"111SKIN - Celestial Black Diamond Eye Cream" has a good moisturizing formula. To work well, any moisturizer needs to include a combination of water-binding and emollient ingredients. 111SKIN - Celestial Black Diamond Eye Cream ticks this box. Humectants in this product (acetyl hexapeptide-8, glycerin, sodium hyaluronate and caprylyl glycol) help to increase the water content in the upper layer of the skin. (These ingredients do so by "capturing" water molecules from the outside air or from within the deeper layers of the skin). Isopropyl myristate, oryza sativa bran oil, caprylic/capric triglyceride, cetearyl alcohol and hydrogenated palm oil in this product help decrease the water evoporation from the skin, so that it stays hydrated for longer. These ingredients also soften the skin and take away the feeling of tightness and dryness.

Ingredient callouts

this moisturizer includes a form of retinoids (vitamin A) - retinyl palmitate 0.30% - 0.55%, 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.
This moistruizer also contains peptides (acetyl hexapeptide-8 0.70% - 1.05%). Peptides is a very big group of ingredients. They all consist of a different combination of amino-acids. Our skin produces peptides naturally. Some of them work as natural anti-biotics, 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 peptides in skincare are helpful. They 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.

Irritation risk

This product contains acetyl hexapeptide-8. 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.

acetyl hexapeptide-8 0.7% - 1.05%

Irritation risk:

Concentration: Effectiveness: MEDIUM

A type of peptide. Peptides are excellent moisturizers and might be able support collagen production reducing fine lines and wrinkles

centella asiatica extract 0.25% - 0.45%

Irritation risk:

Concentration: Insufficient!

A plant extract that has been shown to be able to reduce inflammation in skin, support restoration of skin barrier function, as well as support collagen production. Contains active compounds called centelloids: asiaticoside, madecasosside, asiatic acid and madecassic acid. Might be helpful in preventing stretch marks. It can be itself be irritating though.

retinyl palmitate 0.3% - 0.55%

Irritation risk:

Concentration: Insufficient!

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

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, sodium hyaluronate.

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, isopropyl myristate.

The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: acetyl hexapeptide-8

glycerin 2% - 2.4%

Irritation risk:

Concentration: Effectiveness: HIGH

This product contains ingredients (glycyrrhiza glabra root extract) that could help reduce hyperpigmentation (for example, post-acne marks or age spots) in theory, but there is not enough evidence that they actually work.
