Tomato-Derived Lycopene Emulgel Shows SPF 38.8 Protection
A team of Algerian and Portuguese researchers has successfully developed a novel emulgel derived from tomato lycopene, demonstrating significant photoprotective capabilities. The formulation, led by Sarah Boukhalkhal of Amar Telidji University in Laghouat, Algeria, achieved an in vitro sun protection factor (SPF) of 38.8, a figure comparable to commercial SPF 50+ sunscreens. Published in Plant Biosystems, this research highlights the potential for new natural skincare products that also offer antioxidant and antimicrobial benefits.
The study focused on isolating and characterizing lycopene from Solanum lycopersicum, purifying the pigment, and embedding it into a stable emulgel for topical application. Beyond its impressive UV protection, the purified lycopene exhibited strong antioxidant activity, neutralizing free radicals with high efficiency. Additionally, it showed significant antimicrobial action against various skin-relevant pathogens, including Staphylococcus aureus, methicillin-resistant Staphylococcus aureus (MRSA), Micrococcus luteus, and Candida albicans, addressing challenges posed by antibiotic resistance.
This multifaceted discovery by researchers from Amar Telidji University and the University of Aveiro in Portugal offers a promising plant-based alternative to synthetic UV filters and chemical preservatives. The multifunctionality of this single plant-derived ingredient could simplify product formulations and cater to the growing demand for natural and sustainable skincare solutions. While further research, including clinical trials and stability studies, is required, this development positions Algerian scientific innovation at the forefront of natural dermatological advancements, creating opportunities for practical applications in the cosmetic and pharmaceutical industries.
