Formulation and Evaluation of Polyherbal Pigmentation Skin Serum

A novel poly herbal skin serum was formulated for depigmentation, using Psoralea corylifolia (Bakuchi) seed extract as the key active ingredient. The serum base included green tea extract, glycerine, niacinamide, Tween 20, sodium benzoate, and lavender oil. Three batches (F1, F2, F3) with 15%, 12%, and 10% Bakuchi extract respectively were prepared and evaluated. All batches were stable and non-irritating over 30days. The 15% Bakuchi formulation (F1) showed the highest efficacy in reducing dark spors and improving skin moisture in volunteer tests. These results suggest that the Bakuchi-containing serum can safely ligten hypo pigmented skin areas while providing hydration, offering a natural alternative to conventional chemical depigmenting agents.
