Exfoliation is a naturally occurring physiological process whereby dead surface skin cells, naturally slough off, and reveal new skin cells. This process naturally takes a long tme, but you can help it along. It is a kind of skin treatment which helps to speed up the process of skin flaking and shedding, by taking off the uppermost, dead layer of cells to expose the finer part. Exfoliation is an important part of both facials and body treatments. When done correctly, exfoliation leaves the skin feeling smoother and fresher looking. Exfoliation also makes penetration easier for expensive facial products like serums.
