What the product description says
“Exfoliants Tags.”
Source: N/A

This product can help exfoliate the skin. In other words, it helps break down the bonds between dead cells on the surface of the skin and speed up the skin turnover. Skin often appears softer and brighter after exfoliation, but overdoing it can result in disrupted skin barrier. The following ingredient is doing the exfoliating job in this product: mandelic acid.

Mandelic acidKey activeEffect: HighHelps shed the upper layer of dead cells from the surface of the skin revealing smoother, brighter skin. It can help to reduce hyperpigmentation. It has anti-bacterial properties, and might help to reduce blemishes, as well as fine lines and wrinkles. It is considered to be gentler than glycolic acid~1.4–2%
AllantoinEffect: LowHelps calm down inflammation in skin and can help reduce itching. Helps to repair the skin barrier and keep skin hydrated~1.7–2.6%
Evens skin tone

What the product description says
“00 This skin-perfecting system clears congested pores, improves uneven skin tone, and reduces the appearance of fine lines and blemishes.”
Source: N/A

This product can help reduce hypepigmentation and even out the skin tone because it contains the following effective ingredients: alpha-arbutin, mandelic acid

The following ingredient (ingredients) in this product might be helpful, but there is no evidence to confirm that it actually can help even out the skin tone: glycyrrhiza glabra root extract.

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.

Mandelic acidKey activeEffect: HighHelps shed the upper layer of dead cells from the surface of the skin revealing smoother, brighter skin. It can help to reduce hyperpigmentation. It has anti-bacterial properties, and might help to reduce blemishes, as well as fine lines and wrinkles. It is considered to be gentler than glycolic acid~1.4–2%
Alpha-arbutinKey activeEffect: HighMight help reduce hyperpigmentation when used regularly over a long period of time. Is more effective than beta-arbutin~1.2–1.9%
Glycyrrhiza glabra root extractEffect: LowA plant extract that can help lighten the skin and calm down inflammation. Might be helpful in neutralizing free radicals~4.4–6.7%
NiacinamideUnder-dosedIs 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~0.15–0.55%

What the product description says
“Rated 5.”
Source: N/A

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

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).

Hyaluronic acidKey activeEffect: 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~5.3–8%
Methyl gluceth-20Key activeEffect: MediumHelps attract water to the upper layer of the skin and soften it~3.1–4.7%
Beta-glucanKey activeEffect: HighHelps attract water to the upper layer of the skin, calm down inflammation and irritation, restore the barrier function and support wound healing. It can be helpful in reducing fine lines and wrinkles~2.5–3.7%
AllantoinKey activeEffect: HighHelps calm down inflammation in skin and can help reduce itching. Helps to repair the skin barrier and keep skin hydrated~1.7–2.6%
Sodium lactateKey activeEffect: HighHelps attract water to the upper layer of the skin. Is often used to adjust the pH level of the product~0.95–1.4%
Sodium pcaKey activeEffect: HighNaturally present in skin and helps to attract water to its upper layer~0.55–1.25%
GlycineKey activeEffect: HighHelps to attract water to the upper layer of the skin and can help restore the skin barrier function~0.35–0.8%
FructoseKey activeEffect: HighHelps attract water to the upper layer of the skin~0.2–0.75%
SucroseKey activeEffect: HighCan help attract water to the upper layer of the skin. In crystal form, it can work as a gentle exfoliant, gentler than the salt scrub. Helps stabilize the emulsion~0.1–0.35%
Glucose oxidaseKey activeEffect: HighHelps attract water to the upper layer of the skin~0.05–0.15%
GlucoseKey activeEffect: MediumHelps attract water to the upper layer of the skin. Could be helpful in restoring the skin barrier function~0.05–0.25%
LactoperoxidaseKey activeEffect: HighHelps attract water to the upper layer of the skin. In theory, could support healthy skin's microbiome, but evidence of effectiveness in skin is lacking~0.01–0.1%
NiacinamideUnder-dosedIs proven to be effective in reducing blemishes, evening out skin tone and helping to improve lines and wrinkles.

“00 This skin-perfecting system clears congested pores, improves uneven skin tone, and reduces the appearance of fine lines and blemishes.”
Source: N/A

This product does not contain ingredients that are able to reduce fine lines and wrinkles or help with skin elasticity, but it can improve the look of the skin temporarily through moisturization. Well-moisturized skin might also be able to repair the sun damage better.These ingredients - beta-glucan, hyaluronic acid - could be helpful for preventing or repairing signs of aging in theory, but there is no evidence that it actually works.
