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, squalane.

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

Tripeptide-1Hero· EmollientEffect: HighA type of peptide. Peptides are excellent moisturizers and might be able support collagen production reducing fine lines and wrinkles~0.25–0.5%
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~4.3–5.3%
C12-15 alkyl benzoateKey active· EmollientEffect: MediumEnhances the product texture and makes it more spreadable. Helps reduce water loss from the outer layer of skin. Extands the shelf life by preventing bacteria growth~4.1–5.1%
SqualaneKey active· Emollient, OcclusiveEffect: HighAn 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.~3.1–3.8%
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~2.3–2.8%
Sodium hyaluronateKey active· HumectantEffect: HighOne of the best moisturizing ingredients. Attracts water into the upper layer of the skin~1.8–2.2%
Superoxide dismutaseKey activeEffect: HighAn antioxidant enzyme that is naturally present in skin. It can help support skin barrier function and reduce inflammation in skin. It is used in topical medications for inflammatory skin conditions including atopic dermatitis (eczema) and psoriasis. There are three types of natural Superoxide Dismutase in human skin. The compound used in topical treatments and cosmetics are mimics of typically one of these natural variants~1.5–1.8%
UbiquinoneKey activeEffect: HighCoenzyme Q10. It helps neutralize free radicals in skin, improves skin hydration and might be helpful agains fine lines and wrinkles. It can be an allergen~1.1–1.3%
Centella asiatica extractKey activeEffect: HighA plant extract that has been shown to be able to reduce inflammation in skin, support restoration of skin barrier function, as well as support collagen production. Contains active compounds called centelloids: asiaticoside, madecasosside, asiatic acid and madecassic acid. Might be helpful in preventing stretch marks. It can be itself be irritating though.~0.5–0.75%
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~0.3–0.5%
Hydrolyzed soy proteinKey active· HumectantEffect: MediumHelps attract water to the upper layer of the skin. Might have some anti-aging, anti-oxidant, and skin lightening properties, but solid evidence is missing~0.3–0.5%
Hydrolyzed wheat proteinKey active· HumectantEffect: MediumCan help attract water to the upper layer of the skin. Avoid if sensitive to gluten~0.25–0.45%
Dimethicone crosspolymerKey activeEffect: MediumUsed to create a thicker product texture. Helps soften the upper layer of the skin and might be able to prevent moisture loss from its surface~0.2–0.4%
Camellia sinensis leaf extractEffect: LowCan contain potent anti-oxidant compounds (abbreviated ECG, GCG, EGC, and EGCG) that might help protect the skin from free radicals. Can help calm down inflammation and has some anti-bacterial properties. Unfortunately, these antioxidants are unstable and lose their effectiveness very quickly in products. The concentration of the antioxidant compounds in the extract also tends to be low to be effective in topical formulation~0.5–0.75%
C13-14 isoparaffin· EmollientEffect: LowHelps soften the upper layer of the skin, dissolve other ingredients and create a thicker product consistency~0.25–0.45%
Polysilicone-11Effect: LowA silicone that forms a light film on the skin surface helping to bind water and temporarily absorb oils creating a matt and powdery feel~0.2–0.4%
Caprylyl glycol· Humectant, EmollientEffect: LowHelps preserve products and creates a nice product texture~0.15–0.25%
Butylene glycol· HumectantEffect: LowUsed to create a nice product texture and help delivery of other ingredients. Might be somewhat helpful in attracting water to the upper layer of the skin~0.15–0.25%
Ascorbyl tetraisopalmitateEffect: Low, below effective doseA vitamin C derivative. Studies show that is might be effective in reducing hyperpigmentation, but there are no studies confirming that it is effectively converted into the bioavailable form of Vitamin C in skin. It is not clear how this derivative compares in effectiveness to the topical application of bioavailable form of vitamin C (L-ascorbic acid)~0.9–1.1%
Lactic acidUnder-dosedAn exfoliating and moisturizing alpha-hydroxy acid (AHA). Typically causes less irritation than other AHAs, for example, glycolic acid. At high concentrations (about 15%), lactic acid can help reduce lines and wrinkles. Recent studies show that lactic acid can support the "good" bacteria living on skin's surface (healthy skin microbiome)~0.25–0.4%

This product contains antioxidants (dimethylmethoxy chromanol, superoxide dismutase, thioctic acid, ubiquinone) 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 - camellia sinensis leaf extract, centella asiatica extract, ginkgo biloba leaf extract also can have an antioxidant effect, but there is less evidence to confirm their effectiveness in skin.

Bisabolol has a sweet floral scent and can be added to products for its aromatic properties~0.6–0.85%
Tocopheryl acetateEffect: Low, below effective doseA more stable but less bio-available form of vitamin E compared to Tocopherol. Might help moisturize and protect the skin from free radicals, but mostly used in low concentrations to stabilize other ingredients.~0.3–0.6%

Product summary

"Zelens - Intense Defence Antioxidant Serum" is effective for: Moisturizing

This product could be helpful for: Anti-aging, but its actives are not the most effective or are not well-studied.

Ingredient callouts

  • Peptides (tripeptide-1 0.25% - 0.50%). 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.
  • Humectants (sodium hyaluronate 1.80% - 2.20% and glycerin 4.30% - 5.30%). These ingredients help attract water to the upper layer of the skin and improve the skin hydration.
