A Review On Lycopene Derived From Watermelon Based Herbal Sunscreens

Abstract

The Evolution Of Sun Protection Has Increasingly Shifted From Synthetic Chemical Filters—often Associated With Environmental Toxicity And Adverse Health Effects—toward Natural, Plant-based Alternatives. This Review Explores The Photoprotective Potential Of Lycopene Derived From Watermelon (Citrullus Lanatus), A Potent Carotenoid With Superior Antioxidant Properties. Unlike Traditional UV Filters That Physically Block Radiation, Lycopene Functions As An Internal Biological Shield, Quenching Singlet Oxygen And Neutralizing Reactive Oxygen Species (ROS) Generated By UV Exposure. This Paper Highlights The Distinct Advantages Of Watermelon-derived Lycopene, Specifically Its High Bioavailability Due To The Prevalence Of The Cis-isomeric Form, Compared To Other Sources Like Tomatoes. Furthermore, The Study Examines The Synergistic Efficacy Of Lycopene When Combined With Mineral Blockers Such As Zinc Oxide And Titanium Dioxide, Offering Broad-spectrum Protection While Mitigating Photoaging And Inflammation. Despite Formulation Challenges Regarding Lipophilicity And Stability, Advanced Delivery Systems Such As Nano-emulsions Show Promise In Enhancing Efficacy. Conclusively, Watermelon-derived Lycopene Represents A Sustainable, Reef-safe, And Effective Bioactive Ingredient For The Next Generation Of Herbal Cosmeceuticals.
