Microdermabrasion is a skin-freshening technique that
helps repair facial skin that takes a beating from the
sun and the effects of aging. The plastic surgeon uses
a device like a fine sandblaster to spray tiny
crystals across the face, mixing gentle abrasion with
suction to remove the dead, outer layer of skin. As
with other skin rejuvenation techniques, more than one
treatment may be needed to reduce or remove fine
wrinkles and unwanted pigmentation. |

Your skin is made up of
two main layers, the epidermis and the dermis. The
epidermis is the layer closest to the outside world.
It's a set of dead skin cells on top of another layer
of cells that are in the process of maturing. The
topmost layer is called the stratum corneum. The
stratum corneum mostly acts as a barrier between the
outside world and the lower skin layers. It keeps all
but the smallest molecules from getting through |

When you put lotions or
creams on your skin, some of the moisture passes
through the stratum corneum, but not all of it. This
layer is home to many minor skin imperfections like
fine wrinkle lines and blemishes. |

All of the action in
microdermabrasion takes place at the level of the
stratum corneum. Since it only really targets the
epidermis (and not the dermis), it is more accurate to
call it micro-epi-dermabrasion. Affecting deeper
layers of skin would be painful and harmful, and it
would risk permanently embedding the tiny grains into
the skin. |
