What the product description says
“Peptides visibly firm and tighten skin while probiotics provide energized complexion.”
Source: Skinstore

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

These ingredients in the product can also be helpful, even though there is less evidence for their effectiveness: palmitoyl hexapeptide-14, palmitoyl tripeptide-37.

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.

NiacinamideKey activeEffect: 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~2.3–2.9%
Palmitoyl tripeptide-37Key activeEffect: Medium~1.1–1.4%
Palmitoyl hexapeptide-14Key activeEffect: Medium~0.8–1.2%
Aloe barbadensis leaf juiceEffect: LowTraditionally used to treat sunburns, dermatitis and inflammation, but evidence for its effectiveness is lacking. The extract can contain humectants that help attract water into the skin~7.3–9%
Lycium barbarum fruit extractEffect: Low, below effective doseA plant extract that can help neutralize free radicals in skin and attract water to its upper layer~0.35–0.65%

What the product description says
“This lightweight hydrating serum replenishes the skin's moisture barrier.”
Source: Skinstore

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

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, palmitoyl hexapeptide-14, palmitoyl tripeptide-37

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.
