Ceramides (ceramide ng 0.50% - 0.75%). 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 (palmitoyl tripeptide-5 0.40% - 0.60%). 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 theynare 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 0.50% - 0.75%. 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).
Humectants (glycerin 3.10% - 3.80% and sodium hyaluronate 0.45% - 0.65%). These ingredients help attract water to the upper layer of the skin and improve the skin hydration.

Anti-aging

What does the product description say?

You’ll see visibly smoother texture and the appearance of elasticity and firmness in as little as two weeks.

Source: Sephora

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: palmitoyl tripeptide-5.

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.

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, sodium hyaluronate.

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, isocetyl stearate.

The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: ceramide ng, palmitoyl tripeptide-5

sodium hyaluronate 0.45% - 0.65%

Irritation risk:

Concentration: Effectiveness: HIGH

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

isocetyl stearate 1.2% - 1.5%

Irritation risk:

Concentration: Effectiveness: HIGH

An emollient that helps soften the skin

polymethylsilsesquioxane 0.3% - 0.5%

Irritation risk:

Concentration: Effectiveness: HIGH

A silicone that improves product texture and helps dissolve other ingredients. Can form a non-greasy film on the skin to prevent moisture loss

Evens skin tone

What does the product description say?

It also helps to reduce the appearance of fine lines and deep wrinkles and works to enhance the skin’s moisture barrier by locking in essential hydration.

Concentration: Effectiveness: LOW

An emollient that helps soften the skin. Might be somewhat helpful in evening the skin tone.

pisum sativum extract 0.45% - 0.65%

Irritation risk:

Might be helpful in protecting skin collagen and elastin from breaking down but solid research is lacking
