Formulation and Evaluation of Herbal Skin Whitening Cream Containing Red Masoor Dal and Turmeric Extracts

Abstract

The present study was undertaken to formulate and evaluate a polyherbal skin whitening cream containing extracts of Red Masoor Dal and Turmeric, selected for their traditional dermatological applications and scientifically validated antioxidant, antimicrobial, and complexion-enhancing properties. Plant materials were subjected to extraction using Soxhlet extraction and screened for phytoconstituents. The prepared extracts were incorporated into an oil-in-water cream base and evaluated for physicochemical parameters including appearance, pH, spreadability, viscosity, homogeneity, washability, and stability. Skin whitening activity was assessed through in vitro melanin reduction assay, while antimicrobial activity was determined against Staphylococcus aureus using agar well diffusion method. The optimized formulation demonstrated desirable physicochemical stability, good spreadability, appreciable antimicrobial activity, and significant whitening potential. The synergistic activity of protein-rich lentil phytoconstituents and curcuminoid-rich turmeric extract contributed toward antioxidant protection, mild exfoliation, and pigmentation reduction. The findings suggest that the developed herbal cream may serve as a safe, effective, and cosmetically acceptable natural alternative to synthetic skin whitening preparations.
