Introduction to laser treatment
Acne or Acne Vulgaris as it is medically called
is one of the major skin disorders worldwide. 25
million adults and 40 million adolescents suffer
from this ailment in US itself. It is unimaginable
as to how many people suffer from it in the rest
For some people acne vanishes with age, but even
then, there are people who are left with such unpleasant
scars on their face or other exposed areas, that
it becomes a permanent mark for the rest of their
lives. This is the reason why proper treatment
at the proper time is very much required for such
severe cases, before it becomes a matter of concern.
Modern medical techniques have come up with several
treatments, which are not only painless but also
cost effective. This makes the treatment reach
a vast number of people makng this skin disorder
a matter of the past or just a part of growing
Laser for acne prevention
Laser surgery has been in use for some time to
reduce the scars left behind by acne, but research
has also been done on lasers for prevention of
acne formation itself.
Laser acts as the amplifier of light ray, produces
a much-concentrated ray of light that can be focused
on the affected area. As compared to oral therapies,
such as intake of pills, laser takes less than
half the time in curing the acne problem in people.
Laser has become one of the leading treatments
in various other conditions like eye operation,
any form of cancer as well as in the treatment
There are several types of laser treatment for
- Potassium titanyl phosphate laser (532
- Pulsed Dye Laser
- Diode Laser
- Er.glass Laser
- Photodynamic Therapy
titanyl phosphate laser
This was the treatment, which was faced with least
side effects and also had a long lasting effect
of almost 4 months without any kind of relapse.
This treatment accompanied with topical therapy
for almost 6 weekly sessions worked very well on
the patients having inflammatory lesions, in this
Pulsed Dye Laser
In this treatment a consistent yellow beam of
light is applied to the affected area of the skin.
This light is supposed to attack the oxyhemoglobin
in the microvessels. But this treatment is said
to have some discoloration on the skin, thus suggesting
people with darker skin tone to avoid going for
This treatment is opted mainly for facial rejuvenation.
The laser works on the water content of the uppermost
layer of the skin and thus improves the formation
of collagen. This is turn helps in the elasticity
of the skin. In this process, there was a marked
decrease in the formation of acne too.
This is the midinfrared range of laser treatment
and works on the water content of the dermis. Patients
were given four sessions in an interval of 2 weeks
and had a marked improvement on their acne problem.
The side effects are minimal and thus are quite
a suggested option for acne.
This treatment, commonly known as PDT though a
bit painful is often the most effective in treating
acne. As this deals in light rays, which are not
only sensitive to the skin but also damages cells
that are helping in the formation of pimples.
PDT has two main compounds, which are used in
their procedure, they are described below:
Aminolevulinic Acid: This is the compound which
acts on the sebaceous or sweat glands and tries
to shrink as well as
destroy the gland which is forming the lesion.
A weekly session for 3 weeks gives a very long
lasting effect on the acne, preventing them from
re-appearing for almost 8 months.
Indocyanine Green: This compound is a kind of
a dye which is mainly used in many other pathological
test where photosensitive
diagnosis is required. This is topically applied
on the affected areas and it very conveniently
accumulates in the sebaceous glands. After application
of this Indocyanine Green (ICG), the area is then
treated with laser so as to eradicate the lesions.
The above-mentioned treatments were tried over
patients suffering from this disorder. The main
motive of all these treatments was to come to a
conclusion as to the effectiveness of the therapy,
the longivity of the effects of the treatment as
well as the amount of side effects (if there are
any side effects).
The therapies are in a way subjective too, as
each patient has their typical symptoms and their
response to the therapy was unique. At the same
time, the severity of the disorder is also taken
into account, and accordingly therapies suggested
We can conclude by saying that laser treatment
is a very good alternative for patients who is
unwilling to take drugs orally, and who are scared
to get exposed to the side affects of anti-biotics.
Nevertheless, laser treatment along with medication
can have a faster and prolonged positive impact
on patients' acne.
