What the product description says

“Bright & Correct Niacinamide Serum”

Source: Rejuvaus

This product can help reduce hypepigmentation and even out the skin tone because it contains the following effective ingredients: 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: dimethylmethoxy chromanyl palmitate.

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~4.1–6.1%

Dimethylmethoxy chromanyl palmitateKey activeEffect: MediumAn oil-soluble compound that has been shown in laboratory studies (in a petri dish, not on human volunteers) to inhibit melanin production in skin and help even out the skin tone. More research is needed to understand if it works in real life~0.35–0.8%

Phyllanthus emblica fruit extractEffect: Low, below effective doseA plant extract that might be helpful in neutralizing free radicals and have a skin lightening effect if used in high enough concentrations~0.35–0.8%

Galactomyces ferment filtrateUnder-dosedA yeast ferment filtrate (also known as Pitera - a trademarked name for the filtrate reserved by the SK-II brand). It helps attract water to the upper layer of the skin, can help neutralize antioxidants and can be helpful in evening out the skin tone. It might be somewhat helpful in preventing premature skin aging but solid evidence is lacking. A small manufacturer study also shows that, when used in high concentrations, it can help reduce sebum production and help against blocked pores~0.6–1.4%

Lactic acidUnder-dosedAn 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)~0.35–0.85%

Anti-aging

Niacinamide, Nonapeptide-1 + 8 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: nonapeptide-1, oligopeptide-68.

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.

Nonapeptide-1Key activeEffect: MediumA type of peptide. Peptides are excellent moisturizers and might be able support collagen production reducing fine lines and wrinkles~1.1–1.6%

Moisturizing

Side benefit · Niacinamide, Nonapeptide-1 + 26 more

Works well

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: dextran, glycerin.

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: squalane, glycine soja oil.

The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: niacinamide, nonapeptide-1, oligopeptide-68

NiacinamideHeroEffect: HighIs proven to be effective in reducing blemishes, evening out skin tone and helping to improve lines and wrinkles.

Product summary

"Rejuvaus - Bright & Correct Niacinamide Serum" is effective for: Evens skin tone, Anti-blemish, Anti-aging and Moisturizing

Ingredient callouts

A good concentration of Niacinamide (4.10% - 6.10%). 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.
Peptides (oligopeptide-68 0.45% - 1.00% and nonapeptide-1 1.10% - 1.60%). There are many different kind of Peptides and they are naturally present in our skin. They all are a combination of aminoacids. Some of them work as natural antibiotics, promote wound-healing and production of collagen. The science is still not settled on how effective Peptides are in skincare, but it is very likely that they have a benefit. They might help restore the skin barrier and fight the signs of aging. At the very least, Peptides work as humectants: they attract water to the upper layer of the skin and improve its hydration.
Humectants (hydrolyzed hyaluronic acid 0.35% - 0.80%, sodium hyaluronate 0.35% - 0.80%, sucrose 0.30% - 0.75%, dextran 1.20% - 1.80% and glycerin 4.40% - 6.60%). These ingredients help attract water to the upper layer of the skin and improve the skin hydration.
