FORMULATION AND IN VITRO EVALUATION OF HERBAL FACE SERUM USING ORANGE PEEL EXTRACT

The rising demand for plant-based cosmetic formulations has led to the development of safe, effective, and eco-friendly skincare products. In the present study, a herbal face serum containing orange peel extract as a natural active ingredient was formulated and evaluated in vitro. Orange peel, an agro-industrial waste, is rich in bioactive compounds such as flavonoids, vitamin C, and phenolics, which are known for their antioxidant, antimicrobial, and skin-enhancing properties. A lightweight, fast-absorbing preparation was developed to ensure efficient delivery of active ingredients into the skin. The formulated serum was evaluated for product quality, stability, and user acceptability by assessing various physicochemical parameters, including organoleptic properties, pH, viscosity, and spread-ability. The results revealed that desirable characteristics were exhibited by the prepared serum, such as appropriate pH, good consistency, satisfactory spread-ability, and stability without phase separation. The presence of natural antioxidants from orange peel extract suggests that improvement in skin texture may be achieved, protection against oxidative stress may be provided, and overall skin appearance may be enhanced. Therefore, the successful use of orange peel extract in the formulation of a herbal face serum was demonstrated in the present study, and a promising alternative to synthetic cosmetic products was provided.
