Dermabrasion is a cosmetic medical procedure
in, which the surface of the skin is removed by abrasion
(sanding). It is used to remove sun-damaged skin and to
remove or lessen scars and dark spots on the skin. The
procedure is very painful and usually requires a general
anaesthetic or twilight anaesthesia, in which the patient is
still partly conscious. Afterward, the skin is very red and
raw-looking, and it takes several months for the skin to
regrow and heal. Dermabrasion is useful for scar removal
when the scar is raised above the surrounding skin, but is
less effective with sunken scars. Laser dermabrasion is much
easier to control, much easier to gauge, and is practically
bloodless compared to classic dermabrasion.
Microdermabrasion
Microdermabrasion comes from the above
mentioned technique dermabrasion. Microdermabrasion is a
more natural skin care that is a gentler, less invasive
technology for doing an exfoliation on the skin. The goal of
microdermabrasion is to eliminate the superficial layer of
the skin called the epidermis. If the surface of the abraded
skin is touched, a roughness of the skin will be noticed.
The roughness is keratinocytes, which are better hydrated
than the surface corneocytes. Keratinocytes appear in the
basal layer from the proliferation of keratinocyte stem
cells. They are pushed up through the cells of the
epidermis, experiencing gradual specialisation until they
reach the stratum corneum where they form a layer of dead,
flattened, strongly keratinized cells called squamous cells.
This layer creates an efficient barrier to the entry of
foreign matter and infectious elements into the body and
reduces moisture loss.
Keratinocytes are shed and restored continuously from the
stratum corneum. The time of transit from basal layer to
shedding is generally one month. Corneocytes are cells
derived from keratinocytes in the late stages of terminal
specialisation of squamous epithelia. Microdermabrasion is
done to eliminate some of the corneocytes. These cells are
responsible for the impermeability of the skin. The
minimising or elimination of scars, skin lesions,
blotchiness and stretch marks from the skin can be an easy
process with the use of skin exfoliation. The result depends
on how well the procedure known as skin remodeling works.
Results are optimal and fewer treatments are needed with
more recent and/or superficial scars. Still,
microdermabrasion can be used on scars that showed up during
puberty or many years later.
