all types of skin (dry, normal, and oily) benefit from the removal of dead skin cells 

most exfoliation techniques use a slightly abrasive material to rub the skin, 
scraping away any dead cells on the skin’s surface,
increasing circulation, removing toxins and giving skin a healthy glow

what is a Salt Glow?

one way to exfoliate the skin is by using salt. a salt glow, also known as a salt rub or salt scrub
is a circulatory stimulant that removes dead surface cells and dirt, leaving skin soft and gleaming

salt scrubs encourage the skin to secrete sebum (the natural skin oil) 
and they can be used on all parts of the body except the face and neck
