Anti-aging
Tetrahexyldecyl ascorbate, Camellia sinensis leaf extract
Strong evidence
What the product description says
“This innovative, scientific concentrate is enriched with vitamin C boosters to give you a more radiant and youthful complexion.”
Source: Feelunique

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

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.

Tetrahexyldecyl ascorbateKey activeEffect: HighBeing 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.~8.1–12.2%
Camellia sinensis leaf extractEffect: LowCan contain potent anti-oxidant compounds (abbreviated ECG, GCG, EGC, and EGCG) that might help protect the skin from free radicals. Can help calm down inflammation and has some anti-bacterial properties. Unfortunately, these antioxidants are unstable and lose their effectiveness very quickly in products. The concentration of the antioxidant compounds in the extract also tends to be low to be effective in topical formulation~0.5–1.2%

Vitis vinifera seed oil, Caprylic/capric triglyceride + 9 more
Good evidence
What the product description says
“replenish skin's surface layer with essential fatty acids and restore its natural moisture barrier to aid against water loss and environmental damage .”
Source: Feelunique

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, caprylyl glycol.

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: caprylic/capric triglyceride, helianthus annuus seed oil.

Vitis vinifera seed oilKey activeEffect: HighA great emollient that can also have anti-oxidant properties~0.2–0.8%
Caprylic/capric triglycerideKey activeEffect: HighA good mix of fatty acids that forms a protective layer on the skin. Improves the shelf life of products. Derived from coconut and glycerin~23–34%
Helianthus annuus seed oilKey activeEffect: 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~4.8–7.2%
Oryza sativa bran oilKey activeEffect: HighHelps soften the upper layer of the skin and might have some anti-oxidant properties~0.15–0.6%
Passiflora edulis seed oilKey activeEffect: HighA good emollient helping to soften the skin. Might have some anti-oxidant properties. Adds a fragrance to the product~0.35–0.8%
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~0.45–1.05%
GlycerinKey activeEffect: HighOne of the best moisturizing ingredients. Naturally present in skin. It attracts water to the upper layer of the skin working as a humectant~0.1–0.35%
Caprylyl glycolEffect: LowHelps preserve products and creates a nice product texture~3.6–5.5%
Passiflora incarnata seed oilEffect: LowA plant oil that can help soften the upper layer of the skin. Contains essential oil that can be irritating~1–1.6%
Camellia sinensis leaf extractEffect: LowCan contain potent anti-oxidant compounds (abbreviated ECG, GCG, EGC, and EGCG) that might help protect the skin from free radicals. Can help calm down inflammation and has some anti-bacterial properties. Unfortunately, these antioxidants are unstable and lose their effectiveness very quickly in products.

Sclerocarya birrea seed oilUnder-dosedEffect: MediumAn emollient that helps to soften the skin. It has a high contetn of oleic acid that might weaken the skin barrier. Might have some anti-oxidant properties. It might be somewhat helpful against hyperpigmentation.~0.45–1.1%
Anti-oxidation
Not advertised by the brand · Tetrahexyldecyl ascorbate, Superoxide dismutase + 8 more

Evens skin tone
Not advertised by the brand · Tetrahexyldecyl ascorbate, Emblica officinalis fruit extract + 1 more
Strong evidence

This product can help reduce hypepigmentation and even out the skin tone because it contains the following effective ingredients: tetrahexyldecyl ascorbate

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: emblica officinalis fruit 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.
