Ingredient callouts
- This product also contains Vitamin C (Ascorbic Acid) 3.80% - 5.80% It can be helpful in stimulating collagen production, neutralizing free radicals in skin and improving pigmentation marks. We recommend to use up this product quickly after opening: Ascorbic Acid degrades fast when it gets in contact with air and light. The moment the product turns orange, it is a sign that a significant share of the vitamin C in it is no longer effective.
- An effective concentration of Panthenol (pro-vitamin B5) - about 0.35% - 0.80%. Panthenol helps strengthen the skin barrier, improve hydration and reduce inflammation in skin.
- Humectants (panthenol 0.35% - 0.80%, sodium hyaluronate 0.45% - 1.10%, arginine 0.90% - 1.35% and glycerin 1.30% - 1.90%). These ingredients help attract water to the upper layer of the skin and improve the skin hydration.

Moisturizing
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:
arginine, 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: arginine, aloe barbadensis leaf extract.
The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: panthenol
