Product summary

Judging from the ingredient list, "Sisley-Paris - Neck Cream" works well for improving skin hydration As we expect from a proper moisturizer, the formula includes a combo of effective humectants and emollients. These are the two different types of ingredients that are essential for improving the skin hydration and supporting a healthy skin barrier. Humectants in this product (panthenol, glycerin, glycine soja protein and butylene glycol) help to increase the water content in the upper layer of the skin. (These ingredients do so by "capturing" water molecules from the outside air or from within the deeper layers of the skin). Butyrospermum parkii butter, dimethicone, helianthus annuus seed oil, cetyl alcohol and glycine soja protein in this product help decrease the water evoporation from the skin, so that it stays hydrated for longer. These ingredients also soften the skin and take away the feeling of tightness and dryness.

Product claims breakdown

Moisturizing

6 ingredients contribute at the levels below

Strong evidence

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, glycine soja protein.

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: butyrospermum parkii butter, dimethicone.

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

Anti-aging

1 ingredient contributes at the levels below

Partial evidence

This product does not contain ingredients that are able to reduce fine lines and wrinkles or help with skin elasticity, but it can improve the look of the skin temporarily through moisturization. Well-moisturized skin might also be able to repair the sun damage better.These ingredients - butyrospermum parkii butter, glycine soja protein - could be helpful for preventing or repairing signs of aging in theory, but there is no evidence that it actually works.
