Pigmented lesions
(red spots on skin, brown spots, skin sun spots) which tend to
be brown or black color are caused by an excess number of pigment
producing
cells in the skin known as melanocytes. When stimulated
by hormonal changes or exposure to ultraviolet light the melanocytes
produce
large amounts of melanin resulting in dark discolorations of the
skin. Age spots, sun spots, moles, freckles, lentigos, melasma
and blue and
black birthmarks known as congenital nevi are common examples of
these changes in the skin. There are a number of treatment options
for these conditions which include cryotherapy, surgical removal,
and bleaching creams. Lasers have provided treatment options
which
in some cases have significantly reduced the risk of scarring or
have provided an alternative when other treatment options are
ineffective.
How does the laser work?
An intense light from
the laser passes through the top layer of the skin and is selectively
absorbed by brown, black or blue pigment
particles within the skin. The energy emitted by the laser light
when it is absorbed causes the melanosome in the pigment cells
to
break into miniscule particles which are removed by the body’s
immune system.
What is Intense Pulse Light Therapy?
Intense xenon
light is applied to the skin through filters in a series of
gentle pulses. The filtered light of a specific wavelength penetrates through the
skin and is absorbed by the abnormal pigment or vasculature in
the skin. It produces a bright light, mild
discomfort, a little swelling, contraction of blood vessels,
and/or darkening of pigmented spots that subsequently peels off.
The IPL is effective in the treatment of sun related aging,
including: dilated blood vessels and broken capillaries (redness)
and pigment abnormalities (brown discolorations such as lentigos and
actinic freckles).
The heat
delivered during the IPL and Genesis treatment may result in
the reorganization of the collagen building blocks of
the skin resulting in a reduction of the appearance of pores, fine
lines and texture changes. The skin looks revitalized.
The advantage of the IPL over other types of pigment and
vascular removal methods is that it is fast, the recovery time is
short, and the risk of side effects are low. The procedure
simultaneously addresses a variety of concerns including broken
capillaries, rosacea, diffuse redness, age spots, freckles, diffuse
pigment, enlarged pores, fine lines and mild texture changes.
What can be expected during a treatment?
Prior to treatment
the target area must be free of all make-up and creams and must
be shaved. Eye wear is worn by the patient and
doctor to protect the eyes from the bright light. The area to be
treated is cleansed and the filtered light is applied through
a hand
piece. Genesis will gently warm the skin and feels like you have
been sitting in the sun for an hour. Each pulse of the laser
feels
like the snap of an elastic band on the skin. A treatment may
take anywhere from 15 minutes to an hour depending on the size of
the areas being treated.
Do treatments with the laser hurt?
The light from the laser is emitted in pulses. Each pulse feels
like someone has snapped an elastic band against the skin. Most
patients find this treatment quite comfortable.
How does the skin look and feel after a treatment with
the laser?
Each
pulse of the laser light turns the targeted skin gray. Within
minutes the targeted skin turns to a dark, superficial crust. The
crust remains until the top layer of the skin turns
over, leaving a pale, pink
and smooth surface. The length of time it takes for the crust to
be sloughed depends on the type of condition being
treated and where on the body it
occurs. The crusting of an age spot on the face will turn
over faster than one on the back of the hand. On average, the
process takes one to two weeks. The new underlying skin will gradually
change from a pink shade to the color of the surrounding
skin in a couple
of weeks.
The Genesis laser will turn the skin pink for up to two hours and
then it will return to its baseline color.
How many treatments are required and what will it
cost?
The
number of treatment sessions depends on the size, location, depth and
color of the pigmented lesion. These factors also determine the cost.
Superficial
lesions such as age spots usually require fewer sessions than
a deeper lesion such as a congenital nevi. The latter
often requires a layered approach which will take several sessions.
In certain instances, not all of the pigment can be removed.
Treatment sessions are spaced 3 to 6 weeks apart. This allows the
garbage collecting cells of the immune system to gather up the
maximum amount of left over pigment between each session.
Are the laser treatments safe?
Yes, the laser is safe.
Safety goggles must be worn by both the
patient and the physician during the procedure to protect the eyes from
the bright light.
A potential complication with this procedure is hypopigmentation
where the treated area ends up being lighter than the surrounding
tissue. The risk of scarring is very low because the laser light is
absorbed by the target pigment, leaving the surrounding tissue
relatively untouched. Infection is possible, but unlikely, if the
lesion is properly cared for by the patient after the treatment.
What does treatment cost?
Cost is determined on a per treatment basis and is dependent on
the size and complexity of the pigmented lesion. More than one
session may be required.
