The manufacturer (Caudalie) claims that this particular extract is effective against hyperpigmentation. This effect would be explained by the resveratrol content. However, there is no independent research confirming the manufacturer's claim beside the potential for anti-oxidant activityMAGNESIUM ASCORBYL PHOSPHATEA derivative of vitamin C that is more stable, but less bioavailable than the pure form of vitamin C. It does not penetrate the skin well, but has been shown to convert to pure vitamin C once in skin.

It can help neautralize free radicals and even out the skin tone if used in high enough concentration (required levels are likely to be much higher than for pure vitamin C, and solid studies are lacking at the moment)RETINYL PALMITATEThree steps removed from the active form of vitamin A - retinoic acid. To have an effect in the skin, it first needs to be converted twice to become the retinoic acid. This means it is less potent than retinol, but could also be less irritating. Once converted to the retinoic acid in the skin, it helps against all signs of aging, improves skin cell turnover and helps fight blemishes and clogged pores. However, in many cosmetic formulations, it is used in a concentration that is too low to have the full effectHYDROXYPINACOLONE RETINOATEA derivative of the most potent form of vitamin A, retinoic acid. The ingredient can be sold under name Granactive Retinoid. Note that if a skincare brand discloses the concentration of Granactive Retinoid in a product, the concentration refers to a diluted form of Hydroxypinacolone Retinoate: 1% of Granactive Retinoid corresponds to 0.1% of Hydroxypinacolone Retinoate. Hydroxypinacolone Retinoate (HPR) is a unique derivative of retinoic acid because it can directly work in the skin and does not require additional conversion steps. According to studies done by the manufacturer on models of human skin (not real people), this derivative is more effective than other cosmetic versions of retinoids (such as retinol, retinaldehyde, and retinyl palmitate), and, at the same time, causes less irritation. It has been also demonstrated to be more stable than retinol which makes formulating with easier and increases the chances that a product with it will maintain its effectiveness after opening. The packaging should still ideally be air-tight. HPR is available over the counter in the EU, UK, Asia, Australia and New Zealand, but is only with a prescription in Canada.MORUS BOMBYCIS ROOT EXTRACTA plant extract that might contain arbutin, a compound that has skin-lightening properties.

There is no conclusive evidence that bakuchiol is as effective as retinol however. The study that directly compared retinol with bakuchiol used bakuchiol applied twice daily compared to once per day for the retinol. According to this study, bakuchiol is less irritating than retinol. Bakuchiol is extracted from seeds of Babchi plant. Other parts of the plant contain coumarins that could cause allergic and irritant reactions. These compounds should be removed in the extraction process when bakuchiol is produced, but it is a good idea to be cautious and stay away from products that include the Babchi plant extracts other than purified bakuchiol to avoid irritationADAPALENEA retinoid that is effective against acne and keratosis pilaris.

It might help reduce hyperpigmentationEMBLICA OFFICINALIS FRUIT EXTRACTA 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 skinPOTASSIUM AZELOYL DIGLYCINATEA 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 textureGLUTATHIONEA peptide that can help neutralize free radicals in skin and reduce melanin production resulting in skin lightening effect and reduction in hyperpigmentation. It can also help attract moisture to the upper layer of the skinISOQUERCITRINAntioxidant that might help reduce free radicals and reduce melanin production, but more research is needed to understand if it is effective in skinCYSTEINEMight help neutralize free radicals in skin and might be helpful against hyperpigmentationDIMETHYLMETHOXY CHROMANYL PALMITATEAn 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 lifeTretinoinBioavailable form of Vitamin A that is the most effective known topical ingredients for reducing wrinkles, improving skin firmness, treating acne, as well as hyperpigmentation. It is not available over-the counter in many countries, including US and UKPOTASSIUM METHOXYSALICYLATECan help reduce hyperpigmentationEPIGALLOCATECHIN GALLATEA polyphenol found in tea. This particular compound abbreviated EGCG is the most powerful antioxidant among those extracted from tea (usually green tea). Unfortunately, EGCG is unstable, requires a low pH (below 4) to prevent quick degradation, and does not penetrate the skin very well. This is why the full anti-oxidant effect of EGCG is typically not realized when it is added to topical skincareARBUTINBeta-arbutin. Can help to reduce hyperpigmentation and has an anti-oxidant effect when used in high enough concentration. Is less effective compared to alpha-arbutinRETINYL RETINOATEA "hybrid" of retinol and retinoic acid. It is more stable than retinol and is likely to be more effective based on the early research data available. Is as irritating as retinolRETINALOne step removed from the biologically active in skin form of vitamin A. Once converted to the retinoic acid in the skin, retinal is proven to be effective against all signs of aging. It improves skin cell turnover, helps fight blemishes and clogged pores, can regulate excess oil production and even skin tone. Concentrations of 0.05% and 0.1% are shown to be effective. It can, however, be irritatingRETINOLTwo steps removed from the active form of vitamin A - retinoic acid. Once converted to the retinoic acid in the skin, retinol is proven to be effective against all signs of aging. It improves skin cell turnover, helps fight blemishes and clogged pores, can regulate excess oil production and even skin tone. It can, however, be quite irritatingASCORBIC ACIDThe 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 agingISOBUTYLAMIDO THIAZOLYL RESORCINOLSometimes referred to as Thiamidol (patented by Beiersdorf). A compound that can reduce melanin production in skin. Can help to fade pigmentation spots quicker and even out the skin tone. It is a relatively new compound and the research on it is ongoing. The first studies show that it might be as effective in reducing hyperpigmentation as hydroquinone but with fewer side effectsHYDROQUINONECOPPER GLUCONATETypically used to stabilize the product formulations. It is a salt of polyhydroxy acid (PHA) and in larger concentrations, can help shed the dead cells from the skin surface revealing smoother skin.
