“Encapsulated hyaluronic acid is consistently delivered to the skin via a controlled, time-release system – so skin remains hydrated and nourished throughout the night – while silanols (organic molecules with an important role in skin regeneration), optimise fibroblast proliferation and activation of collagen production.”
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:
dextran, 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: dimethicone, cyclopentasiloxane.
The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: acetyl tetrapeptide-2, trifluoroacetyl tripeptide-2
Anti-aging2 ingredients credited for this claimModerate support
“Harnessing some of the latest discoveries in anti-ageing innovation, Zelens’ Stem Complex Rejuvenating Overnight Treatment quickly, cumulatively and phenomenally alters the quality of your complexion.”
This product contains acetyl tetrapeptide-2, trifluoroacetyl tripeptide-2. These ingredients might be able to help reduce and prevent fine lines and wrinkles, improve skin elasticity and firmness, but there is not enough evidence that it actually works.
