What the product description says

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

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: niacinamide

NiacinamideHeroEffect: HighIs proven to be effective in reducing blemishes, evening out skin tone and helping to improve lines and wrinkles. It helps the skin to repair sun damage, calm down inflammation and keep maintain good levels of moisture. The concentration of about 2% is effective for supporting the skin barrier and evening out the skin tone. Concentration of 4-6% is better for helping with acne and balancing the sebum production~3.6–5.5%
Bacillus fermentKey activeEffect: HighA product of bacterial fermentation. Can help attract water to the upper layer of the skin~0.35–0.85%
Chlorella vulgaris extractKey activeEffect: MediumA plant extract that can help to attract water to the upper layer of the skin and might have some anti-oxidant and anti-inflammatory properties~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~0.2–0.75%
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~2.7–4%
Isostearyl neopentanoate· EmollientEffect: LowUsed to create a nice product texture and helps soften the upper layer of the skin. Could be comedogenic~2.1–3.2%
Glyceryl caprylate· EmollientEffect: LowAn emollient that can also help water and oil mix together, as well as prevent bacteria growth in products~0.1–0.45%
Evens skin tone
Side benefit · Niacinamide
Works well

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

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.

Anti-aging
Side benefit · Niacinamide, Magnesium aluminum silicate
Works well

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

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.
