Formulation and evaluation of herbal face cream using Manjistha and Bakuchi for skin brightening and anti-pigmentation activity

Abstract

The rising demand for natural skincare alternatives and the adverse effects associated with synthetic cosmetics have determined increased interest in herbal formulations. This study presents the formulation and evaluation of a herbal face cream containing Rubia cordifolia (Manjistha) and Psoralea corylifolia (Bakuchi), both traditionally valued in Ayurvedic medicine for skin-related treatments. An oil-in-water (O/W) emulsion-based cream was developed and estimated for key physicochemical parameters including pH, viscosity, spreadability, and stability, alongside skin irritation potential. In vivo skin brightening and anti-pigmentation effects were preliminarily evaluated through volunteer-based application over four weeks. Results demonstrated good physical and microbial stability. These findings suggest the formulation’s promise as a natural, safe, and effective cosmetic alternative. Further clinical studies on larger populations are recommended to confirm effectiveness.
