What the product description says
“Korean innovation with formulations designed to help reduce the appearance of blemishes.”
Source: Feelunique

This product might be able to help reduce blemishes and clogged pores because it contains 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~1.4–2.2%
Centella asiatica extractEffect: Low, below effective doseA 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.~0.2–0.75%
Camellia sinensis leaf extractEffect: Low, below effective doseCan contain potent anti-oxidant compounds (abbreviated ECG, GCG, EGC, and EGCG) that might help protect the skin from free radicals. Can help calm down inflammation and has some anti-bacterial properties. Unfortunately, these antioxidants are unstable and lose their effectiveness very quickly in products. The concentration of the antioxidant compounds in the extract also tends to be low to be effective in topical formulation~0.05–0.25%
Moisturizing

This product contains good ingredients to attract water to the upper layer of the skin. These ingredients are called "humectants": glycerin, bis-peg-18 methyl ether dimethyl silane.

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

It helps the skin to repair sun damage, calm down inflammation and keep maintain good levels of moisture.

GlycerinKey activeEffect: HighOne of the best moisturizing ingredients. Naturally present in skin. It attracts water to the upper layer of the skin working as a humectant~2.8–4.1%
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)~0.15–0.65%
Caprylyl glycolEffect: LowHelps preserve products and creates a nice product texture~0.85–1.25%
Bis-peg-18 methyl ether dimethyl silaneEffect: LowA type of silicone that helps soften the upper layer of the skin and create a nice product texture~3.8–5.7%
Butylene glycolEffect: 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~5.6–8.4%

Anti-aging
Not advertised by the brand · 4 ingredients credited for this claim
Strong support

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: adenosine.

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.

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.
