What the product description says

“A highly moisturizing ampoule formulated with 80% of Lacto Moisturizing Ferment™ that delivers deep hydration to dry skin.”

Source: Yesstyle

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: madecassoside, niacinamide, panthenol

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~1–1.45%

PanthenolHero· HumectantEffect: HighHelps attract water to the upper layer of the skin and can help improve skin barrier function~0.15–0.65%

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~0.1–0.45%

Lactobacillus/soybean ferment extractKey activeEffect: MediumA fermentation product created by bacteria Lactobacillus out of soybean. The fermented product helps to attract water to the upper layer of the skin and has anti-bacterial properties. It might be helpful in calming down inflammation and could be helpful in evening out skin tone, but studies are lacking~22–33%

Bifida ferment lysateKey activeEffect: HighConsists of remains of dead yeast bacteria cells. Helps to hydrate the skin and reduce irritation. Might has some anti-oxidant effect~4.8–7.1%

Lactobacillus ferment lysateKey activeEffect: MediumA "broth" with parts of dead cells of lactobacteria. Might be helpful supporting diverse microbiome in skin, but evidence is lacking~4.3–6.5%

Lactococcus ferment lysateKey activeEffect: HighConsists of remains of dead bacteria cells. Is likely helpful in attracting water to the upper layer of the skin. Might be helpful in reducing inflammation and neutralizing free radicals in skin~3.7–5.5%

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~2–2.9%

Alpha-glucan oligosaccharideKey activeEffect: HighHelps attract water to the upper layer of the skin~0.15–0.6%

TriethylhexanoinKey activeEffect: HighHelps soften the upper layer of the skin~0.15–0.5%

AsiaticosideKey activeEffect: HighAn active compound of Centella Asiatica plant extract. In combination with other active compounds of Centella Asiatica extract (madecasosside, asiatic acid and madecassic acid), asiaticoside has been shown to be helpful in wound-healing, restoring skin barrier function and supporting collagen production in skin. It can, however, itself be irritating~0.1–0.35%

LactobacillusKey activeEffect: HighA non-living ingredient made by fermentation with the bacteria Lactobacillus. It can help attract water to the upper layer of the skin and might help reduce inflammation~0.1–0.35%

AdenosineKey activeEffect: MediumMight help improve cell turnover and reduce inflammation in skin. One study shows that the ingredients might be able to help reduce dynamic wrinkles (for example, in the corners of the eyes or on the forehead)~0.1–0.45%

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~2.6–3.9%

Polymnia sonchifolia root juiceEffect: LowA plant extract that helps attract water to the upper layer of the skin and might have some anti-oxidant properties~0.2–0.75%

TocopherolEffect: Low, below effective dosePure form of vitamin E. Can help moisturise and protect the skin from free radicals. Often used to help stabilise other ingredients or the formula itself~0.1–0.35%

Anti-aging

Side benefit · Niacinamide, Centella asiatica leaf extract + 5 more

Works well

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

These ingredients in the product can also be helpful, even though there is less evidence for their effectiveness: asiaticoside, centella asiatica leaf extract, madecassoside.

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.

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.
