Formulation and Evaluation of Herbal Sunscreen Lotion Enriched with Natural Plant Extracts

Background: Prolonged exposure to ultraviolet (UV) radiation may result in sunburn, accelerated aging, cutaneous damage, and potentially, carcinoma of the skin. While effective, synthetic sunscreens are frequently linked to dermal irritation and possible toxicity. Herbal sunscreens, formulated with natural, plant-derived compounds, present a more secure and ecologically sound alternative. Objective: To develop and evaluate a herbal sunscreen lotion utilizing plant extracts possessing established UV-protective, antioxidant, and skin-soothing properties. Materials and Methods: Herbal extracts derived from Aloe vera, Watermelon, Sandalwood, and Turmeric were selected based on their photoprotective and antioxidant capabilities. The lotion base was prepared utilizing conventional emulsification methodologies. Physicochemical properties, including pH, viscosity, spreadability, and stability, in-vitro sun protection factor determined via UV spectrophotometry were evaluated for the formulated herbal sunscreen lotion. Results: The herbal sunscreen lotion exhibited acceptable spreadability, stability under diverse storage conditions, and an appropriate pH (5.5–6.5). Confirmation of effective UV-B protection was established by the moderate range (SPF 15–25) of the in-vitro SPF value. The presence of significant antioxidant activity suggested the potential for skin protection from oxidative damage. Conclusion: The herbal sunscreen cream exhibits potential antioxidant properties in conjunction with ultraviolet (UV) protection. It serves as a safe, natural, and efficient alternative to chemical sunscreens, demonstrating commercialization potential.
