Laser Hair Removal works
best in lighter skinned, darker haired patients. Because the target
chromophore in hair follicles is melanin pigment, less laser energy is
absorbed by the skin and more by the hair follicle. Tanned skin also "robs"
laser energy as it passes through the skin to the hair follicle. The
infrared YAG and Diode lasers are less dependent on skin color than the ruby
and alexandrite lasers. Because the pigment in the hair is the target for
the laser energy, gray or white hair (which lacks pigment) cannot be
effectively treated with any laser or light-based device.
Multiple laser treatments are necessary for best results: Laser energy has
its greatest effect on growing, or anagen hair follicles; as the dormant, or
telogen hairs become active, usually within 3 weeks to 3 months, some new
hair growth will be observed. Usually at least 3 treatments over the course
of a year will be necessary for satisfactory, long-lasting results. The
female face, armpits, and bikini lines are areas which respond fastest to
laser treatments- backs, arms and legs usually need more treatments over
time. The scalp is very resistant to treatment.
Repeated laser treatments appear to induce a permanent reduction in the
amount of visible hair: Although current studies have shown a "permanent"
reduction in hair growth, some hair regrowth may occur over time, although
this is usually much slower and much finer than before treatment. Imagine a
garden overgrown with weeds-after the first few weeding sessions, only
occasional "touch-ups" are needed. True "permanent" "total" hair removal may
be possible with repeated treatments over time.
How does laser hair removal work?
Lasers have been used for many years for a
variety of medical cosmetic procedures including treatment of facial and leg
veins, age spots and smoothing fine lines on the face. The laser energy is
transformed into heat, which can disable the follicle leaving the
surrounding skin unchanged.
Why is laser preferred for hair removal?
Traditional hair removal techniques, such as
shaving, plucking and waxing, provide only temporary relief. Until now, the
only long-lasting hair removal solution has been by electrolysis - which can
be time-consuming and is usually limited to small areas, because each hair
is treated individually. Laser hair removal is non-invasive, and safely
removes unwanted body hair without damaging the delicate pores and
structures of the skin. Facial and bikini areas are usually completed in
under 45 minutes; legs and larger areas can take longer.
What
does the treatment include?
Depending on the amount of hair and area
treated, the procedure varies from patient to patient. Generally, the
treatment will include: Safety eyewear to protect the patient's eyes
during the procedure from the laser light. A small handpiece will be used to
deliver the laser light. Most experience little discomfort at the treatment
site. The sensation and the degree of discomfort varies with each person. In
some cases, topical anesthesia is an option. Your laser specialist will
discuss this before laser treatment. Depending on the size or number of
areas treated, the time will vary in length from minutes to hours. Patients
can return to work or resume their normal activities immediately following
treatment. The area may become slightly red and may last from a few minutes
to several days depending on the area and skin sensitivity.
What precautions should be taken before and after treatment?
If you are tan or have a darker skin
type, a bleaching cream should be started 4-6 weeks before treatment for our
melanin absorption lasers.
How many treatments will I need?
Hair grows in cycles. The laser is only
effective on hair in its actively growing cycle. At any one time there will
only be certain hairs in that growing phase. This means that consistent
treatments at appropriate intervals are absolutely necessary for the best
possible results. The number of treatments required depends upon your skin,
hair coloring, coarseness of the hair and density per treated area. Everyone
will require at least 2-3 treatments as the process is only effective on
hairs during their growing cycle. Additional treatment will be necessary to
treat other follicles when they re-enter the growth phase and produce new
growth.
