What the product description says

“Contains Marine Collagen Complex and Blue-green Algae to provide intense hydration and revitalize the 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: aphanizomenon flos-aquae extract, fructooligosaccharides.

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: chondrus crispus extract.

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

Anti-aging

Side benefit · Adenosine, Palmitoyl tripeptide-5 + 1 more

Works well

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.

Anti-oxidation

Side benefit · Aphanizomenon flos-aquae extract, Adenosine + 3 more

May help

This product contains antioxidants (aphanizomenon flos-aquae extract) that might be able to help neutralize free radicals in skin to lessen the damage it gets from the UV light (sun). There is not enough evidence to confirm their effectiveness in skin though.

Ingredient callouts

Peptides (palmitoyl tripeptide-5 0.05% - 0.10%). 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 0.15% - 0.55%. 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 (fructose 0.05% - 0.25%, fructooligosaccharides 0.05% - 0.25%, aphanizomenon flos-aquae extract 0.05% - 0.20% and glycerin 2.00% - 3.00%). These ingredients help attract water to the upper layer of the skin and improve the skin hydration.
