The scent of lilac is a joyous infusion of early summer, the color of a cloud dappled lavender blue early morning sky. This Castile soap is also enhanced with an extra measure of vegetable glycerine: a humectant that assists your skin to hold onto its natural moisture. The antioxidant properties of Vitamin E provides for healthy skin cell renewal. This lovely soap is one of the most enduringly popular recipes in my repertoire.
