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, butylene glycol.

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: helianthus annuus seed oil, limnanthes alba seed oil.

GlycerinKey activeEffect: HighOne of the best moisturizing ingredients. Naturally present in skin. It attracts water to the upper layer of the skin working as a humectant~3.4–5.1%
Limnanthes alba seed oilKey activeEffect: HighThis oil's cmposition is closest to rapeseed oil. It is a very stable oil and serves as an emoillient~1.3–1.9%
Helianthus annuus seed oilKey activeEffect: HighA great emollient due to its high linoleic acid content. One of the most effective plant oils in helping skin hydration and repairing skin barrier function~0.45–1%
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)~0.35–0.85%
Isononyl isononanoateEffect: LowForms a protective film on the surface of the skin to prevent moisture loss. Gives a velvety feel to products while reducing tackiness~2.8–4.2%
Butylene glycolEffect: 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~2.1–3.1%
Pentylene glycolEffect: LowUsed to preserve products, dissolve other ingredients and create a nice product texture~1.7–2.6%
Palmitic acidEffect: LowAn emollient that is naturally present in skin and helps soften it~0.15–0.65%
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%

This product contains adenosine. This ingredient 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.
