Product Summary
Judging from the ingredient list, "Lierac - Hydragenist The Rehydrating Radiance Cream + Free Radiance Moisture Routine" works well for improving skin hydration To work well, any moisturizer needs to include a combination of water-binding and emollient ingredients. Lierac - Hydragenist The Rehydrating Radiance Cream + Free Radiance Moisture Routine ticks this box. Urea, biosaccharide gum-1, glycerin, sodium hyaluronate and trehalose in this product (humectants) attract water molecules to the upper layer of the skin (the water comes from the outside air or from the deeper layers of the skin if the air is dry). Butyrospermum parkii butter, helianthus annuus seed oil, squalane, c10-18 triglycerides and cetyl alcohol in this product help decrease the water evoporation from the skin, so that it stays hydrated for longer. These ingredients also soften the skin and take away the feeling of tightness and dryness.

What does the product description say?
Hydragenist The Rehydrating Radiance Cream + Free Radiance Moisture Routine
Source: 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:
biosaccharide gum-1, 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: butyrospermum parkii butter, helianthus annuus seed oil.
The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: urea
Naturally 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
A 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
Helps 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
An 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
One of the best moisturizing ingredients. Attracts water into the upper layer of the skin
An oil naturally present in skin. Works as an emollient to soften the skin and form a protective layer on its surface without a greasy feeling.

A polyhydroxy acid (PHA) that helps shed the dead cells from the skin surface revealing smoother skin. Is believed to be genter than AHAs. It helps attract water to the upper layer of the skin and can stimulate production of skin's own hyaluronic acid resulting in improved hydration levels.

It can help reduce fine lines and wrinkles and improve skin tone with long-term application. Can help neutralize free radicals
