1-TRIMETHYL-2-CYCLOHEXENYL-1-PENTEN-3-ONE ASCORBYL TETRAISOPALMITATEA vitamin C derivative. Studies show that is might be effective in reducing hyperpigmentation, but there are no studies confirming that it is effectively converted into the bioavailable form of Vitamin C in skin. It is not clear how this derivative compares in effectiveness to the topical application of bioavailable form of vitamin C (L-ascorbic acid) ASCORBYL GLUCOSIDEA vitamin C derivative that is more stable but less potent than pure form of vitamin C. Has a potential to boost collagen production, nutralise free radicals and 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 ACETYL GLUCOSAMINEAn effective moisturizing ingredient that also has been shown to be effective in evening out the skin tone and reducing hyperpigmentation. It can help somewhat reduce wrinkles in skin GLUCOSAMINE HCLMight be able to stimulate production of skin's natural moisturizing compounds such as hyaluronic acid. Could be helpful for evening the skin tone.GLYCINE SOJA SEED EXTRACTAn emollient that helps soften the skin. Might be somewhat helpful in evening the skin tone.GLYCOLIC ACIDAn alpha-hydroxy acid (AHA) that helps to remove the dead skin cells on the surface of the skin reveling a more even, smoother complexation. It is also able to stimulate collagen production with long-term use. Could help to reduce pore congestion. It can be irritating to the skin. Apply sunscreen daily if using products with glycolic acid GLYCYRRHIZA GLABRA ROOT EXTRACTA plant extract that can help lighten the skin and calm down inflammation. Might be helpful in neutralizing free radicals LACTIC ACIDAn 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 microbiom) NIACINAMIDEIs 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 PALMITOYL GRAPEVINE SHOOT EXTRACTAn extract from grape plant that can contain a potent antioxidant resveratrol. 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 activity MAGNESIUM 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 be helpful in stimulating collagen production and lightening the skin tone, but the required concentration is likely to be very high STEARYL GLYCYRRHETINATEA fatty acid derived from licorice. Works as an emollient and can help calm down inflammation DIPOTASSIUM GLYCYRRHIZATEA salt derived from licorice. Works as an emollient to soften the upper layer of the skin and can help calm down inflammation. Might be helpful for skin lightening GLYCYRRHETINIC ACIDActive compound of licorice root. Works to calm down inflammation, as an anti-oxidant, and might be helpful in lightening the skin and reducing hyperpigmentation AMINOPROPYL ASCORBYL PHOSPHATEA more stable but less potent derivative of vitamin C. 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 effect HYDROXYPINACOLONE 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.

It can help calm down inflammation in skin MORUS NIGRA ROOT EXTRACTA plant extract that might help neutralize free radicals in skin and have some skin-lightening effect, but good evidence is missing LACTOBIONIC ACIDA polyhydroxy acid (PHA) that helps shed dead cells from the surface of the skin revealing a smoother, more even skin. PHAs tend to be gentler on the skin compared to AHAs (for example, glycolic acid). It also has hydrating properties and helps attract water to the upper layer of the skin. It can help calm down inflammation in skin and support restoration of the barrier function. It has an anti-oxidant effect as well. It can help reduce fine line, wrinkles and improve skin elasticity TETRAHEXYLDECYL ASCORBATEBeing a lipid soluble form of vitamin C, it is more stable. 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. ALANINEAn amino-acid that helps to attract water to the upper layer of the skin and might help to lighten the skin, but solid evidence is lacking GLUCONOLACTONEA polyhydroxy acid (PHA) that helps shed the dead cells from the skin surface revealing smoother 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 GLUCONIC ACIDA polyhydroxy acid (PHA) that helps shed the dead cells from the skin surface revealing smoother skin. Is believed to be genter than AHAs. It helps attract water to the upper layer of the skin and can stimulate production of skin's own hyaluronic acid resulting in imporved hydration levels. It has been shown to be helpful against acne and clogged pores. Might help reduce fine lines and wrinkles and improve skin tone with long-term application. Can help neutralize free radicals CERATONIA SILIQUA FRUIT EXTRACTPlant extract that might help neutralize free radicals in skin and even out skin tone, but evidence of effectiveness in skin is lacking GALACTOMYCES FERMENT FILTRATEA yeast ferment filtrate (also known as Pitera - a trademarked name for the filtrate reserved by the SK-II brand). It helps attract water to the upper layer of the skin, can help neutralize antioxidants and can be helpful in evening out the skin tone. It might be somewhat helpful in preventing premature skin aging but solid evidence is lacking. A small manufacturer study also shows that, when used in high concentrations, it can help reduce sebum production and help against blocked pores MORUS ALBA BARK EXTRACTA plant extract that might have anti-oxidant properties and help even out skin tone, but solid evidence is lacking LACTOBACILLUS/PORTULACA OLERACEA FERMENT EXTRACTObtained from fermenting a plant extract with bacteria Lactobacillus. The resulting compound might be able to calm down inflammation and have some anti-oxidant properties, but solid evidence is missing RETINYL PROPIONATEThree 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, even thought its potency is not as well established as in case of retinol or retinaldehyde 3-GLYCERYL ASCORBATEA moisturizing vitamin C derivative. It is considered to be one of the most stable ones. It is effective in neutralizing free radicals and can help to even out the skin tone if used in high enough concentration 3-O-ETHYL ASCORBIC ACIDA 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 UNDECYLENOYL PHENYLALANINEAn amino-acid based compound that is effective in reducing hyperpigmentation. It can help lighten sun spots and support more even skin tone. PRUNUS MUME FRUIT EXTRACTA plant extract that might have an anti-oxidant effect and help even out skin tone, but solid evidence of effectiveness is lacking MADECASSOSIDEAn antioxidant that is typically derived from plant Centella Asiatica. It can help neutralize free radicals in skin and support skin barrier function. It could, however, itself be irritating. It is often unstable in formulations NIACINA form of vitamin B3. It is similar in action to niacinamide, but is more likely to cause red flashes in skin as the side effect BAKUCHIOLA plant extract that is, though different in chemical structure, acts similar to retinoids. First studies show that it can help reduce fine lines and wrinkles, improve skin tone, reduce clogged pores and blemishes, and reduce inflammation. 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 irritation ADAPALENEA retinoid that is effective against acne and keratosis pilaris. It can also help reduce signs of aging (fine lines, wrinkles, loss of elasticity) and can improve skin tone AZELAIC ACIDIs produced by a yeast that lives on normal human skin. It is used in medicine as a topical treatment for mild to moderate acne. It has a mild exfoliating effect. It can also help reduce hyperpigmentation, helps calm down inflammation and can help neutralize free radicals TRANEXAMIC ACIDAn amino acid that is effective in reducing hyperpigmentation and evening out the skin tone HEXYLRESORCINOLMight be helpful in reducing hyperpigmentation and neutralizing free radicals in skin PHENYLETHYL RESORCINOLMight help reduce hyperpigmentation in skin and help neutralize free radicals CAPRYLOYL SALICYLIC ACID KOJIC ACIDHelps to reduce hyperpigmentation and neutralize free radicals. Can be irritating RETINYL LINOLEATEAn ester of a retinoid and linoleic acid. Three steps removed from the bioactive form of retinoid, retinoic acid. Once converted to retinoic acid in skin, it can help reduce wrinkles, stimulate collagen production, even out skin tone and reduce blemishes. The concentrations used in cosmetic products are often not high enough to have a positive effect in skin. NARCISSUS TAZETTA BULB EXTRACTMight contain compounds called dormins that in theory could help lighten skin and reduce hyperpigmentation, but solid research is lacking GLYCYRRHIZA INFLATA ROOT EXTRACTA plant extract that can help lighten the skin and calm down inflammation. Might be helpful in neutralizing free radicals BIFIDA FERMENT LYSATEConsists of remains of dead yeast bacteria cells. Helps to hydrate the skin and reduce irritation. Might has some anti-oxidant effect ALPHA-ARBUTINMight help reduce hyperpigmentation when used regularly over a long period of time.

Is claimed to help reduce hyperpigmentation but evidence is missing ALBIZIA JULIBRISSIN SEED EXTRACTA plant extract that might help to neutralize free radicals in skin. Is claimed to help reduce hyperpigmentation but evidence is missing PANCRATIUM MARITIMUM EXTRACTA plant extract that might help neutralize free radicals in skin. It might help reduce hyperpigmentation EMBLICA 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 skin PAEONIA LACTIFLORA ROOT EXTRACTA plant extract that might help neutralize free radicals and reduce hyperpigmentation, but the research on its effectiveness in skin is lacking POTASSIUM 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 texture GLUTATHIONEA 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 skin ISOQUERCITRINAntioxidant that might help reduce free radicals and reduce melanin production, but more research is needed to understand if it is effective in skin CYSTEINEMight help neutralize free radicals in skin and might be helpful against hyperpigmentation DIMETHYLMETHOXY 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 life TretinoinBioavailable 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 UK POTASSIUM METHOXYSALICYLATECan help reduce hyperpigmentation EPIGALLOCATECHIN 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 skincare ARBUTINBeta-arbutin. Can help to reduce hyperpigmentation and has an anti-oxidant effect when used in high enough concentration. Is less effective compared to alpha-arbutin RETINYL 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 retinol RETINALOne 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 irritating RETINOLTwo 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 irritating ASCORBIC 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 aging ISOBUTYLAMIDO 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 effects HYDROQUINONE COPPER 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. It can help attract water to the upper layer of the skin. Might to be helpful against acne and clogged pores. Could be helpful in neutralizing free radicals, but solid research is missing RESVERATROL DIMETHYL ETHERA more stable derivative of anti-oxidant resveratrol. There is not enough research to confirm its efficacy in skin
