The use of natural ingredients in cosmetics has grown due to the demand for safe and sustainable products. This study developed and evaluated the phytochemical profile and antioxidant activity of a vegan facial serum formulated with hydroalcoholic extracts of Mangifera indica and Syzygium cumini and nanoemulsions of essential oils of Syzygium aromaticum, Schinus terebinthifolia and Citrus × latifolia. The extracts were obtained by maceration with 70% ethanol and the nanoemulsions by the phase inversion method. The quantification of total phenols and flavonoids was performed by spectrophotometry and the antioxidant activity by the ABTS and DPPH methods. The serum showed high total phenol content (173.09 mg EAG/g) and low concentration of flavonoids (0.21 mg EQ/g), with high antioxidant activity (CI₅₀ ABTS = 0.42 mg/L; DPPH = 2.64 mg/L). The nanoemulsions of S. aromaticum and S. terebinthifolia were also active, while C. × latifolia did not show activity. It is concluded that the developed serum has a relevant phytochemical profile and remarkable antioxidant activity, enhanced by nanotechnology, configuring itself as a promising alternative for dermocosmetic application.
