Skin exfoliation in the removal of dead skin cells. When you get rid of all the dead cells on the surface, you expose the new and radiant skin underneath.
How often should you exfoliate?
If you have delicate or sensitive skin, twice a week might be too much and could cause some irritation. On the other hand, if you live in a warmer climate or your skin is naturally oily, you might have to exfoliate your skin more than twice a week to accommodate a higher build up of dead skin cells.
