Anti-aging8 ingredients credited for this claimStrong support
“Generates firm collagen moisturizing barrier with radiant skin.”
This product can help reduce and prevent fine lines and wrinkles, improve skin elasticity and firmness because it contains adenosine, niacinamide.
These ingredients in the product can also be helpful, even though there is less evidence for their effectiveness: folic acid, hexapeptide-11, lysine, oligopeptide-1, oligopeptide-3.
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.
Moisturizing25 ingredients credited for this claimStrong support
“Generates firm collagen moisturizing barrier with radiant skin.”
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, biosaccharide gum-1.
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, chondrus crispus extract.
The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: hexapeptide-11, niacinamide, oligopeptide-1, oligopeptide-3
Evens skin toneNot advertised by the brand · 1 ingredient credited for this claimStrong support
This product can help reduce hypepigmentation and even out the skin tone because it contains the following effective ingredients: niacinamide
Keep in mind that you would need to apply any topical skincare targetted at hypigmentation consistently for a couple of months to get a result. No topical skincare product can help get rid of hyperpigmentation (including post-acne marks and age spots) instantly.
Anti-blemishNot advertised by the brand · 2 ingredients credited for this claimStrong support

Product summary
Based on the ingredients included, "Serendi Beauty - Sea Water Algae Cream" works well for moisturizing the skin. As we expect from a proper moisturizer, the formula includes a combo of effective humectants and emollients. These are the two different types of ingredients that are essential for improving the skin hydration and supporting a healthy skin barrier. Humectants in this product (arginine, biosaccharide gum-1, glycerin, histidine and hydrolyzed collagen) help to increase the water content in the upper layer of the skin. (These ingredients do so by "capturing" water molecules from the outside air or from within the deeper layers of the skin). Emollients in this formulation (hydrolyzed collagen, arginine, chondrus crispus extract, phenyl trimethicone and c12-15 alkyl benzoate) help to reduce the moisture loss from the skin. They also soften the skin surface and relieve the feeling of dryness and tightness.
Ingredient callouts
- We love that this moisturizer contains a good concentration of niacinamide 1.80% - 2.20%. Niacinamide is a perfect active in a moistruizer because it helps calm down inflamation in skin and support the skin barrier. More than that, it is helpful for most common skin concerns: it helps regulat oil production, help reduce acne and clogged pores, improve skin tone and prevent pigmentation marks. It also helps fight photodamage.
- This moisturizer also contains Peptides (hexapeptide-11 0.10% - 0.15%, oligopeptide-1 0.10% - 0.20% and oligopeptide-3 0.15% - 0.30%). 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 they are 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 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).
