What the product description says
“HYDRA-PROTECT + Regenerating Night Cream Face Organic”
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: anhydroxylitol, 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: linoleic acid

Product summary

Based on the ingredient list, "Laboratoires de Biarritz - HYDRA-PROTECT + Regenerating Night Cream Face Organic" can work well for skin moisturization. To work well, any moisturizer needs to include a combination of water-binding and emollient ingredients. Laboratoires de Biarritz - HYDRA-PROTECT + Regenerating Night Cream Face Organic ticks this box. Anhydroxylitol, glycerin, sodium hyaluronate and xylitylglucoside 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). Emollients in this formulation (linoleic acid, linolenic acid, butyrospermum parkii butter, helianthus annuus seed oil and squalane) help to reduce the moisture loss from the skin.
