What the product description says
“Alpha Arbutin is a naturally occurring antioxidant and it reduces melanin formation, improving the appearance of age spots, melasma, and post-inflammatory pigmentation.”

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

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.

Alpha-arbutinKey activeEffect: HighMight help reduce hyperpigmentation when used regularly over a long period of time. Is more effective than beta-arbutin~6.6–10%

What the product description says
“5% Alpha Arbutin + 1%Hyaluronic Acid + 0.”
From product name

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

Hyaluronic acidKey active· HumectantEffect: 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~2–3.1%
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~1.2–1.8%
