“Immediate skin hydration”
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:
betaine, 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: caprylic/capric triglyceride, coco-caprylate/caprate.
The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: palmitoyl tetrapeptide-7
Evens skin tone1 ingredient credited for this claimModerate support
“diminished dark spots”
The following ingredient (ingredients) in this product might be helpful, but there is no evidence to confirm that it actually works: chrysin.
Anti-aging2 ingredients credited for this claimModerate support
“fine lines”
This product contains palmitoyl tetrapeptide-7. This ingredient 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.
Anti-oxidationNot advertised by the brand · 2 ingredients credited for this claimModerate support
This product contains antioxidants (chrysin) that might be able to help neutralize free radicals in skin to lessen the damage it gets from the UV light (sun). There is not enough evidence to confirm their effectiveness in skin though.

This product could be helpful for: Evens skin tone and Anti-aging, but its actives are not the most effective or are not well-studied.
Ingredient callouts
- Peptides (palmitoyl tetrapeptide-7 0.45% - 1.05%). 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 (sucrose 0.15% - 0.65%, sodium hyaluronate 0.30% - 0.75%, glyceryl glucoside 1.20% - 1.90%, betaine 3.50% - 5.30% and glycerin 3.90% - 5.90%). These ingredients help attract water to the upper layer of the skin and improve the skin hydration.
