What the product description says
“H3O Hydration”
From product name

This product contains good ingredients to attract water to the upper layer of the skin. These ingredients are called "humectants": 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).

InulinKey activeEffect: HighHelps attract water to the upper layer of the skin. Is claimed to support the growth of "good" bacteria in skin (as a "prebiotic"), but the research is lacking~22–33%
Hyaluronic acidKey active· HumectantEffect: HighOne of the best moisturizing ingredients. Attracts water into the upper layer of the skin. Naturally present in skin. Typically has large molecule size unless advertised otherwise on the product label. Helps support skin's barrier function and may help to reduce inflammation~1.7–2.5%
Anti-oxidation
Not advertised by the brand · Resveratrol, Beta vulgaris root extract + 1 more
Strong evidence

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

ResveratrolKey activeEffect: HighHelps neutralize free radicals in skin and might help reduce fine lines and wrinkles, as well as even out the skin tone~1.1–1.6%
Ascorbic acidUnder-dosedEffect: HighThe most well-researched antioxidant that works in skin. Helps neutralize free radicals supporting collagen production, helping to even out the skin tone and preventing early signs of aging~0.4–0.9%
Beta vulgaris root extractEffect: Low, below effective doseA plant extract that might have some antioxidant properties, but mostly used in cosmetics for its color~0.1–0.45%
Anti-aging
Not advertised by the brand · Resveratrol, Hyaluronic acid + 1 more
Moderate evidence

This product contains resveratrol. 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.
