Using a sea salt scrub for exfoliation involves rubbing sea salt against your skin and the pressure/friction creates the exfoliation. The abrasive action associated with salt scrubs invigorates your skin and helps to improve circulation.
Improved circulation gives skin a natural glow. Scrubbing with salt also helps to remove bacteria from the skin and unclog pores. Salt has antiseptic qualities, and when applied to the skin it may help kill bacteria and reduce inflammation along with any itching and pain associated with bacterial-related skin disease.
Exfoliating with a salt scrub removes dead skin cells, increases circulation, and also encourages regeneration. Sloughing away dead skin cells promotes the growth of healthy new cells.
