“Dayscreen Moisturizer SPF 30”
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.

within deeper layers of the skin. The following ingredients in this product do the job:
sodium hyaluronate.
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 are especially good for supporting the skin barrier and helping with the hydration level: ceramide np
