What the product description says

“A hydrating and firming ampoule infused with Pea Extract that helps rejuvenate skin.”

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, 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: arginine, caprylic/capric triglyceride.

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

PanthenolHero· HumectantEffect: HighHelps attract water to the upper layer of the skin and can help improve skin barrier function~0.15–0.65%

GlycerinKey active· HumectantEffect: HighOne of the best moisturizing ingredients. Naturally present in skin. It attracts water to the upper layer of the skin working as a humectant~3.3–5%

BetaineKey active· HumectantEffect: HighHelps attract water to the upper layer of the skin and improves the product texture~2–2.9%

TrehaloseKey active· HumectantEffect: HighA sugar that attracts water to the upper layer of the skin~1.6–2.4%

Caprylic/capric triglycerideKey active· Emollient, OcclusiveEffect: HighA good mix of fatty acids that forms a protective layer on the skin. Improves the shelf life of products. Derived from coconut and glycerin~1.4–2.1%

Sodium hyaluronateKey active· HumectantEffect: HighOne of the best moisturizing ingredients. Attracts water into the upper layer of the skin~1.1–1.7%

Lactobacillus/soybean ferment extractKey activeEffect: MediumA fermentation product created by bacteria Lactobacillus out of soybean. The fermented product helps to attract water to the upper layer of the skin and has anti-bacterial properties.

It can be itself be irritating though.~0.15–0.55%

AllantoinUnder-dosedHelps calm down inflammation in skin and can help reduce itching. Helps to repair the skin barrier and keep skin hydrated~0.15–0.65%

Anti-aging

Centella asiatica extract, Adenosine

Works well

What the product description says

“Strengthens the skin barrier and improve skin elasticity to prevent the signs of aging.”

Source: Yesstyle

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: centella asiatica extract.

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.

Adenosine 0.05% - 0.25%. 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).
Humectants (arginine 0.10% - 0.35%, sodium hyaluronate 1.10% - 1.70%, trehalose 1.60% - 2.40%, betaine 2.00% - 3.00% and glycerin 3.30% - 5.00%). These ingredients help attract water to the upper layer of the skin and improve the skin hydration.
