Glycyrrhiza glabra root extract, Tetrahydrobisdemethoxydiferuloylmethane + 4 more
Limited evidence
What the product description says
“All Priori TTC products feature an exclusive, highly potent natural compound of 3 kinds of colorless turmeric root PLUS green tea, grape seed and licorice for a powerful multifunctional adaptive action: antioxidant, brightening and anti-inflammatory.”
Source: Skinstore

This product contains ingredients (glycyrrhiza glabra root extract, tetrahydrobisdemethoxydiferuloylmethane, tetrahydrodemethoxydiferuloylmethane, tetrahydrodiferuloylmethane) that could help reduce hyperpigmentation (for example, post-acne marks or age spots) in theory, but there is not enough evidence that they actually work.

Glycyrrhiza glabra root extractEffect: LowA plant extract that can help lighten the skin and calm down inflammation. Might be helpful in neutralizing free radicals~0.1–0.35%
TetrahydrobisdemethoxydiferuloylmethaneEffect: LowAn anti-oxidant derived from curcumin (naturally present in tumeric). It might be helpful in neutralizing free radicals in skin and possibly help even out the skin tone. Can be irritating~0.15–0.7%
TetrahydrodemethoxydiferuloylmethaneEffect: LowAn anti-oxidant derived from curcumin (naturally present in tumeric). Is a part of the tetrahydrocurcuminoids complex (THC). The complex might be helpful in neutralizing free radicals in skin and possibly help even out the skin tone. Can be irritating~0.3–0.7%
TetrahydrodiferuloylmethaneEffect: LowAn anti-oxidant derived from curcumin (naturally present in tumeric). Is a part of the tetrahydrocurcuminoids complex (THC). The complex might be helpful in neutralizing free radicals in skin and possibly help even out the skin tone. Can be irritating~0.35–0.85%
Lactic acidUnder-dosedEffect: HighAn 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)~0.05–0.15%
Camellia sinensis leaf extractEffect: Low, below effective doseCan 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~0.1–0.45%

The following ingredients - tetrahydrobisdemethoxydiferuloylmethane, tetrahydrodemethoxydiferuloylmethane, tetrahydrodiferuloylmethane also can have an antioxidant effect, but there is less evidence to confirm their effectiveness in skin.
