Dermabrasion
Dermabrasion is a cosmetic medical procedure in which
the surface of the epidermis of the skin the stratum corneum 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.
In the
past, dermabrasion was done using a small, sterilized, electric sander.
In the past decade, it has become more common to use a CO2
or Erbium: YAG laser. Laser dermabrasion is
much easier to control, much easier to gauge, and is practically bloodless
compared to classic dermabrasion.
