What the product description says
“Combined with moisturizing and overflowing elasticity.”
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: glycerin, hydrolyzed collagen.

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: cholesterol, hydrolyzed collagen.

The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: palmitoyl pentapeptide-4

Palmitoyl pentapeptide-4HeroEffect: HighA type of peptide. Peptides are excellent moisturizers and might be able support collagen production reducing fine lines and wrinkles~0.05–0.2%
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~2.6–4%
AdenosineKey activeEffect: MediumMight help improve cell turnover and reduce inflammation in skin. One study shows that the ingredients might be able to help reduce dynamic wrinkles (for example, in the corners of the eyes or on the forehead)~1.5–2.3%
Hydrolyzed collagenKey active· Humectant, EmollientEffect: HighA typically plant-derived compound that is supposed mimic human collagen. Cannot penetrate the skin barrier so is not particularly useful in skincare products beyond attracting water to the upper layer of the skin~0.1–0.3%
CholesterolKey active· EmollientEffect: HighAn emollient that is naturally found in skin~0.05–0.15%
Elaeis guineensis oilKey active· EmollientEffect: MediumHelps soften the upper layer of the skin~0.05–0.2%
Oryza sativa bran oilKey active· EmollientEffect: HighHelps soften the upper layer of the skin and might have some anti-oxidant properties~0.01–0.1%
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~4.5–6.7%
Pentylene glycol· EmollientEffect: LowUsed to preserve products, dissolve other ingredients and create a nice product texture~0.05–0.25%
AlginEffect: LowUsed to thicken product formulation. Can help attract water to the upper layer of the skin~0.05–0.15%
Ethyl oleate· EmollientEffect: LowEthyl oleate is a long-chain fatty acid ethyl ester resulting from the formal condensation of the carboxy group of oleic acid with the hydroxy group of ethanol. It derives from an oleic acid. In skincare, it is used to soften the upper layer of the skin, improve the product texture and smell~0.01–0.05%
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~0.1–0.3%
LecithinEffect: Low, below effective doseUsed mostly for creating emulsions - helping oil and water mix together. Helps soften the upper layer of the skin~0.05–0.2%

Anti-aging
Side benefit · Adenosine, Tocotrienols + 3 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 pentapeptide-4, tocotrienols.

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.

AdenosineKey activeEffect: HighMight help improve cell turnover and reduce inflammation in skin. One study shows that the ingredients might be able to help reduce dynamic wrinkles (for example, in the corners of the eyes or on the forehead)~1.5–2.3%

Polygonum bistorta root extractEffect: LowA plant extract that might have some anti-oxidant properties and is claimed by its manufacturer to be able to decrease lines and wrinkles but evidence is lacking~1.2–1.7%

Product summary

"Kose - DECORTE AQ Lotion ER" has a good moisturizing formula. To work well, any moisturizer needs to include a combination of water-binding and emollient ingredients. Kose - DECORTE AQ Lotion ER ticks this box. Glycerin, hydrolyzed collagen and butylene glycol 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). Hydrolyzed collagen, oryza sativa bran oil, elaeis guineensis oil, ethyl oleate and pentylene glycol in this product help decrease the water evoporation from the skin, so that it stays hydrated for longer. These ingredients also soften the skin and take away the feeling of tightness and dryness.

Ingredient callouts

  • We like that this moisturizer contains peptides (palmitoyl pentapeptide-4 0.20% - 0.75%). 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. Peptides 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 1.50% - 2.30%. It is a compound that in involved in many biological processes inside the skin cells. According one high-quality clinical trial, topical Adenosine in low concentrations can somewhat help improve "deep wrinkles" - the wrinkles that appear with age in places where our faces are most dynamic (for example, on the forehead or in the corners of the eyes).
This product contains ingredients that could be beneficial, but their concentrations are too low in this formulation: sodium lactate, lecithin and vitamin e
