What the product description says

“79.9% Fresh Jeju Lemon + Vitamin CA serum formulated with fresh Jeju Lemon [Citrus Limon (Lemon) Fruit Extract] and Niacinamide to moisturize skin and care for brighter looking skin.”

Source: iHerb

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

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

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 production4%

It can be itself be irritating though.~2.1–3.2%

Corallina officinalis extractKey activeEffect: HighRed algae extract that helps attract water to the upper layer of the skin and might contain antioxidants~1–1.5%

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~0.1–0.5%

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

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 production4%

Ascorbic acidUnder-dosedThe most well-researched antioxidant that works in skin. Helps neutralize free radicals supporting collagen production, helping to even out the skin tone and preventing early signs of aging~0.15–0.65%

Ascorbyl glucosideUnder-dosedA 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~0.15–0.55%

Anti-aging

Side benefit · Niacinamide, Centella asiatica extract + 3 more

Works well

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: centella asiatica extract.

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.

Product summary

"NATURE REPUBLIC - Vitapair C, Dark Spot Serum" is effective for: Moisturizing, Evens skin tone, Anti-blemish and Anti-aging

Ingredient callouts

A good concentration of Niacinamide (4.00% (declared)). Niacinamide is a well-studied multi-tasking active. It is stable, and can work well in almost any hydrating formulation. There is solid evidence that Niacinamide can help support skin barrier, regulate oil production and reduce acne and clogged pores. It also helps to fight photodamage and improve the skin tone, reducing pigmentation marks.
This product also contains Vitamin C (Ascorbic Acid). It can be an effective active for anti-aging and evening out the skin tone, but in this product it is used for stabilizing other ingredients in the formulation. In this concentration (0.20% - 0.75%) it cannot have a noticeable benefit for the skin.
An effective concentration of Panthenol (pro-vitamin B5) - about 0.40% - 0.95%. Panthenol helps strengthen the skin barrier, improve hydration and reduce inflammation in skin.
Humectants (panthenol 0.40% - 0.95%). These ingredients help attract water to the upper layer of the skin and improve the skin hydration.
