Abstract. Free radicals are unstable atoms or molecules with a high level of reactivity caused by the existence of one or more unpaired electrons in their outermost structure. Antioxidants are required to reduce free radical activity because antioxidant compounds can donate electrons to stabilise free radicals. However, because antioxidants are rapidly hydrolyzed and have low stability, the use of the relatively new "lipid-based delivery system" technology can protect and preserve antioxidant stability. Lipid carriers can boost antioxidant penetration in the skin, providing adequate activity, due to their capacity to precisely control the release of drugs or active substances on the target. Systematics Literature Review (SLR) reviewed publications from reliable databases that carried out the exclusion and inclusion criteria. The research found several studies on antioxidant chemicals were included in NLC systems. The NLC system formulation comprises both solid and liquid lipids that have been stabilised using surfactants. The creation of the NLC system has demonstrated that it is still capable of providing antioxidant activity for active chemicals, as seen by the IC50 values.
