Enhancing Skincare Formulas with Olive Oil-Infused Citrus Peel Extracts: A Comprehensive Study

Abstract

The increasing global demand for natural and organic ingredients in cosmetics has spurred a surge in research exploring innovative formulations. This study delves into the utilization of citrus fruit peels and seeds macerated in olive oil as a foundation for novel ointments. Through the analysis of extracts from a variety of citrus sources, including orange, lemon, tangerine, grapefruit, and citron peels, as well as lemon and tangerine seeds, their physicochemical properties and antioxidant activity were meticulously examined using thin-layer chromatography (TLC). A groundbreaking aspect of this research is the revelation of the in vitro antioxidant potential of DMSO extracts obtained from these citrus-infused olive oils. Chemical assays unequivocally confirmed the presence of phenols and flavonoids, renowned for their robust antioxidant properties, across all extracts. These significant findings not only reinforce the well-documented benefits of citrus fruits in combating premature aging and diseases but also underscore the untapped potential of citrus by-products as valuable natural cosmetic ingredients. This preliminary investigation serves as a beacon illuminating the promising prospects of integrating citrus fruit remnants into cosmetic formulations. The imperative for further exploration in this realm is evident, aiming to refine formulations and advocate for the sustainable exploitation of citrus resources within the cosmetics sector. By embarking on deeper research endeavors, an inclusive comprehension of leveraging the inherent potency of citrus fruits for the creation of cutting-edge and efficacious natural cosmetic products can be achieved.
