helps to attract water to the upper layer of the skin and might help to lighten the skin, but solid evidence is lacking~0.1–0.2%
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~2.4–2.9%
Magnesium gluconateEffect: LowA mineral that might be able to support skin hydration, but convincing research on its effectiveness in topical skincare is lacking~0.45–0.65%
Dextrin· HumectantEffect: LowA sugar that is used to stabilize the product formulation. Can help attract water to the upper layer of the skin~0.2–0.35%
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~0.25–0.5%
Copper gluconateUnder-dosedTypically used to stabilize the product formulations. It is a salt of polyhydroxy acid (PHA) and in larger concentrations, can help shed the dead cells from the skin surface revealing smoother skin. It can help attract water to the upper layer of the skin. Might to be helpful against acne and clogged pores. Could be helpful in neutralizing free radicals, but solid research is missing~0.2–0.35%
Zinc gluconateUnder-dosedTypically used to stabilize the product formulations. It is a salt of a polyhydroxy acid (PHA) and in larger concentrations, can help shed the dead cells from the skin surface revealing smoother skin. It can help attract water to the upper layer of the skin. Might to be helpful against acne and clogged pores. Could be helpful in neutralizing free radicals, but solid research is missing. Due to the zinc content, might help calm down inflammation in skin~0.15–0.3%

This product contains aspartic acid. This ingredient might be able to help reduce and prevent fine lines and wrinkles, improve skin elasticity and firmness, but there is not enough evidence that it actually works.

Ascorbyl glucosideUnder-dosedA vitamin C derivative that is more stable but less potent than pure form of vitamin C. Has a potential to boost collagen production, nutralise free radicals and reduce hyperpigmentation, but the required concentration is likely to be much higher than for the pure form of vitamin C, limiting the ingredient's effectiveness in products~0.25–0.45%
