What the product description says

“Combines Peptide and Hyaluronic Acid to hydrate the skin and help deliver active ingredients.”

Source: Lila Beauty

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: dimethicone, squalane.

The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: acetyl hexapeptide-8, ceramide np, palmitoyl pentapeptide-4, palmitoyl tripeptide-5, panthenol, urea

Strong evidence

What the product description says

“Rejuran Intensive Eye Cream improves eye concerns such as wrinkles, elasticity, and dullness.”

Source: Lila Beauty

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: acetyl hexapeptide-8, palmitoyl pentapeptide-4, palmitoyl tripeptide-5, serine.

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.

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~0.2–0.4%

BisabololEffect: Low, below effective doseAn active component of chamomile plant that historically has been used to calm down irritated skin.

Product summary

"Rejuran - Buy Rejuran Intensive Eye Cream in Australia - Korean Skincare Online" has a good moisturizing formula. 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, urea, glycerin, hyaluronic acid and sodium hyaluronate) 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). Ceramide np, cholesterol, dimethicone, ricinus communis seed oil and squalane 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 0.20% - 0.40%, 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.
As a plus, this moisturizer also contains Ceramides (ceramide np 0.20% - 0.35%). Ceramides are a type of lipids that our skin produces itself. They are a building block of the skin's barrier. Ceramides used in skincare are synthetic or extracted from plants. They work well for softening the skin surface and "patch holes" in the skin's barrier.
This moisturizer also contains Peptides (palmitoyl pentapeptide-4 0.20% - 0.40%, acetyl hexapeptide-8 0.20% - 0.40% and palmitoyl tripeptide-5 0.20% - 0.40%). 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 they are 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 0.20% - 0.40%. It is a chemical present inside our skin cells. A clinical trial confirmed that topical application of Adenosine in a low concentration can reduce dynamic wrinkles (these are the wrinkles that appear with age in a places where our mimic is the most active, for example, in the corners of the eyes or on the forehead).

This product contains ingredients that could be beneficial, but their concentrations are too low in this formulation: butyrospermum parkii butter and niacinamide
