This product could be helpful for: Evens skin tone, but its actives are not the most effective or are not well-studied.
Ingredient callouts
- This product also contains Vitamin C (Ascorbic Acid) 3.50% - 5.30% It can be helpful in stimulating collagen production, neutralizing free radicals in skin and improving pigmentation marks. We recommend to use up this product quickly after opening: Ascorbic Acid degrades fast when it gets in contact with air and light. The moment the product turns orange, it is a sign that a significant share of the vitamin C in it is no longer effective.
- Peptides (palmitoyl tetrapeptide-7 0.15% - 0.55% and palmitoyl tripeptide-1 0.15% - 0.65%). 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.
- Adenosine 0.35% - 0.80%. It is a compound that in involved in many biological processes inside the skin cells. According one high-quality clinical trial, topical Adenosine in low concentrations can somewhat help improve "deep wrinkles" - the wrinkles that appear with age in places where our faces are most dynamic (for example, on the forehead or in the corners of the eyes).
- Humectants (hydrolyzed hyaluronic acid 0.35% - 0.80% and glycerin 4.40% - 6.70%). These ingredients help attract water to the upper layer of the skin and improve the skin hydration.

Anti-aging
What does the product description say?
Skin Type Normal Skincare Concerns Dark Circles, Fine Lines and Wrinkles, and Puffiness Formulation Lightweight Cream Highlighted Ingredients , Pure Vitamin C 10% Visibly smooths lines and brightens the under-eye area.

This product can help reduce and prevent fine lines and wrinkles, improve skin elasticity and firmness because it contains adenosine.
These ingredients in the product can also be helpful, even though there is less evidence for their effectiveness: palmitoyl tetrapeptide-7, palmitoyl tripeptide-1.
Keep in mind that it typically takes at least 6 weeks to notice any results because the changes that are needed to improve fine lines and elasticity happen in the deeper layers of the skin. No topical anti-aging product can “erase” wrinkles or fully reverse signs of aging.
Might help improve cell turnover and reduce inflammation in skin. One study shows that the ingredients might be able to help reduce dynamic wrinkles (for example, in the corners of the eyes or on the forehead)

Moisturizing
What does the product description say?
With a lightweight, layerable texture, this cream instantly smooths and hydrates to help refresh the appearance of tired-looking, strained eyes.
Source: Sephora CA
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 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: dimethicone, cyclohexasiloxane.
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

Anti-oxidation
