Acne scarring is what
most teenagers and adults fear. They don't understand that the main
reason for acne scaring is the amateurish way in which they handle
acne. Pinching or pricking acne in an unhygienic manner damages the
skin tissue that is present in and around the acne spots. When this
happens dead cells, injured cells and re-infection combine to create
a scar that can be permanent or temporary.
Temporary scars usually take a longer time to heal. They might
disappear after six months or take as long as two to three years to
fade way. This is the same time that is needed for the removal of
macules or pseudo scars, which are flat reddish spots that remain on
the surface of the skin after the inflamed lesion dies. Sometimes
there is a slight discoloration of the skin in and around the
inflamed region. This can last up to 28 months or more. But it can
become worse if the skin is exposed to excessive sunlight.
The loss of skin tissue at the site of acne leads to the development
of scars. The scars seen on the face are also called ice pick scars.
They are small and the depressions can be shallow or deep. Ice pick
scars, if soft, can be stretched to remove the scar but hard ice
pick scars are unyielding. Ice pick scars over a period of time may
evolve into depressed fibrotic scars. These are quite deep, have
steep sides and are firm and unyielding. Usually surgery is needed
to
remove traces of these scars.
Scarring can also result from excess tissue formation. These scars
are referred to as Keloids or hypertrophic scars, and are caused by
increased production of collagen that accumulates to form an
amorphously shaped scar. They are about 1-2mm in size.
There are several cosmetic and dermatological procedures used to
remove the scar. The simplest method is to inject collagen in the
scarred portion. The collagen lifts the skin and fills soft scars
and small depressions. It is, however, not very effective in filling
ice pick scars. In this case, the treatment needs to be repeated
every three months.
However, before injecting collagen the individual should be checked
for allergy. Those found allergic should then opt for autologous fat
transfer. They can also consider dermabrasion and microdermabrasion,
two latest techniques that are used for erasing scars.
