Ceramides (ceramide np 0.20% - 0.80%). Ceramides are an important part of our natural skin barrier. The Ceramides used in skincare are synthetic or come from plants. They help soften the skin and can help "fill the gaps" in the skin barrier, keeping the skin hydrated and resilient for longer.
Peptides (copper tripeptide-1 0.10% - 0.30%). There are many different kind of Peptides and they are naturally present in our skin. They all are a combination of aminoacids. Some of them work as natural antibiotics, promote wound-healing and production of collagen. The science is still not settled on how effective Peptides are in skincare, but it is very likely that they have a benefit. They 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.
Adenosine 0.40% - 0.90%. 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).
In addition, this product contains Allantoin (0.50% - 1.20%). Allantoin is helpful in wound-healing and can help restore the skin barrier faster. It might also be able to improve scars, but the evidence is not very strong for this.
Humectants (sodium hyaluronate 1.40% - 2.10%, betaine 1.60% - 2.40%, hydrolyzed collagen 2.60% - 4.00% and glycerin 3.80% - 5.80%). These ingredients help attract water to the upper layer of the skin and improve the skin hydration.

What can the product work for?

Anti-aging

What does the product description say?

Restore bounce and luster in skin with this rejuvenating toner starring the antioxidant astaxanthin to improve skin elasticity and smooth fine lines and wrinkles.

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: astaxanthin, copper tripeptide-1.

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 0.4% - 0.9%

Irritation risk:

Concentration: Effectiveness: HIGH

Might help improve cell turnover and reduce inflammation in skin. One study shows that the ingredients might be able to help reduce dynamic wrinkles (for example, in the corners of the eyes or on the forehead)

astaxanthin 2% - 3%

Irritation risk:

Concentration: Effectiveness: MEDIUM

Helps neutralize free radicals in skin and might help to calm down inflammation

copper tripeptide-1 0.1% - 0.3%

Irritation risk:

Concentration: Effectiveness: MEDIUM

A naturally occurring peptide. One of the most studied peptides in dermatology. It is sometimes abbreviated GHK-Cu. Belongs to the class of carrier peptides. It stimulates both synthesis and breakdown of collagen in skin. It is released in skin wounds and inflammation to support healing. It accelerates wound-healing of the skin and can stimulate hair growth. There are preliminary studies that confirm that copper tripeptide can help support collagen production reducing fine lines and wrinkles and decrease inflammation in skin.

Moisturizing

What does the product description say?

Enriched with green tea callus culture extract, the toner moisturizes skin and protects it from external aggressors to promote healthy and balanced 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: betaine, glycerin.

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: squalane, hydrolyzed collagen.

The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: ceramide np, copper tripeptide-1

hydrolyzed collagen 2.6% - 4%

Irritation risk:

Concentration: Effectiveness: HIGH

A typically plant-derived compound that is supposed mimic human collagen. Cannot penetrate the skin barrier so is not particularly useful in skincare products beyond attracting water to the upper layer of the skin

sodium hyaluronate 1.4% - 2.1%

Irritation risk:

Concentration: Effectiveness: HIGH

One of the best moisturizing ingredients. Attracts water into the upper layer of the skin

squalane 0.1% - 0.4%

Irritation risk:

Concentration: Effectiveness: HIGH

An oil naturally present in skin. Works as an emollient to soften the skin and form a protective layer on its surface without a greasy feeling.

Anti-oxidation

This product contains antioxidants (astaxanthin) that can help neutralize free radicals in skin. By doing so, they can lessen the damage the skin gets from the UV light (sun).

The following ingredients - punica granatum extract also can have an antioxidant effect, but there is less evidence to confirm their effectiveness in skin.

astaxanthin 2% - 3%

Irritation risk:

Concentration: Effectiveness: HIGH

Helps neutralize free radicals in skin and might help to calm down inflammation

punica granatum extract 0.1% - 0.35%

Irritation risk:

Concentration: Effectiveness: MEDIUM

A plant extract that can help neutralize free radicals in skin and even out the skin tone, but is typically used in products in a concentration that is too low to be effective

trifolium pratense flower extract 0.1% - 0.4%

Irritation risk:

Concentration: Effectiveness: LOW

Red clover flower extract. Can contain anti-oxidants but also potential irritant compounds
