What the product description says
“Added Hyaluronic Acid supports hydration, helping maintain skin comfort while targeting oily and congested areas.”

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: glycerin, hyaluronic acid.

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: squalane, glycine soja sterols.

The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: niacinamide, panthenol

This product can help reduce hypepigmentation and even out the skin tone because it contains the following effective ingredients: niacinamide

Keep in mind that you would need to apply any topical skincare targetted at hypigmentation consistently for a couple of months to get a result. No topical skincare product can help get rid of hyperpigmentation (including post-acne marks and age spots) instantly.

    Hum ... Ce produit est recommandé pour les peaux mixtes à grasses, afin de contrôler l'exes de sébum et les boutons d'acné

    Mais j'ai l'impression que ce produit accentue mon acné....

    Je trouve la texture un peu trop épaisse, pas très agréable à utiliser.
