Abstract:
Introduction: The effective sun protection amidst growing concerns about UV radiation’s impact on skin health, the integration of ancient herbal wisdom with modern scientific advancements has gained prominence. This convergence has led to a renewed interest in herbal skincare formulations as alternatives to conventional sunscreens. Rooted in centuries-old medicinal practices, herbal remedies offer a promising avenue for shielding the skin from UV damage while nourishing it with botanical benefits. Objective: This study aims to develop herbal sunscreen creams enriched with polyphenols from Lemon, Tomato, and Aloe vera, evaluate their SPF, assess antioxidant activity, and compare their efficacy with commercial formulations, offering insights into their potential as natural sun protection alternatives. Materials and Methods: The study utilized Lemon (Citrus limon), Tomato (Solanum lycopersicum), and Aloe vera (Aloe barbadensis) extracts as primary ingredients. Extraction methods were employed to obtain bioactive compounds from each plant, followed by phytochemical screening to identify their chemical constituents. The sunscreen formulations were prepared by combining these extracts with excipients such as cetostearyl alcohol, stearic acid, and carbopol. Various physical parameters, SPF values, and antioxidant activity were evaluated to assess the formulations’ efficacy and stability.
