Wild Ferns Rotorua Mud Body Scrub with Lemongrass. 250ml. A gentle body scrub containing thermal mud from Rotorua and the uplifting essential oil of Lemongrass. Mineral rich thermal mud penetrates the pores to purify and perfectly cleanse, yet allows the skin to retain its natural moisture. Lemongrass helps stimulate the circulation to tone and refresh. Naturally occurring fine salt is used as the exfoliating ingredient in this energising body scrub. Regular use will bring back radiance to dry, dull skin.
