Acne vulgaris is a common dermatological disorder caused by excessive sebum production, microbial infection, follicular blockage, and inflammation. Conventional synthetic anti-acne products often produce adverse effects such as irritation, dryness, and hypersensitivity reactions. Therefore, herbal alternatives with improved safety and efficacy are gaining increasing importance in cosmetic and pharmaceutical industries. The present study aimed to formulate and evaluate a herbal anti-acne soap incorporating wood apple (Limonia acidissima) extract as an active ingredient. Wood apple possesses antimicrobial, antioxidant, and anti-inflammatory phytoconstituents including flavonoids, tannins, phenolic compounds, and alkaloids. The extract was prepared 'using solvent extraction techniques and incorporated into soap using a controlled saponification process. The formulation was evaluated for physicochemical parameters such as pH, foam height, hardness, moisture content, antimicrobial activity, skin irritation potential, and stability studies. The prepared soap showed acceptable organoleptic characteristics, suitable pH range, good foam stability, and significant antimicrobial activity against acne-causing microorganisms. Stability studies confirmed formulation integrity under different storage conditions. The study concludes that wood apple extract can serve as an effective natural ingredient in anti-acne soap formulations offering improved safety, affordability, and therapeutic potential.
