“This easily absorbed super serum works across multiple layers of the skin, hydrating your skin, helping it appear plump and smooth, while reducing the appearance of fine lines.”
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: palmitoyl tetrapeptide-7, palmitoyl tripeptide-1.
The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: palmitoyl tetrapeptide-7, palmitoyl tripeptide-1

“This easily absorbed super serum works across multiple layers of the skin, hydrating your skin, helping it appear plump and smooth, while reducing the appearance of fine lines.”
This product contains palmitoyl tetrapeptide-7, palmitoyl tripeptide-1. 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.

Ingredient callouts
- Peptides (palmitoyl tripeptide-1 0.10% - 0.30% and palmitoyl tetrapeptide-7 0.10% - 0.35%). There are many different kind of Peptides and they are naturally present in our skin. They all are a combination of aminoacids. Some of them work as natural antibiotics, promote wound-healing and production of collagen. The science is still not settled on how effective Peptides are in skincare, but it is very likely that they have a benefit. They might help restore the skin barrier and fight the signs of aging. At the very least, Peptides work as humectants: they attract water to the upper layer of the skin and improve its hydration.
- Humectants (sodium lactate 0.15% - 0.50%, hyaluronic acid 0.45% - 1.10%, glycerin 2.60% - 4.00% and sodium hyaluronate 3.40% - 5.10%). These ingredients help attract water to the upper layer of the skin and improve the skin hydration.
