The present study focuses on the formulation and evaluation of a herbal-based sunscreen stick incorporating Persea americana (avocado) oil extract, known for its natural emollient, antioxidant, and UV-protective properties. The objective was to develop a skinfriendly, stable, and effective topical formulation offering broad-spectrum sun protection using plantderived ingredients. The sunscreen stick was formulated using a blend of natural waxes, butters, and oils, with Persea americana oil serving as the key active component due to its high content of vitamins A, D, and E, and essential fatty acids. The formulation was evaluated for various parameters, including physicochemical characteristics, spreadability, melting point, pH, stability under different environmental conditions, and in vitro sun protection factor (SPF). The results indicated that the sunscreen stick exhibited favourable physical properties, good stability, and an SPF value indicative of moderate to high protection. The findings support the potential of Persea americana oil as a natural alternative in the development of effective, herbal-based sunscreen formulations
