What the product description says

“Visibly transform the skin’s appearance with Dr. Dennis Gross Skincare Vitamin C + Lactic 15% Vitamin C Firm & Bright Serum, a facial serum that works to correct the look of uneven tone and minimise the appearance of fine lines and wrinkles.”

Source: SpaceNK

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: lactic acid.

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. 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~3.1–3.7%

Lactic acidKey activeEffect: MediumAn 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)~1.9–2.3%

3-o-ethyl ascorbic acidEffect: LowA vitamin C derivative that is more stable but less potent than pure form of vitamin C. Can help neutralize free radicals and help 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~4.3–5.2%

UbiquinoneEffect: LowCoenzyme Q10. It helps neutralize free radicals in skin, improves skin hydration and might be helpful agains fine lines and wrinkles. It can be an allergen~0.45–0.65%

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~0.9–1.15%

Tetrahexyldecyl ascorbateUnder-dosedBeing a lipid soluble form of vitamin C, it is more stable than ascorbic acid, but still degrades quickly and needs to be stabilized in a formulation with another ingredient. It is claimed to penetrate skin better than pure vitamin C and have the the similar benefits, but solid studies of its effectiveness are lacking. Is likely to require a higher concentration in a product than pure vitamin C to be effective. It might be able to help reduce pore clogging.~0.3–0.6%

Evens skin tone

“Visibly transform the skin’s appearance with Dr. Dennis Gross Skincare Vitamin C + Lactic 15% Vitamin C Firm & Bright Serum, a facial serum that works to correct the look of uneven tone and minimise the appearance of fine lines and wrinkles.”

Source: SpaceNK

This product can help reduce hypepigmentation and even out the skin tone because it contains the following effective ingredients: lactic acid, mandelic acid, 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: 3-o-ethyl ascorbic acid, emblica officinalis fruit extract, hexylresorcinol.

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.

Recent studies show that lactic acid can support the "good" bacteria living on skin's surface (healthy skin microbiome)~1.9–2.3%

Mandelic acidKey activeEffect: HighHelps shed the upper layer of dead cells from the surface of the skin revealing smoother, brighter skin. It can help to reduce hyperpigmentation. It has anti-bacterial properties, and might help to reduce blemishes, as well as fine lines and wrinkles. It is considered to be gentler than glycolic acid~0.25–0.5%

HexylresorcinolEffect: LowMight be helpful in reducing hyperpigmentation and neutralizing free radicals in skin~0.45–0.65%

Emblica officinalis fruit extractEffect: LowA plant extract that might be helping in neutralizing free radicals in skin. It could help reduce hyperpigmentation. There is some research to confirm its effectiveness in skin~0.35–0.65%

Hydrolyzed soy proteinEffect: LowHelps attract water to the upper layer of the skin. Might have some anti-aging, anti-oxidant, and skin lightening properties, but solid evidence is missing~0.35–0.6%

Moisturizing

Niacinamide, Glycerin + 8 more

Works well

What the product description says

“It also contains mulberry and liquorice extracts to promote firmer skin and a stronger moisture barrier while also working to fade the look of dark spots.”

Source: SpaceNK

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

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

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.

Collagen amino acidsKey activeEffect: HighHelp attract water to the upper layer of the skin, soften it and support the skin barrier function~0.65–1%

Superoxide dismutaseKey activeEffect: HighAn antioxidant enzyme that is naturally present in skin. It can help support skin barrier function and reduce inflammation in skin. It is used in topical medications for inflammatory skin conditions including atopic dermatitis (eczema) and psoriasis. There are three types of natural Superoxide Dismutase in human skin. The compound used in topical treatments and cosmetics are mimics of typically one of these natural variants~0.55–0.8%

GlycineKey active· HumectantEffect: HighHelps to attract water to the upper layer of the skin and can help restore the skin barrier function~0.5–0.75%

Anti-oxidation

Side benefit · 3-o-ethyl ascorbic acid, Superoxide dismutase + 6 more

Works well

Exfoliation

Side benefit · Lactic acid, Mandelic acid

Works well

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: lactic acid, mandelic acid.

Product summary

"Dr Dennis Gross - C + Collagen™ Brightening Vitamin C Serum | Dr. Dennis Gross" is effective for: Anti-aging, Exfoliation, Moisturizing, Anti-blemish and Evens skin tone

Ingredient callouts

A good concentration of Niacinamide (3.10% - 3.70%). 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 contains acids (mandelic acid 0.25% - 0.50% and lactic acid 1.90% - 2.30%). Their concentration is low, and they will not have a strong exfoliating effect. Instead, they work to support the skin natural acid mantle and to attract water (as humectants). Lactic acid is particularly good in attracting water to the upper layer of the skin and improving the skin barrier.
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 (0.90% - 1.15%) it cannot have a noticeable benefit for the skin.
Humectants (glycine 0.50% - 0.75% and glycerin 4.50% - 5.60%). These ingredients help attract water to the upper layer of the skin and improve the skin hydration.
