Body scrubbing automatically means exfoliation. Exfoliation is the process of of removing dead skin cells from the outer layer of your skin so as to make the skin look more beautiful.
Body scrub which could be sugar or salt type is what you apply on your body but what it does to your skin is exfoliation.
Even dermatologists confirmed exfoliation to be great for the skin especially if done once or twice in a week.
Imagine the combo of exfoliation and the other skincare products you use, just imagine how radiant your skin will look.
