What the product description says
“Hydrates and supports comfort for active-treated skin”
Source: N/A

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

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, 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~3.7–5.6%
PanthenolHero· HumectantEffect: HighHelps attract water to the upper layer of the skin and can help improve skin barrier function~0.1–0.45%
Potassium azeloyl diglycinateKey activeEffect: MediumA derivative of azelaic acid. It is obtained by reacting the chloride of azelaic acid with two molecules of glycine (an amino acid) and potassium hydroxide. It is less studied than azelaic acid, but the available research suggests that it also can be effective in reducing skin redness, hyperpigmentation and blemishes. There are claims that it is more bio-available and more effective than azelaic acid, but no comparison study is available. Potassium azeloyl diglycinate is better soluble in water compared with azelaic acid. Because of this property, products with potassium azeloyl digclycinate can have a nicer texture~2.1–3.1%
Tranexamic acidKey activeEffect: HighAn amino acid that is effective in reducing hyperpigmentation and evening out the skin tone. It can also help in skin barrier recovery. It is used to treat melasma, especially with injections and when taken orally~1.4–2.1%
Sodium pcaKey active· HumectantEffect: HighNaturally present in skin and helps to attract water to its upper layer~1.2–1.9%
Centella asiatica extractKey activeEffect: HighA plant extract that has been shown to be able to reduce inflammation in skin, support restoration of skin barrier function, as well as support collagen production. Contains active compounds called centelloids: asiaticoside, madecasosside, asiatic acid and madecassic acid. Might be helpful in preventing stretch marks. It can be itself be irritating though.~0.55–1.3%
BetaineKey active· HumectantEffect: HighHelps attract water to the upper layer of the skin and improves the product texture~0.5–1.2%
Zinc pcaKey active· HumectantEffect: HighA compound that combines zinc with a hydrating ingredient PCA. Might to be helpful against acne and clogged pores. Can help calm down inflammation in skin. Could be helpful in reducing the formation of free radicals in skin. Might help to reduce fine lines in wrinkles, but solid evidence is missing~0.4–0.95%
Sodium hyaluronateKey active· HumectantEffect: HighOne of the best moisturizing ingredients. Attracts water into the upper layer of the skin~0.1–0.35%
Saccharide isomerateKey active· HumectantEffect: HighHelps attract water to the upper layer of the skin~0.05–0.25%
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)~0.35–0.8%

What the product description says
“acne marks”

This product can help reduce breakouts and clogged pores because it contains the following ingredient: niacinamide, salicylic acid. These ingredients is used for treating acne and can have a noticeable effect.

In addition, this product contains potassium azeloyl diglycinate. It can help in reducing blemishes, even though it is less effective.

The following ingredient (ingredients) in this product might be helpful, but there is no evidence to confirm that it actually works: zinc pca

What the product description says
“Helps visibly improve the look of dark spots and post-breakout marks”
Source: N/A

This product can help reduce hypepigmentation and even out the skin tone because it contains the following effective ingredients: niacinamide, potassium azeloyl diglycinate, salicylic acid, tranexamic acid

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
Not advertised by the brand · Niacinamide, Centella asiatica extract + 2 more
Works well

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: centella asiatica extract.

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.

Exfoliation
Not advertised by the brand · Salicylic acid, Lactic acid
Works well

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: salicylic acid.

Salicylic acidKey activeEffect: HighUsed for skin exfoliation. It has an anti-inflammatory and anti-bacterial effect, helps to unclog pores, prevent blemishes and speed up healing of the existing ones. Sometimes referred to as a BHA (beta-hydroxy acid)~0.2–0.8%

This product contains antioxidants (centella asiatica extract) that might be able to help neutralize free radicals in skin to lessen the damage it gets from the UV light (sun). There is not enough evidence to confirm their effectiveness in skin though.
