“This revitalising serum boasts a Matrixyl 3000 peptide with Albizia Julibrissin Bark Extract to stimulate collagen production, helping to combat fine lines and wrinkles.”
This product contains palmitoyl tetrapeptide-7, palmitoyl tripeptide-1. There is some human evidence that these ingredients help reduce and prevent fine lines and wrinkles and improve skin elasticity and firmness, though it is smaller or less consistent than the evidence for the best anti-aging ingredients.

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 oil.
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

Ingredient callouts
- Peptides (palmitoyl tripeptide-1 0.05% - 0.20% and palmitoyl tetrapeptide-7 0.05% - 0.20%). 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 (hyaluronic acid 0.10% - 0.40% and glycerin 4.10% - 6.10%). These ingredients help attract water to the upper layer of the skin and improve the skin hydration.
