Rosella petals contain anthocyanins, and calamansi orange peel essential oil contains limonene, both of which are antioxidant compounds. Antioxidants capture free radicals, allowing them to serve as an active ingredients in preventing premature aging in skincare products such as body lotions. This study aims to formulate and test the antioxidant activity of body lotion preparations containing roselle petal extract (Hibiscus sabdariffa L.) and calamansi orange peel essential oil (Citrofortunella microcarpa). Roselle petal extract was obtained through maceration using a 96% ethanol solvent, while calamansi essential oil was obtained through distillation using water as the solvent. The body lotion was formulated in three variations (F1, F2, and F3) with differing concentrations of roselle extract and calamansi essential oil, respectively: F1 (1% and 3%), F2 (2% and 5%), and F3 (4% and 7%). The formulations were evaluated for their physical properties (organoleptic characteristics, homogeneity, pH, spreadability, viscosity, and stability) and antioxidant activity. The evaluation results indicated that all formulations met physical standards but were unstable under heat. F1, F2, and F3 were semi-solid, homogeneous, pink in color, and had a distinctive calamansi aroma. The antioxidant evaluation yielded IC₅₀ values of 89.9 ppm, 81.7 ppm, and 69.7 ppm for F1, F2, and F3, respectively. The results showed that formula F3 had the highest antioxidant activity. This study demonstrated that increasing the concentration of the combination of roselle petal extract and calamansi essential oil enhanced the antioxidant activity of the body lotion formulations.
