Antioxidant stabilizers are also added to fat-based cosmetics such as lipstick and [[moisturizer]]s to prevent rancidity.<ref>{{Cite journal |date=2007 |title=Final report on the amended safety assessment of Propyl Gallate. |journal=International Journal of Toxicology |volume=26 |issue=3_suppl |pages=89–118 |doi=10.1080/10915810701663176 |pmid=18080874 |s2cid=39562131 |quote=Propyl Gallate is a generally recognized as safe (GRAS) antioxidant to protect fats, oils, and fat-containing food from rancidity that results from the formation of peroxides.}}</ref> Antioxidants in cosmetic products prevent oxidation of active ingredients and lipid content. For example, phenolic antioxidants such as [[(E)-Stilbene|stilbenes]], [[flavonoid]]s, and [[hydroxycinnamic acid]] strongly absorb UV radiation due to the presence of [[chromophore]]s. They reduce oxidative stress from sun exposure by absorbing UV light.<ref>{{Cite journal |last1=Débora |first1=Jackeline |last2=Cleide |first2=Viviane |last3=Luciana |first3=Oliveira |last4=Rosemeire |first4=Aparecida |date=August 7, 2019 |title=Polyphenols as natural antioxidants in cosmetics applications |journal=Journal of Cosmetic Dermatology |volume=19 |issue=1 |pages=33–37 |doi=10.1111/jocd.13093 |pmid=31389656 |s2cid=201156301}}</ref>
