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, 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: 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

Typically has large molecule size unless advertised otherwise on the product label. Helps support skin's barrier function and may help to reduce inflammation~0.9–1.15%
Cetearyl alcoholKey active· EmollientEffect: MediumA non-drying alcohol. Works as an emollient. Helps water and oil mix together and creates a nice product texture~1.7–2%

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-8Key activeEffect: MediumA type of peptide. Peptides are excellent moisturizers and might be able support collagen production reducing fine lines and wrinkles~0.65–0.95%

Typically has large molecule size unless advertised otherwise on the product label. Helps support skin's barrier function and may help to reduce inflammation~0.9–1.15%
Sodium ascorbyl phosphateEffect: LowA stable derivative of vitamin C. It is oil-soluble which means it is more likely to penetrate the skin compared to the pure form of vitamin C (which is water-soluble), but it is less bio-available and is way less effective in stimulating collagen and reducing wrinkles compared to the pure form of vitamin C (L-ascorbic acid) and its other derivatives (for example, magnesium ascorbyl phosphate). At the same time, this vitamin C derivative has been shown in studies to be effective in reducing acne, blemishes and clogged pores. It is less irritating then the pure form of vitamin C~0.3–0.6%
Centella asiatica extractUnder-dosedEffect: MediumA 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.

It can be itself be irritating though.~0.25–0.5%
Retinyl palmitateUnder-dosedEffect: MediumThree 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~0.15–0.3%
TocopherolEffect: Low, below effective dosePure form of vitamin E. Can help moisturise and protect the skin from free radicals. Often used to help stabilise other ingredients or the formula itself~0.2–0.35%

This product contains antioxidants (arbutin, sodium ascorbyl phosphate) 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.

Product summary

Based on the ingredients included, "111SKIN - Celestial Black Diamond Eye Cream by 111skin" works well for moisturizing the skin. This moisturizer uses a good combo of humectants and emollients. These both types of ingredients are essentials for improving the skin hydration and keeping the skin barrier healthy. Humectants in this product (acetyl hexapeptide-8, glycerin, hyaluronic acid 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). Emollients in this formulation (isopropyl myristate, oryza sativa bran oil, caprylic/capric triglyceride, cetearyl alcohol and hydrogenated palm oil) help to reduce the moisture loss from the skin. They also soften the skin surface and relieve the feeling of dryness and tightness.

Ingredient callouts

  • this moisturizer includes a form of retinoids (vitamin A) - retinyl palmitate 0.15% - 0.30%, 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.
  • We like that this moisturizer contains peptides (acetyl hexapeptide-8 0.65% - 0.95%). There are many different kind of peptides and they are naturally present in our skin. They all are a combination of amino-acids. Some of them work as natural anti-biotics, promote wound-healing and production of collagen. The science is still not settled on how effective peptides in skincare are, but it is very likely that they have a benefit. Peptides 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.

Irritation risk
