What the product description says
“Hydrating Serum Hyaluronic Acid”
From product name

This product contains good ingredients to attract water to the upper layer of the skin. These ingredients are called "humectants": betaine, 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~1.4–2.2%
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~3.9–5.9%
Sodium hyaluronateKey active· HumectantEffect: HighOne of the best moisturizing ingredients. Attracts water into the upper layer of the skin~2.6–3.9%
BetaineKey active· HumectantEffect: HighHelps attract water to the upper layer of the skin and improves the product texture~1–1.5%

Hydrogenated starch hydrolysateKey active· HumectantEffect: MediumHelps to attract water to the upper layer of the skin. Can add sweet taste to lip products~0.45–1.05%
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~1.9–2.9%
Pentylene glycol· EmollientEffect: LowUsed to preserve products, dissolve other ingredients and create a nice product texture~0.4–0.95%
Cucumis sativus fruit extractEffect: Low, below effective doseMight be somewhat helpful in reducing hyperpigmentation and neutralizing free radicals but its typical concentration in a product is too low for having an effect~0.05–0.25%
