Results of antioxidant activity studies: (a) Antiradical activities of human skin extracts after applying semi-solid formulations with a mixture of phenolic compounds solution; (b) The dendrogram illustrates variation in the antioxidant activities of human skin extracts after applying semi-solid formulations with a mixture of phenolic compounds solution. Uppercase and lowercase letters indicate a statistically significant difference in the antiradical activities between semi-solid formulations (p < 0.05).
