What the product description says

“Contains a blend of nourishing ingredients to hydrate skin and improve skin vitality”

Source: Lila Beauty

This product contains good ingredients to attract water to the upper layer of the skin. These ingredients are called "humectants": biosaccharide gum-1, glycerin.

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. If the air is dry, humectants can speed up the moisture loss from the skin. This is why it is a good idea to use another product on top of this one to help "seal in" the moisture (look for ingredients like dimethicone, squalane, oils and butters).

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

PanthenolHero· HumectantEffect: HighHelps attract water to the upper layer of the skin and can help improve skin barrier function~0.55–1.25%

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~0.15–0.7%

Biosaccharide gum-1Key active· HumectantEffect: HighHelps attract water to the upper layer of the skin and is claimed to provide a longer-lasting hydration because of its ability to create a water-binding film on the surface of the skin~0.1–0.5%

Hydroxydecyl ubiquinoneKey activeEffect: HighAn analogue of coenzyme Q10 that has a lower molecular weight, which can improve its ability to penetrate the skin. It helps neutralize free radicals in skin, improves skin hydration and might be helpful agains fine lines and wrinkles. It can be an allergen~0.05–0.15%

Bis-peg-18 methyl ether dimethyl silane· Humectant, EmollientEffect: LowA type of silicone that helps soften the upper layer of the skin and create a nice product texture~1.5–2.3%

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~0.4–0.95%

AllantoinUnder-dosedHelps calm down inflammation in skin and can help reduce itching. Helps to repair the skin barrier and keep skin hydrated~0.35–0.8%

Caprylic/capric triglycerideUnder-dosedA good mix of fatty acids that forms a protective layer on the skin. Improves the shelf life of products. Derived from coconut and glycerin~0.1–0.45%

Anti-oxidation

Side benefit · Hydroxydecyl ubiquinone, Calendula officinalis flower extract

Works well

This product contains antioxidants (hydroxydecyl ubiquinone) that can help neutralize free radicals in skin. By doing so, they can lessen the damage the skin gets from the UV light (sun).

Anti-aging

Side benefit · Hydroxydecyl ubiquinone

May help

This product contains hydroxydecyl ubiquinone. 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.
