What the product description says
“Dark Circles, Puffiness & Lines Eye Serum | SKIN Functional”
From product name

This product can help reduce and prevent fine lines and wrinkles, improve skin elasticity and firmness because it contains acetyl glucosamine.

These ingredients in the product can also be helpful, even though there is less evidence for their effectiveness: acetyl hexapeptide-8, acetyl tetrapeptide-5, dipeptide-2, palmitoyl tetrapeptide-7, palmitoyl tripeptide-1, palmitoyl tripeptide-38.

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.

Acetyl tetrapeptide-5Key activeEffect: MediumA type of peptide. Peptides are excellent moisturizers and might be able support collagen production reducing fine lines and wrinkles~1.7–2.5%
Dipeptide-2Key activeEffect: MediumA type of peptide. Peptides are excellent moisturizers and might be able support collagen production reducing fine lines and wrinkles~1.4–2.1%
Acetyl hexapeptide-8Key activeEffect: MediumA type of peptide. Peptides are excellent moisturizers and might be able support collagen production reducing fine lines and wrinkles~1.2–1.9%

Palmitoyl tripeptide-38Key activeEffect: MediumA type of peptide. Peptides are excellent moisturizers and might be able support collagen production reducing fine lines and wrinkles~0.35–0.8%
Acetyl glucosamineKey activeEffect: HighAn effective moisturizing ingredient that also has been shown to be effective in evening out the skin tone and reducing hyperpigmentation. It can help somewhat reduce wrinkles in skin~0.1–0.45%
Aminobutyric acidEffect: LowHas been shown to support wound healing and skin barrier function when used topically in rats. Is likely to be effective in supporting skin's hydration and barrier function, but research for human skin is missing. Might have some anti-aging properties but the research is missing~0.15–0.65%
Ascorbic acidUnder-dosedThe most well-researched antioxidant that works in skin. Helps neutralize free radicals supporting collagen production, helping to even out the skin tone and preventing early signs of aging~0.1–0.5%

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: aminobutyric acid, betaine.

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.

The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: acetyl glucosamine, acetyl hexapeptide-8, acetyl tetrapeptide-5, dipeptide-2, palmitoyl tetrapeptide-7, palmitoyl tripeptide-1, palmitoyl tripeptide-38

Works well

This product can help reduce hypepigmentation and even out the skin tone because it contains the following effective ingredients: acetyl glucosamine, glutathione

Keep in mind that you would need to apply any topical skincare targetted at hypigmentation consistently for a couple of months to get a result. No topical skincare product can help get rid of hyperpigmentation (including post-acne marks and age spots) instantly.
