Lasers have been used to treat skin lesions
such as birthmarks for over 30 years. Until recently, this treatment
was nonselective in that it destroyed the
overlying skin as well as the lesion so the end result was a scar.
This problem has now been overcome by development of new lasers which recognize
individual colors in skin so that colored lesions can be selectively destroyed
without scarring or change in texture of the skin. By using different lasers,
each designed with an individual target in mind, it is possible to target blood
vessels, tattoos, brown pigment lesions and hair with minimal risk of harming
surrounding structures.

Blood
Vessel Removal
Telangiectasias or so-called broken veins on the face, often part of rosacea,
broken veins on the legs, portwine stains and hemangiomas in children and red-spots
on the body in adults all can be selectively destroyed. The Candela pulsed-dye
laser was the first selective laser and it was designed to destroy small blood
vessels in the skin by recognizing the red color of red blood cells in blood
vessels. The Candela V-Beam is the latest version of this laser and it can
often remove blood vessels without bruising so that downtime is minimal. First
used to treat portwine stain birthmarks, it remains the gold-standard treatment
for all types of vascular birthmarks as well as rosacea and broken veins on
the face.
Anesthesia is usually not required for treatment, post-procedure recovery time
is minimal and scarring or change in texture of the skin is extremely unusual.
The Photoderm, an intense-pulsed light source, is more effective for broken
veins on legs since it can penetrate deeper to reach veins at this site. Unlike
injection treatment of veins, there is no need for limitation of activity or
compression bandaging after Photoderm treatment. Usually a couple of treatments
are required to remove any given vein but large areas, such as a complete lower
limb, can be treated in one session. Blue veins on the leg can also be treated
using the recently introduced long-pulsed Nd/YAG laser.

Brown Pigmented
Lesions
Sunspots, aging spots, freckles and brown birthmarks can be selectively removed
from the skin by targeting melanin in the skin. The Medlite Nd/YAG laser is
two lasers in one and permits destruction of shallow and deep pigment in the
skin. The procedure is quick and relatively painless, post-procedure care is
minimal and the skin usually reverts to a normal color.

Hair Removal Laser
Laser destruction of hair has opened a new era for
treatment of excess and unwanted hair. Selective destruction
of pigment cells in the hair follicles results in a growth delay
of the hair and several treatments cause a progressive reduction
in hair counts. The main advantage over traditional electrolysis
is that large areas can be treated quickly with minor discomfort.
The Epilight hair removal system can remove hair from all parts
of the body and permits a return to regular activities immediately.
Tattoo
Removal
A major goal of selective laser treatment has been removal of tattoos without
causing scarring. Tattoos have been removed by lasers for years but the treatment
has always involved swapping the tattoo for an ugly scar. This has changed.
It is now possible to remove many tattoos and leave behind normal skin. The
Nd/YAG Q-switched laser uses two wavelengths to target multiple colors. The
laser light explodes the pigment in the skin so it can then be removed by the
body. Several treatments are usually required to produce maximal improvement.
Anesthesia is usually not necessary but is available if a tender area is being
treated.

Treatment
of Sunlight Damage and Wrinkles
Several lasers are available to treat aging changes in the skin and wrinkles.
these lasers produce minimal disturbance in the skin so that downtime is greatly
reduced.
Psoriasis Laser
Treatment
A Photomedix
eximer laser is used to treat localized psoriasis. treatments are
quickand painless and usually result in rapid resolution of disease.
This laser is now being used to trat psoriasis on the scalp and we
recently reported excellent results with the treatment. It requires
10 to 30 treatments and often gives long remissions.
