What the product description says

“This essence helps to boost skin radiance by providing rich nourishment.”

Source: Yesstyle

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: arginine, erythritol.

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: arginine, glycine soja seed extract.

The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: niacinamide, panthenol

Anti-aging

Side benefit · Niacinamide, Serine + 4 more

Works well

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

These ingredients in the product can also be helpful, even though there is less evidence for their effectiveness: 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.

Evens skin tone

Side benefit · Niacinamide, Glycine soja seed extract + 1 more

Works well

This product can help reduce hypepigmentation and even out the skin tone because it contains the following effective ingredients: niacinamide

The following ingredient (ingredients) in this product might be helpful, but there is no evidence to confirm that it actually can help even out the skin tone: glycine soja seed extract.

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.

Ingredient callouts

A good concentration of Niacinamide (2.20% - 2.70%). Niacinamide is a well-studied multi-tasking active. It is stable, and can work well in almost any hydrating formulation. There is solid evidence that Niacinamide can help support skin barrier, regulate oil production and reduce acne and clogged pores. It also helps to fight photodamage and improve the skin tone, reducing pigmentation marks.
Adenosine 0.20% - 0.35%. 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).
Panthenol (pro-vitamin B5) at about 0.70% - 1.00% concentration. In this concentration, Panthenol works effectively to improve the skin barrier and reduce inflammation.
Humectants (arginine 0.15% - 0.30%, lactobacillus ferment 0.15% - 0.30%, sodium hyaluronate 0.15% - 0.30%, erythritol 0.10% - 0.25%, imperata cylindrica root extract 0.15% - 0.25%, saccharomyces ferment filtrate 0.20% - 0.40%, saccharide isomerate 0.25% - 0.50%, panthenol 0.70% - 1.00% and glycerin 3.00% - 3.60%). These ingredients help attract water to the upper layer of the skin and improve the skin hydration.
