Judging from the ingredient list, "OSKIA - Rest Day Comfort Cream" works well for improving skin hydration The formulation is based on a combination of good humectants and emollients. Both are needed to increase the skin hydration level. Panthenol, alanine, arginine, betaine and glutamic acid 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). Oenothera biennis oil, arginine, butyrospermum parkii butter, chondrus crispus extract and cocos nucifera oil 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.

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, arginine.
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: arginine, butyrospermum parkii butter.
The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: panthenol
