“Combining incredible coverage with light-scattering pearls to detract from the signs of fatigue so you look wide awake and refreshed (when youre anything but), this incredible formula blends effortlessly to counteract shadows and soften the look of fine lines.”
This product contains palmitoyl oligopeptide, palmitoyl tetrapeptide-7. 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.
MoisturizingSide benefit · Palmitoyl tetrapeptide-7, Palmitoyl oligopeptide + 8 moreWorks well
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, hydrolyzed collagen.
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: bis-diglyceryl polyacyladipate-2, caprylic/capric triglyceride.
The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: palmitoyl oligopeptide, palmitoyl tetrapeptide-7
Anti-oxidationSide benefit · Chrysin, Ascorbyl palmitate + 3 moreMay help
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.
Evens skin toneSide benefit · Chrysin, N-hydroxysuccinimide + 3 moreMay help
The following ingredient (ingredients) in this product might be helpful, but there is no evidence to confirm that it actually works: chrysin.

Three steps removed from the active form of vitamin A - retinoic acid. To have an effect in the skin, it first needs to be converted twice to become the retinoic acid. This means it is less potent than retinol, but could also be less irritating. Once converted to the retinoic acid in the skin, it helps against all signs of aging, improves skin cell turnover and helps fight blemishes and clogged pores. However, in many cosmetic formulations, it is used in a concentration that is too low to have the full effect

Ingredient callouts
- this product includes a form of Retinoids (vitamin A) - retinyl palmitate 0.10% - 0.50%, but this type of vitamin A is not very effective. It could in theory help with fine lines and wrinkles, but the effect is most likely minimal.
- Peptides (palmitoyl tetrapeptide-7 0.20% - 0.75% and palmitoyl oligopeptide 0.15% - 0.60%). Peptides are a very big group of ingredients. They all consist of a different combination of aminoacids. Our skin produces Peptides naturally. Some of them work as natural antibiotics, promote wound-healing and production of collagen. The scientists are still studying how effective the topical application of Peptides is, but it is very likely that theynare helpful. Peptides might be able to support skin barrier restoration and even have an anti-aging benefit. At the very least, they certainly help attract water to the skin and support the hydration in this way.
- Humectants (hydrolyzed collagen 0.35% - 0.80%, sodium hyaluronate 0.10% - 0.45% and glycerin 0.35% - 0.80%). These ingredients help attract water to the upper layer of the skin and improve the skin hydration.
