Skin is the protective outer covering that acts as insulator between internal and external environment. Skin diseases are the major problem nowadays. Mostly skin problems are raised due to the oxidative stress. Synthetic compounds and drugs are available in the market but they contain toxic compounds that are carcinogenic and leads to the cancer. Herbal and natural products are preferred as they contain natural antioxidants. In the present study extracts of different solvents at various concentrations of five plants Aloe barbadensis, Camellia sinensis, Cocos nucifera, Ficus carica and Rosa indica are selected for experiment to evaluate their antioxidant potential by DPPH, TPC and Total Antioxidant Assay. Among all the plant extracts 100% v/v Petroleum ether extract of Aloe barbadensis showed the highest radical scavenging value i.e. 98.6±0.55d. After the screening of all the extracts by the DPPH, TPC and Total Antioxidant Assay the combination of five plants is concluded. These plant extracts can be used in cosmetics and other industry as the source of natural antioxidants.
