This energizing face scrub from Jack Black effectively clears the way for an easier shave by smoothing the surface of your skin. This deep-cleaning pre-shave cleanser and scrub contains small scrubbing particles that remove dirt and dead skin cells for a less-irritating shave. Your razor is able to get closer, so there's less chance of razor drag or burn. Regular use of a scrub also helps prevent in-grown hairs by opening congested pores. Dermatologist tested.
