What the product description says
“This intensive brightening serum uses a carefully selected blend of 13 encapsulated actives to target dark spots, hyperpigmentation and uneven skin tone.”
Source: Face the Future

This product can help reduce hypepigmentation and even out the skin tone because it contains the following effective ingredients: glutathione, niacinamide

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: 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.

NiacinamideKey activeEffect: 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~5–6.1%
ArbutinKey activeEffect: MediumBeta-arbutin. Can help to reduce hyperpigmentation and has an anti-oxidant effect when used in high enough concentration. Is less effective compared to alpha-arbutin~2.3–2.9%
GlutathioneKey activeEffect: HighA peptide that can help neutralize free radicals in skin and reduce melanin production resulting in skin lightening effect and reduction in hyperpigmentation. It can also help attract moisture to the upper layer of the skin~2.1–2.5%

What the product description says
“This hydrating, easily absorbed serum contains 13 brightening actives to even out skin tone”
Source: Naturisimo

This product can help improve hydration of the skin with the two types of ingredients.

The first type is called “humectants”:
these ingredients help attract water. 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. The following ingredients in this product do the job: glycerin, saccharomyces/copper ferment.

This product also contains ingredients called “occlusives”. They help reduce the speed with which our skin loses moisture to the outside environment. These ingredients also help soften the upper layer of the skin, so it feels less tight and nicer to the touch. The following ingredients in this product do the job: jojoba esters.

The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: 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.

Works well
What the product description says
“Renaissance Brightlight works to diminish the visibility of discolorations and blemishes while leaving skin with a natural shine.”
Source: SpaceNK

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

In addition, this product contains sodium ascorbyl phosphate. It can help in reducing blemishes, even though it is less effective.

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~5–6.1%
Sodium ascorbyl phosphateKey activeEffect: HighA stable derivative of vitamin C. It is oil-soluble which means it is more likely to penetrate the skin compared to the pure form of vitamin C (which is water-soluble), but it is less bio-available and is way less effective in stimulating collagen and reducing wrinkles compared to the pure form of vitamin C (L-ascorbic acid) and its other derivatives (for example, magnesium ascorbyl phosphate). At the same time, this vitamin C derivative has been shown in studies to be effective in reducing acne, blemishes and clogged pores. It is less irritating then the pure form of vitamin C~7.3–8.9%
InulinEffect: LowHelps attract water to the upper layer of the skin. Is claimed to support the growth of "good" bacteria in skin (as a "prebiotic"), but the research is lacking~0.3–0.55%

What the product description says
“Boost skin’s natural radiance with Oskia Renaissance Brightlight, a daily serum that tackles dark spots, fine lines, wrinkles and sun damage.”
Source: SpaceNK

This product can help reduce and prevent fine lines and wrinkles, improve skin elasticity and firmness because it contains niacinamide.

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.

NiacinamideKey activeEffect: 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.

Ascorbyl palmitateEffect: Low, below effective doseBeing a lipid soluble form of vitamin C, it is more stable and can penetrate the skin better than L-Ascorbic acid. It is effective in protecting the skin from free radicals, as well as evening the skin tone, but is less effective in stimulating collagen production compared to L-Ascorbic acid.~1.3–1.6%
Exfoliation
No ingredient credited for this claim
Not delivered
What the product description says
“Fruit enzymes and AHAs work together to gently exfoliate, regenerate and illuminate the skin, while the unique OSKIA polypeptide complex boosts overall skin health to reveal a radiant and glowing complexion.”
Source: Face the Future

This product does not contain effective exfoliating ingredients. It might be able to deliver physical exfoliation, that is scrub off some of the dead cells on the surface of the skin. We do not recommend physical exfoliation, because it is not uniform (some bits of skin can get exfoliated too much while others not at all). It can also traumatize the skin and aggrevate acne and other skin conditions.

Anti-oxidation
Not advertised by the brand · Sodium ascorbyl phosphate, Arbutin + 5 more
Works well

This product contains antioxidants (glutathione) that can help neutralize free radicals in skin. By doing so, they can lessen the damage the skin gets from the UV light (sun).

The following ingredients - arbutin, sodium ascorbyl phosphate also can have an antioxidant effect, but there is less evidence to confirm their effectiveness in skin.

Sodium ascorbyl phosphateKey activeEffect: MediumA stable derivative of vitamin C.
