Salicylic acidHeroEffect: 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)~1.25–2.5%

What the product description says
“The Sekkisei brightening skin care series uses a Japanese herbal extract that gently moisturizes and protects skin while brightening the complexion.”
Source: Yesstyle

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

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~0.4–0.9%
DiglycerinKey active· HumectantEffect: HighHelps attract water to the upper layer of the skin~0.1–0.4%
Dipotassium glycyrrhizateKey active· HumectantEffect: HighA salt derived from licorice. Works as an emollient to soften the upper layer of the skin and can help calm down inflammation. Might be helpful for skin lightening~4.1–6.1%
GlycerinKey active· HumectantEffect: HighOne of the best moisturizing ingredients. Naturally present in skin. It attracts water to the upper layer of the skin working as a humectant~0.95–1.45%
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~2.3–3.4%
AgarEffect: LowPolysaccharide derived from seaweed. Used to create a thicker product consistency and might help attract water to the upper layer of the skin~0.3–0.75%
Lactic acidUnder-dosedEffect: HighAn 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)~0.01–0.1%
Exfoliation
Not advertised by the brand · Salicylic acid, Lactic acid
Strong evidence

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)~1.25–2.5%

Anti-oxidation
Not advertised by the brand · Ascorbyl glucoside
Moderate evidence

This product contains antioxidants (ascorbyl glucoside) 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.

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%
Anti-aging
Not advertised by the brand · Ascorbyl glucoside, Hyaluronic acid + 1 more
Moderate evidence

This product contains ascorbyl glucoside. This ingredient might be able to help reduce and prevent fine lines and wrinkles, improve skin elasticity and firmness, but there is not enough evidence that it actually works.

Evens skin tone
Not advertised by the brand · Ascorbyl glucoside, Dipotassium glycyrrhizate + 2 more
Moderate evidence

This product might be able to help reduce hyperpigmentation and even out the skin tone because it contains salicylic acid. The effect, if any, is likely to be small. 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.

The following ingredient (ingredients) in this product might be helpful, but there is no evidence to confirm that it actually works: ascorbyl glucoside, dipotassium glycyrrhizate.
