Bakuchiol is a plant-derived antioxidant extracted from Psoralea corylifolia seeds that functions as a functional analog to retinol by stimulating similar gene expression pathways for collagen production and cell turnover. A landmark randomized trial published in the British Journal of Dermatology found that topical bakuchiol reduced fine lines and hyperpigmentation as effectively as retinol, but with significantly less skin peeling, stinging, and redness. As a result, bakuchiol serum is considered a milder, highly tolerable alternative for those seeking anti-aging benefits without the typical irritation caused by traditional retinoids, particularly individuals with sensitive skin.
