Abstract

This study evaluated the antioxidant potential of Camellia sinensis by quantifying its bioactive compounds, which contribute to the treatment of melasma. Consequently, developing a sunscreen formulation enriched with Camellia sinensis extract was proposed. The findings were derived from physicochemical and microbiological analyses supported by bibliographic references. By determining the phenolic compound content in four different concentrations of Camellia sinensis extract, the highest percentages of gallic acid were identified in two concentrations. These results highlight the extract's antioxidant and photoprotective properties against free radicals and its promising potential to inhibit the activity of the tyrosinase enzyme.
