What the product description says

“MOISTURE COMPLEX: An intensely hydrating complex that uses humectants and polysaccharides to draw water to the dermal layer and bind it in the upper dermis.”

Source: 111skin

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: dextran, fructose.

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: isopropyl myristate, vitis vinifera seed oil.

The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: palmitoyl tetrapeptide-7, palmitoyl tripeptide-1, trifluoroacetyl tripeptide-2, urea

UreaHero· HumectantEffect: HighNaturally present in skin (urea makes up about 7% of natural moisturizing factors in skin). Attracts water to the upper layer of the skin. Also has a positive effect on the skin barrier beyond the humectant action. Can enhance penetration of other ingredients. Is an exfoliating ingredient when used in high concentrations~0.25–0.5%

Palmitoyl tetrapeptide-7Hero· EmollientEffect: HighA type of peptide. Peptides are excellent moisturizers and might be able support collagen production reducing fine lines and wrinkles~0.15–0.3%

Palmitoyl tripeptide-1Hero· EmollientEffect: HighA type of peptide. Peptides are excellent moisturizers and might be able support collagen production reducing fine lines and wrinkles~0.15–0.25%

Trifluoroacetyl tripeptide-2HeroEffect: HighA type of peptide. Peptides are excellent moisturizers and might be able support collagen production reducing fine lines and wrinkles~0.1–0.2%

Vitis vinifera seed oilKey active· EmollientEffect: HighA great emollient that can also have anti-oxidant properties~8.5–10.4%

Isopropyl myristateKey active· EmollientEffect: HighAn emollient that helps soften the skin. Could be comedogenic~4.4–5.4%

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~3.1–3.8%

Cetearyl alcoholKey active· EmollientEffect: MediumA non-drying alcohol. Works as an emollient. Helps water and oil mix together and creates a nice product texture~2.3–2.9%

Sodium lactateKey active· HumectantEffect: HighHelps attract water to the upper layer of the skin. Is often used to adjust the pH level of the product~1.1–1.3%

Sodium pcaKey active· HumectantEffect: HighNaturally present in skin and helps to attract water to its upper layer~0.75–1.15%

FructoseKey active· HumectantEffect: HighHelps attract water to the upper layer of the skin~0.3–0.55%

GlycineKey active· HumectantEffect: HighHelps to attract water to the upper layer of the skin and can help restore the skin barrier function~0.3–0.55%

InositolKey active· HumectantEffect: High~0.25–0.45%

DextranKey active· HumectantEffect: HighHelps attract water to the most upper layer of the skin. Derived from sugar~0.15–0.3%

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~0.65–0.95%

TocopherolEffect: Low, below effective dosePure form of vitamin E. Can help moisturise and protect the skin from free radicals. Often used to help stabilise other ingredients or the formula itself~0.55–0.85%

NiacinamideUnder-dosedIs proven to be effective in reducing blemishes, evening out skin tone and helping to improve lines and wrinkles. It helps the skin to repair sun damage, calm down inflammation and keep maintain good levels of moisture. The concentration of about 2% is effective for supporting the skin barrier and evening out the skin tone. Concentration of 4-6% is better for helping with acne and balancing the sebum production~0.25–0.45%

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)~0.2–0.4%

What the product description says

“Visible signs of ageing are significantly diminished.”

Source: 111skin

This product contains palmitoyl tetrapeptide-7, palmitoyl tripeptide-1, trifluoroacetyl tripeptide-2. These ingredients might be able to help reduce and prevent fine lines and wrinkles, improve skin elasticity and firmness, but there is not enough evidence that it actually works.

Palmitoyl tripeptide-1Key activeEffect: MediumA type of peptide. Peptides are excellent moisturizers and might be able support collagen production reducing fine lines and wrinkles~0.15–0.25%

Palmitoyl tetrapeptide-7Key activeEffect: MediumA type of peptide. Peptides are excellent moisturizers and might be able support collagen production reducing fine lines and wrinkles~0.15–0.3%

Trifluoroacetyl tripeptide-2Key activeEffect: MediumA type of peptide. Peptides are excellent moisturizers and might be able support collagen production reducing fine lines and wrinkles~0.1–0.2%

Sodium ascorbyl phosphateEffect: Low, below effective doseA stable derivative of vitamin C. It is oil-soluble which means it is more likely to penetrate the skin compared to the pure form of vitamin C (which is water-soluble), but it is less bio-available and is way less effective in stimulating collagen and reducing wrinkles compared to the pure form of vitamin C (L-ascorbic acid) and its other derivatives (for example, magnesium ascorbyl phosphate). At the same time, this vitamin C derivative has been shown in studies to be effective in reducing acne, blemishes and clogged pores. It is less irritating then the pure form of vitamin C~0.6–0.9%

Ingredient callouts

Peptides (trifluoroacetyl tripeptide-2 0.10% - 0.20%, palmitoyl tripeptide-1 0.15% - 0.25% and palmitoyl tetrapeptide-7 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 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 (urea 0.25% - 0.50%, sodium pca 0.75% - 1.15%, sodium lactate 1.10% - 1.30%, inositol 0.25% - 0.45%, glycine 0.30% - 0.55%, glycerin 3.10% - 3.80%, fructose 0.30% - 0.55% and dextran 0.15% - 0.30%). These ingredients help attract water to the upper layer of the skin and improve the skin hydration.
