What the product description says
“Kose White Moisture Mild Repair Essence C100 20ml is a Japanese skincare product designed to deliver intense hydration and repair for a radiant complexion.”
Source: Buy Me Japan

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

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: panthenol

PanthenolHero· HumectantEffect: HighHelps attract water to the upper layer of the skin and can help improve skin barrier function~2–3%
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~7.3–10.9%
DiglycerinKey active· HumectantEffect: HighHelps attract water to the upper layer of the skin~2.6–3.9%
Sodium hyaluronateKey active· HumectantEffect: HighOne of the best moisturizing ingredients. Attracts water into the upper layer of the skin~1.8–2.7%
Royal jelly extractKey active· HumectantEffect: MediumA compound secreted by bees. Might be able to attract water to the top layer of the skin. Avoid if sensitive to honey and bee products~1.5–2.3%
Soluble collagenKey active· HumectantEffect: HighA typically plant-derived compound that is supposed mimic human collagen. Cannot penetrate the skin barrier so is not particularly useful in skincare products beyond attracting water to the upper layer of the skin~1.3–2%
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~3.2–4.8%

What the product description says
“The presence of Vitamin C and Niacinamide helps to lighten dark spots and even out skin tone, promoting a brighter and more luminous complexion.”
Source: Buy Me Japan

This product can help reduce hypepigmentation and even out the skin tone because it contains the following effective ingredients: tranexamic 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: ascorbyl glucoside.

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.

Ascorbyl glucosideKey activeEffect: MediumA vitamin C derivative that is more stable but less potent than pure form of vitamin C. Has a potential to boost collagen production, nutralise free radicals and reduce hyperpigmentation, but the required concentration is likely to be much higher than for the pure form of vitamin C, limiting the ingredient's effectiveness in products~23–34%
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~7.3–10.9%
Anti-oxidation
Side benefit · Ascorbyl glucoside
May help

This product contains antioxidants (ascorbyl glucoside) that can help neutralize free radicals in skin to lessen the damage it gets from the UV light (sun). There is some human evidence for this effect in skin, though it is smaller or less consistent than the evidence for the best antioxidants.

Anti-aging
Side benefit · Ascorbyl glucoside

This product contains ascorbyl glucoside. There is some human evidence that this ingredient helps reduce and prevent fine lines and wrinkles and improve skin elasticity and firmness, though it is smaller or less consistent than the evidence for the best anti-aging ingredients.
