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.
- Panthenol (pro-vitamin B5) at about 0.35% - 0.80% concentration. In this concentration, Panthenol works effectively to improve the skin barrier and reduce inflammation.
- 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
What does the product description say?
Hyaluronic Acid deeply hydrates and plumps the skin instantly hydrating, replenishing, and boosting the skin's ability to retain moisture, revealing a smoother youthful complexion.

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

Can contain potent anti-oxidant compounds (abbreviated ECG, GCG, EGC, and EGCG) that might help protect the skin from free radicals.

The concentration of the antioxidant compounds in the extract also tends to be low to be effective in topical formulation
Anti-oxidation
This product contains antioxidants (arbutin) that might be able to help neutralize free radicals in skin to lessen the damage it gets from the UV light (sun). There is not enough evidence to confirm their effectiveness in skin though.
Beta-arbutin. Can help to reduce hyperpigmentation and has an anti-oxidant effect when used in high enough concentration. Is less effective compared to alpha-arbutin
