What the product description says
“This powerful anti-ageing moisturiser does its job and then some!”
Source: Escentual

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

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)~0.25–0.45%
Glycine soja proteinEffect: LowA plant extract that helps to attract water to the upper layer of the skin and soften it. It might be helpful in neutralizing free radicals. It might be somewhat helpful for evening out the skin tone. It might be able to support elastin production but solid research is lacking~0.25–0.5%
Ascorbyl glucosideUnder-dosedEffect: MediumA vitamin C derivative that is more stable but less potent than pure form of vitamin C. Has a potential to boost collagen production, nutralise free radicals and reduce hyperpigmentation, but the required concentration is likely to be much higher than for the pure form of vitamin C, limiting the ingredient's effectiveness in products~0.2–0.4%
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~0.25–0.45%

What the product description says
“Age Defender Cream Moisturiser”
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, glycine soja protein.

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, dimethiconol.

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~5.7–7%
Hydrolyzed linseed extractKey activeEffect: HighHelps soften the upper layer of the skin~0.2–0.4%

Theobroma cacao seed butterKey active· EmollientEffect: HighHelps soften the upper layer of the skin and can be helpful in restoring the skin barrier function. Might have some anti-oxidant effect~1.2–1.5%
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~4.4–5.3%
DimethiconolKey active· Emollient, OcclusiveEffect: HighA silicone that makes products more spreadable and keeps skin smooth. Helps to add gloss to skin and may visually fill in fine lines/wrinkles for short time~0.25–0.5%

Exfoliation
Not advertised by the brand · 1 ingredient credited for this claim
Strong support

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: capryloyl salicylic acid.

Capryloyl salicylic acidKey activeEffect: High~0.35–0.6%
