Formulation and Evaluation of Poly Herbal Face Cream

This study describes the formulation, physicochemical evaluation, and in vitro/in vivo testing plan for a topical herbal cream containing banana peel powder, papaya pulp and avocado oil intended to reduce facial fine lines and skin aging. A stable oil-in-water (O/W) emulsion is provided with 2 to 5% w/w banana peel powder and 1 to 3% w/w papaya pulp and 8 to 12% w/w avocado oil as the primary lipid phase. The evaluations include organoleptic properties, pH, viscosity, spreadability, percentage of cream consistency (centrifuged / accelerated), microbial limits, DPPH antioxidant dose, total phenol content, in vitro analysis of collagenase and elastase, and a short human skin test, followed by a small controlled clinical evaluation of instrumental skin aging images. The results will demonstrate whether the natural active ingredients provide measurable antioxidant and anti-wrinkle benefits while meeting safety and stability criteria.
