What the product description says

“Ultra pigmented for 24 hours of intense colour and hydration”

Source: Feelunique

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: dimethicone, cholesterol.

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

PanthenolHero· HumectantEffect: HighHelps attract water to the upper layer of the skin and can help improve skin barrier function~1.4–2.1%

Ceramide npHero· EmollientEffect: HighA type of lipid similar to ceramides naturally present in skin. Helps to soften the upper layer of the skin and supports the skin barrier function to keep it hydrated. Can help to prevent inflammation in skin~1.3–2%

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~4–5.9%

BetaineKey active· HumectantEffect: HighHelps attract water to the upper layer of the skin and improves the product texture~1.6–2.4%

Sodium hyaluronateKey active· HumectantEffect: HighOne of the best moisturizing ingredients. Attracts water into the upper layer of the skin~1–1.5%

Chlorella vulgaris extractKey activeEffect: MediumA plant extract that can help to attract water to the upper layer of the skin and might have some anti-oxidant and anti-inflammatory properties~0.35–0.8%

Spirulina platensis extractKey activeEffect: MediumAn algae extract. Might help to attract water to the upper layer of the skin and have an anti-oxidant effect~0.3–0.75%

CholesterolKey active· EmollientEffect: HighAn emollient that is naturally found in skin~0.2–0.8%

AdenosineKey activeEffect: MediumMight 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)~0.2–0.75%

DimethiconeKey active· Emollient, OcclusiveEffect: HighA silicone that helps to reduce water loss from the surface of the skin. Can temporarily "fill in" lines and wrinkles, absorb oil, and create a nice product finish~0.15–0.65%

CyclopentasiloxaneKey active· EmollientEffect: MediumA silicone that helps improve the product texture and spreadability. Can absorb oil creating a short-term mattifying effect on the skin~0.15–0.65%

Scutellaria baicalensis root extract· HumectantEffect: LowA plant extract that might contain a compound baicalin that could be helpful in neutralizing free radicals and reducing inflammation in skin. The baicalin concentration in skincare products is often too low for an effective action. Can be used for its fragrant properties~0.4–0.95%

CyclohexasiloxaneEffect: Low, below effective doseA silicone that serves as an emollient. Helps create a nice non-greasy feels~0.15–0.6%

ArginineUnder-dosedAn amino acid that is naturally present in skin and helps keep it hydrated. When used together with AHAs, it can reduce their irritating effect on the skin~0.05–0.2%

Anti-aging

Not advertised by the brand · Adenosine

Works well

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

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.

AdenosineKey activeEffect: HighMight 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)~0.2–0.75%
