What the product description says
“24 Hour Moisture Repair Cream”
From product name

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, isomalt.

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: caprylic/capric triglyceride, dimethicone.

The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: palmitoyl tripeptide-38

HydroxyprolineKey activeEffect: HighIs helpful in restoring skin barrier function supporting its moisture levels. Is claimed to stimulte collagen production in skin but evidence is lacking~0.2–0.35%
IsomaltKey active· HumectantEffect: HighHelps attract water to the upper layer of the skin~0.25–0.45%
Lactobacillus fermentKey active· HumectantEffect: HighA fermentation product created by bacteria Lactobacillus. The fermented product has anti-bacterial properties and might be helpful in calming down inflammation, but studies are lacking. Helps attract water to the upper layer of the skin. Can be used as a preservative~0.15–0.3%
Palmitoyl tripeptide-38HeroEffect: HighA type of peptide. Peptides are excellent moisturizers and might be able support collagen production reducing fine lines and wrinkles~0.05–0.15%

Vitis vinifera seed oilKey active· EmollientEffect: HighA great emollient that can also have anti-oxidant properties~0.25–0.5%
Salvia hispanica seed extractKey active· EmollientEffect: HighA plant extract that typically contains linolenic and linoleic acids that help soften the upper layer of the skin and can support skin barrier function~0.25–0.5%
Argania spinosa sprout cell extractKey activeEffect: HighPlant stem cell extract. Can help attract water to the upper layer of the skin and might be helpful in neutralizing free radicals~0.15–0.25%
Caprylic/capric triglycerideKey active· Emollient, OcclusiveEffect: HighA good mix of fatty acids that forms a protective layer on the skin. Improves the shelf life of products. Derived from coconut and glycerin~4.2–5.1%
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~1.9–2.4%

GluconolactoneUnder-dosedEffect: HighA polyhydroxy acid (PHA) that helps shed the dead cells from the skin surface revealing smoother skin. Is believed to be genter than AHAs. It helps attract water to the upper layer of the skin and can stimulate production of skin's own hyaluronic acid resulting in improved hydration levels. It has been shown to be helpful against acne and clogged pores if used consistently (e.g over a period of 12 weeks) in high enough concentration. It can help reduce fine lines and wrinkles and improve skin tone with long-term application. Can help neutralize free radicals~0.2–0.4%
Lactic acidUnder-dosedEffect: HighAn 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)~0.25–0.45%
LecithinEffect: Low, below effective doseUsed mostly for creating emulsions - helping oil and water mix together. Helps soften the upper layer of the skin~0.15–0.3%
Camellia sinensis leaf extractEffect: Low, below effective doseCan 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~0.3–0.55%
Anti-aging
Not advertised by the brand · 7 ingredients credited for this claim
Strong support

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

These ingredients in the product can also be helpful, even though there is less evidence for their effectiveness: palmitoyl tripeptide-38.

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.

Glycolic acidKey activeEffect: HighAn alpha-hydroxy acid (AHA) that helps to remove the dead skin cells on the surface of the skin reveling a more even, smoother complexation. It is also able to stimulate collagen production with long-term use. Could help to reduce pore congestion. It can be irritating to the skin. Apply sunscreen daily if using products with glycolic acid~2.3–2.8%

Exfoliation

This product can help exfoliate the skin. In other words, it helps break down the bonds between dead cells on the surface of the skin and speed up the skin turnover. Skin often appears softer and brighter after exfoliation, but overdoing it can result in disrupted skin barrier. The following ingredient is doing the exfoliating job in this product: glycolic acid.

Glycolic acidKey activeEffect: HighAn alpha-hydroxy acid (AHA) that helps to remove the dead skin cells on the surface of the skin reveling a more even, smoother complexation. It is also able to stimulate collagen production with long-term use. Could help to reduce pore congestion. It can be irritating to the skin.

Evens skin tone
Not advertised by the brand · 5 ingredients credited for this claim
Strong support

This product can help reduce hypepigmentation and even out the skin tone because it contains the following effective ingredients: glycolic acid

The following ingredient (ingredients) in this product might be helpful, but there is no evidence to confirm that it actually can help even out the skin tone: albizia julibrissin bark extract.

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.

Glycerin, isomalt, lactobacillus ferment, sodium hyaluronate and sodium pca in this product (humectants) attract water molecules to the upper layer of the skin (the water comes from the outside air or from the deeper layers of the skin if the air is dry). Emollients in this formulation (salvia hispanica seed extract, vitis vinifera seed oil, caprylic/capric triglyceride, dimethicone and squalane) 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

  • This product contains acids (gluconolactone 0.20% - 0.40%, lactic acid 0.25% - 0.45% and glycolic acid 2.30% - 2.80%). Their concentration is low, and they will not have a strong exfoliating effect. Instead, they work to support the skin natural acid mantle and to attract water (as humectants). PHAs (gluconolactone) especially are great for improving skin hydration. They might be even able to stimulate the production of skin's natural humectants and support the healthy skin microbiome.
  • This moisturizer also contains Peptides (palmitoyl tripeptide-38 0.05% - 0.15%). 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.
This product contains ingredients that could be beneficial, but their concentrations are too low in this formulation: lecithin, lactic acid, gluconolactone and allantoin
