What the product description says
“Instant, long-lasting hydration thanks to Urea ISDIN 10%, which retains water and restores optimal hydration levels.”
Source: N/A

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: allantoin, sorbitol.

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, isopropyl myristate.

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

AllantoinKey activeEffect: HighHelps calm down inflammation in skin and can help reduce itching. Helps to repair the skin barrier and keep skin hydrated~0.55–0.85%
DimethiconeKey activeEffect: 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~1.4–1.7%
Isopropyl myristateKey activeEffect: HighAn emollient that helps soften the skin. Could be comedogenic~4.4–5.4%
Paraffinum liquidumHeroEffect: HighMineral oil. One of the most effective and well studied occlusive and emollient moisturizing ingredients. Helps reduce moisture loss in skin and repair skin barrier function~3.3–4%
Persea gratissima oilKey activeEffect: HighAn emollient that helps soften the skin and could be helpful in repairing its barrier function~0.75–1.1%
UreaHeroEffect: 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~9.3–11.4%
Cetyl alcoholKey activeEffect: MediumA non-drying alcohol that works to soften the skin and stabilize product formulations helping oil and water mix together~1–1.3%
Palmitic acidEffect: LowAn emollient that is naturally present in skin and helps soften it~0.6–0.9%
Cetearyl ethylhexanoateEffect: LowAn emollient that helps soften the skin~1.5–1.9%
SorbitolEffect: LowHelps attract water to the upper layer of the skin and improves the product texture~1.6–1.9%
Glyceryl stearateEffect: LowAn emollient that softens the skin and forms a protective layer on its surface. Helps water and oil mix together~2.4–2.9%
Lactic acidUnder-dosedEffect: HighAn exfoliating and moisturizing alpha-hydroxy acid (AHA). Typically causes less irritation than other AHAs, for example, glycolic acid. At high concentrations (about 15%), lactic acid can help reduce lines and wrinkles. Recent studies show that lactic acid can support the "good" bacteria living on skin's surface (healthy skin microbiome)~0.35–0.6%
Stearic acidEffect: Low, below effective doseHelps oil and water mix together and works as an emollient~0.7–1%
