• had a long-term effect due to the stability of EGCG. The findings of the study underline the potential of antioxidant and antiaging effects of the developed ethosomal formulations for use in the cosmetic field. Keywords: antioxidant effect; antiaging effect; epigallocatechin gallate; ethosomal gel

• different plant extracts other than EGCG [15]. In this current study, we aimed to develop ethosomal formulations for the use of EGCG in cosmetics due to its widely known strong antioxidant effect, which has been emphasized in many studies. In addition, we focused on enhancing the long-term antioxidant

• dose determined based on cell viability results of 50% or more is appropriate [22][28]. In previous studies, the cytotoxic effect of EGCG, whose antioxidant effect has been proven many times, has been investigated, especially on cancer cell lines. Although there is no cytotoxicity study on the L929

• size and the EE of TOC. Antioxidant effect of NLCs containing TOC Following the results obtained in the 2D cell model, the study of the protective effect of NLC T10-TOC was carried out on HSE. CS contains many components able to elicit oxidative stress, which can induce the cytoprotective enzyme heme

• exerted no difference on the ROS scavenging activity. The results suggested that phenolic compounds immobilized on the γ-Fe2O3 nanoparticles preserved their antioxidant effect to reduce ROS levels inside the cells. Conclusion Magnetic nanoparticles are increasingly used for biomagnetic separation

• source and catalyst. The proposed mechanism for the formation of the MWNTs from graphene is as follows [31]: (1) the production of graphene layers by ultrasonication of graphite in DMF, (2) the antioxidant effect of Fc–CHO which reduces the concentration of radical reactive species, reducing the cutting
