What the product description says
“Hyaluronic acid and bifida ferment (a probiotic) are also responsible for the wave of hydration that this serum delivers.”
Source: Cultbeauty

This product contains good ingredients to attract water to the upper layer of the skin. These ingredients are called "humectants": glycerin, hydrolyzed hyaluronic acid.

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).

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~2.3–3.4%
Methyl gluceth-20Key activeEffect: MediumHelps attract water to the upper layer of the skin and soften it~1.8–2.7%
Undaria pinnatifida extractKey activeEffect: HighA seaweed extract that helps attract water to the upper layer of the skin and might have an anti-oxidant effect~1.1–1.6%
Sodium hyaluronateKey activeEffect: HighOne of the best moisturizing ingredients. Attracts water into the upper layer of the skin~0.4–0.95%
Hydrolyzed hyaluronic acidKey activeEffect: HighOne of the best moisturizing ingredients. Attracts water into the upper layer of the skin. A version of it is naturally present in skin~0.35–0.85%
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~2.8–4.3%
Bifida ferment lysateUnder-dosedConsists of remains of dead yeast bacteria cells. Helps to hydrate the skin and reduce irritation. Might has some anti-oxidant effect~0.15–0.55%
Lactic acidUnder-dosedAn exfoliating and moisturizing alpha-hydroxy acid (AHA). Typically causes less irritation than other AHAs, for example, glycolic acid. At high concentrations (about 15%), lactic acid can help reduce lines and wrinkles. Recent studies show that lactic acid can support the "good" bacteria living on skin's surface (healthy skin microbiome)~0.1–0.4%
