What the product description says
“Rehydrate delivers long-lasting moisture to all skin types.”
Source: Ausceuticals

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, sodium hyaluronate.

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: bis-diglyceryl polyacyladipate-2, cholesterol.

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

PanthenolHero· HumectantEffect: HighHelps attract water to the upper layer of the skin and can help improve skin barrier function~4.3–6.4%
PhytosphingosineHero· EmollientEffect: HighA type of lipid that is naturally present in skin. It might help in repairing skin barrier function and has anti-bacterial effect~0.5–1.15%
Acetyl glucosamineHero· HumectantEffect: HighAn effective moisturizing ingredient that also has been shown to be effective in evening out the skin tone and reducing hyperpigmentation. It can help somewhat reduce wrinkles in skin~0.35–0.85%
Lactobacillus/kelp ferment filtrateKey activeEffect: High~5.2–7.7%
Cassia angustifolia seed polysaccharideKey activeEffect: HighHelps attract water to the upper layer of the skin. Is sometimes referred to as "natural" hyaluronic acid (even though hyaluronic acid is not unnatural and is present in human skin)~3.7–5.5%
CholesterolKey active· EmollientEffect: HighAn emollient that is naturally found in skin~1.4–2.2%
Althaea officinalis root extractKey activeEffect: HighA plant extract that can help attract water to the upper layer of the skin and might help to reduce inflammation~1.1–1.7%
Bis-diglyceryl polyacyladipate-2Key active· Emollient, OcclusiveEffect: HighHelps soften the upper layer of the skin and reduce water loss from its surface~0.4–1%
Sodium hyaluronateKey active· HumectantEffect: HighOne of the best moisturizing ingredients. Attracts water into the upper layer of the skin~0.4–0.9%
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~0.4–0.9%
Cucumis sativus fruit water· HumectantEffect: Low~23–34%
LysolecithinEffect: LowLecithin derivative. It helps oil and water mix together and can enhance penetration of other ingredients. It helps soften the upper layer of the skin~0.2–0.8%
Avena sativa kernel oilUnder-dosedAn effective moisturizing and skin barrier repair ingredient. Helps calm down inflammation and has some anti-oxidant properties~0.55–1.3%
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)~0.1–0.35%

What the product description says
“Protects and restores proper hydration of the skin, helping it to maintain a youthful appearance.”
Source: N/A

This product can help reduce and prevent fine lines and wrinkles, improve skin elasticity and firmness because it contains acetyl glucosamine.

Keep in mind that it typically takes at least 6 weeks to notice any results because the changes that are needed to improve fine lines and elasticity happen in the deeper layers of the skin. No topical anti-aging product can “erase” wrinkles or fully reverse signs of aging.

Acetyl glucosamineKey activeEffect: HighAn effective moisturizing ingredient that also has been shown to be effective in evening out the skin tone and reducing hyperpigmentation. It can help somewhat reduce wrinkles in skin~0.35–0.85%

Not advertised by the brand · Acetyl glucosamine, Lactic acid
Works well

This product can help reduce hypepigmentation and even out the skin tone because it contains the following effective ingredients: acetyl glucosamine

Keep in mind that you would need to apply any topical skincare targetted at hypigmentation consistently for a couple of months to get a result. No topical skincare product can help get rid of hyperpigmentation (including post-acne marks and age spots) instantly.
