What the product description says
“A rich Hyaluronic Acid Complex helps to instantly hydrate your skin while locking in moisture for long-term results.”
Source: Lookfantastic

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, hyaluronic acid.

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: chondrus crispus extract, carthamus tinctorius seed oil.

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

PanthenolHero· HumectantEffect: HighHelps attract water to the upper layer of the skin and can help improve skin barrier function~0.35–0.8%
MadecassosideHeroEffect: HighAn antioxidant that is typically derived from plant Centella Asiatica. It can help neutralize free radicals in skin and support skin barrier function. It could, however, itself be irritating. It is often unstable in formulations~0.3–0.7%
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~3.8–5.7%
Carthamus tinctorius seed oilKey active· EmollientEffect: HighAn emollient that helps soften the skin and might help calm down inflammation~3.7–5.5%
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~0.8–1.25%
Sodium hyaluronateKey active· HumectantEffect: HighOne of the best moisturizing ingredients. Attracts water into the upper layer of the skin~0.5–1.15%
Sodium pcaKey active· HumectantEffect: HighNaturally present in skin and helps to attract water to its upper layer~0.35–0.85%
Saccharomyces/xylinum/black tea fermentKey activeEffect: HighA fermented sweet black tea. There is no studies on particular benefits of this ingredient in skin. It can help attract water to the upper layer of the skin, and might have some anti-oxidant effect. It is used in skincare for mostly marketing purposes because of the popularity of kombucha drinks~0.3–0.7%
Chondrus crispus extractKey active· OcclusiveEffect: HighRed algae extract that helps attract water to the upper layer of the skin and create a nicer product consistency~0.2–0.7%
Hydrolyzed jojoba estersKey activeEffect: HighHelps soften the upper layer of the skin~0.15–0.55%
Sodium lactateKey active· HumectantEffect: HighHelps attract water to the upper layer of the skin. Is often used to adjust the pH level of the product~0.1–0.45%
AllantoinUnder-dosedHelps calm down inflammation in skin and can help reduce itching. Helps to repair the skin barrier and keep skin hydrated~0.15–0.55%
GluconolactoneUnder-dosedA polyhydroxy acid (PHA) that helps shed the dead cells from the skin surface revealing smoother skin. Is believed to be genter than AHAs. It helps attract water to the upper layer of the skin and can stimulate production of skin's own hyaluronic acid resulting in improved hydration levels. It has been shown to be helpful against acne and clogged pores if used consistently (e.g over a period of 12 weeks) in high enough concentration. It can help reduce fine lines and wrinkles and improve skin tone with long-term application. Can help neutralize free radicals~0.1–0.45%

Works well

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

BisabololEffect: LowAn active component of chamomile plant that historically has been used to calm down irritated skin. A recent study shows that bisabolol indeed can have some anti-inflammatory effect on skin, even though conclusive data is lacking. Bisabolol has a sweet floral scent and can be added to products for its aromatic properties~1.2–1.8%
Euterpe oleracea fruit extractEffect: LowA plant extract that can have some anti-oxidant effect in skin~0.3–0.75%
