What the product description says

“, Highly Stable Vitamin C (Tetrahexyldecyl Ascorbate) Supports collagen production and reduces the look of wrinkles.”

Source: Sephora CA

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. 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~1.3–1.9%

Aloe barbadensis leaf juiceEffect: LowTraditionally used to treat sunburns, dermatitis and inflammation, but evidence for its effectiveness is lacking. The extract can contain humectants that help attract water into the skin~23–34%

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.~0.9–1.4%

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)~0.5–1.1%

What the product description says

“Green Machine Vitamin C Dark Spot & Hyperpigmentation Serum”

From product name

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

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: pinus pinaster bark extract.

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.

Tranexamic acidKey activeEffect: HighAn amino acid that is effective in reducing hyperpigmentation and evening out the skin tone. It can also help in skin barrier recovery. It is used to treat melasma, especially with injections and when taken orally~2.1–3.2%

Kojic acidKey activeEffect: HighHelps to reduce hyperpigmentation and neutralize free radicals. Can be irritating~0.5–1.2%

Alpha-arbutinKey activeEffect: HighMight help reduce hyperpigmentation when used regularly over a long period of time. Is more effective than beta-arbutin~0.45–1.05%

Pinus pinaster bark extractEffect: LowA plant extract that might help neutralize free radicals and reduce hyperpigmentation, but evidence of effectiveness of topical application is lacking. It can be an INCI name for the trademarked ingredient Pycnogenol (but could also be a different type of this plant's bark extract)~0.15–0.6%

Potassium azeloyl diglycinateUnder-dosedA derivative of azelaic acid. It is obtained by reacting the chloride of azelaic acid with two molecules of glycine (an amino acid) and potassium hydroxide. It is less studied than azelaic acid, but the available research suggests that it also can be effective in reducing skin redness, hyperpigmentation and blemishes. There are claims that it is more bio-available and more effective than azelaic acid, but no comparison study is available. Potassium azeloyl diglycinate is better soluble in water compared with azelaic acid. Because of this property, products with potassium azeloyl digclycinate can have a nicer texture~0.35–0.8%

Anti-oxidation

Not advertised by the brand · Kojic acid, Pinus pinaster bark extract + 12 more

Works well

This product contains antioxidants (kojic acid) 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 - pinus pinaster bark extract also can have an antioxidant effect, but there is less evidence to confirm their effectiveness in skin.

Moisturizing

Not advertised by the brand · Isosorbide dicaprylate, Niacinamide + 19 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: glycerin, sodium hyaluronate.

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: chondrus crispus extract, helianthus annuus seed oil.

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

Isosorbide dicaprylateHero· EmollientEffect: HighHelps soften the upper layer of the skin. Early studies suggest that it can help strengthen the skin barrier~1.6–2.4%

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~4.5–6.7%

Helianthus annuus seed oilKey active· Emollient, OcclusiveEffect: HighA great emollient due to its high linoleic acid content. One of the most effective plant oils in helping skin hydration and repairing skin barrier function~3.4–5.1%

Cannabis sativa seed oilKey active· EmollientEffect: HighA plant oil that due to its high linoleic acid content can help strengthen skin's barrier function and soften its upper layer~1.2–1.8%

Ingredient callouts

This product contains acids (lactic acid 0.50% - 1.10%). 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.
Humectants (sodium hyaluronate 0.20% - 0.80% and glycerin 4.50% - 6.70%). These ingredients help attract water to the upper layer of the skin and improve the skin hydration.
