What does the product description say?

Hyaluronic Serum

Source: 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: 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, pentylene glycol.

threonine 0.1% - 0.3%

Irritation risk:

Concentration: Effectiveness: HIGH

An amino-acid that helps to attract water to the upper layer of the skin. In combination with other amino-acids, might help to reduce fine lines and wrinkles

arginine 0.2% - 0.75%

Irritation risk:

Concentration: Effectiveness: HIGH

An amino acid that is naturally present in skin and helps keep it hydrated. When used together with AHAs, it can reduce their irritating effect on the skin

aspartic acid 0.15% - 0.6%

Irritation risk:

Concentration: Effectiveness: HIGH

An amino-acid that helps increase skin hydration and might help to slightly improve skin firmness, potentially reducing lines and wrinkles
