It can be irritating to sensitive skin. Might be helpful in preventing stretch marks. It could, however, itself be irritating.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 irritationCENTELLA ASIATICA LEAF CELL EXTRACTA plant extract that has been shown to be able to reduce inflammation in skin, support restoration of skin barrier function, as well as support collagen production.

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 textureSUPEROXIDE DISMUTASEAn 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.

Exfoliation
1-TRIMETHYL-2-CYCLOHEXENYL-1-PENTEN-3-ONEGLYCOLIC 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 acidLACTIC 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 microbiome) 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 irritatingLACTOBIONIC 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 GLUCONOLACTONEA 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 improved hydration levels. It has been shown to be helpful against acne and clogged pores if used consistently (e.g over a period of 12 weeks) in high enough concentration. It can help reduce fine lines and wrinkles and improve skin tone with long-term application.

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 radicalsRETINYL 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 retinaldehydeCAPRYLOYL SALICYLIC ACIDHYDROXYETHYL UREAA derivative of urea, a compound that is naturally present in skin. Attracts water to the upper layer of the skin. Can enhance penetration of other ingredientsRETINYL RETINOATEA "hybrid" of retinol and retinoic acid.

1-TRIMETHYL-2-CYCLOHEXENYL-1-PENTEN-3-ONEASCORBYL 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) CAMELLIA SINENSIS LEAF EXTRACTCan 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 formulationASCORBYL 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 productsACETYL 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 skinGLUCOSAMINE HCLMight be able to stimulate production of skin's natural moisturizing compounds such as hyaluronic acid.

Recent studies show that lactic acid can support the "good" bacteria living on skin's surface (healthy skin microbiome) N-HYDROXYSUCCINIMIDEIs claimed to be able to brighten skin tone by removing some blood-related pigmented compounds in skin (hemoglobin and related elements) but solid research is missing. Can be irritatingNIACINAMIDEIs 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 moisturePALMITOYL 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 activityPISUM SATIVUM EXTRACTMight be helpful in protecting skin collagen and elastin from breaking down but solid research is lackingMAGNESIUM 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 highSTEARYL GLYCYRRHETINATEA fatty acid derived from licorice. Works as an emollient and can help calm down inflammationDIPOTASSIUM 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 lighteningGLYCYRRHETINIC ACIDActive compound of licorice root.

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.

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.

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 radicalsBAKUCHIOLA 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 irritationSULFURADAPALENEA retinoid that is effective against acne and keratosis pilaris.

It is not available over-the counter in many countries, including US and UKHYDROXYPINACOLONE 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.RETINALOne step removed from the biologically active in skin form of vitamin A.
