'LASER BEAMED'
Imagine
a hair-removal treatment that doesn't involve regular battles with razors,
hot wax, or lotions that smell like a chemical plant. Laser hair removal may
sound like something out of star wars but, believe me, its the greatest
beauty breakthrough since the invention of the blow-dryer.
I was initially skeptical
when I set off to investigate this futuristic sounding miracle.
Anyone who passed O level
physics will be pleased to hear that the laser works with low energy. Those
who failed the exam should content themselves with the knowledge that it's
gentler than other laser treatments and suitable for all skin colors.
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.

Power,
Wavelength and Tissue Penetration
|
|
The
most efficient wavelength required to achieve results by laser is in
the 670 to 890 nm (nanometer) range. This particular frequency allows for the
greatest tissue penetration without loss of photon intensity through the
dermis(2). This range is also highly selective (as well as reactive)
with follicle melanin
and carbon dye.
The amount of
power required for this range to reach the papilla
matrix varies with the
depth of the follicle pore. There are generally 3 types of hair growth:
terminal (deep), secondary (medium) and vellus (shallow). Terminal hairs
usually extend 7-8 mm into the dermis and require around 10 Joules per CM2 of
photon intensity at the surface of the skin to create adequate thermolysis in
the papilla matrix to destroy the tissue(3). Secondary hairs grow to
about 5-6 mm in depth and require ≈5 JCM2. The lightest hairs need
roughly 2 JCM2. These vellus hairs are most common on upper lips of adult women
and normally respond very well laser epilation.

Faster Than Regular Electrolysis
|
|
The
advent of this new technology has created enormous excitement in the field of
epilation cosmetology, and with good reason. Laser hair removal is simply the fastest
way to remove unwanted hair currently available. It is very easy and highly
effective. The laser can completely clear the leg hair growth on an average
woman in under one hour. The same area would require more than 40 hours
of needle electrolysis.
Discussion
In this study the laser treatments given
every six weeks yielded better long-term clinical results than the treatments
given every two weeks. Previous studies [1-5] have demonstrated good to
excellent results for treatment intervals between four and eight weeks. An
earlier study done by the investigators [6] demonstrated excellent long-term
hair reduction using three-week treatment intervals. Mathematical modeling
showed that better laser penetration was achievable at the hair bulb and bulge
in the absence of terminal hair shafts extending to the skin surface. It was
recognized that the success of a hair removal treatment at a shortened treatment
interval was dependent on the regeneration of melanized target structures for
the follow-up treatments [6]
The poor long-term results seen with the
shortened treatment interval would suggest that the laser treatment given only
two weeks following the initial treatment did not yet have an adequate target to
absorb the laser's energy. It is hypothesized that the hair bulb has not yet
regenerated at two weeks and hence the laser treatment was ineffective. The
six-week interval allowed adequate time for the hair bulb and follicle to
regenerate therefore providing an adequate target for the laser and hence, a
more effective long-term result.
Conclusions
The treatment intervals chosen for laser hair removal strongly affect
the efficacy of long-term results. This study demonstrates better efficacy at
the six-week treatment interval compared with the two-week treatment interval.

1. Am I a candidate for laser hair removal?
Laser hair removal is not for everyone. The absolute requirement is that
one's hair must be darker than the surrounding skin. Additionally very
darkly pigmented people absorb too much laser energy in their skin and are
not candidates. Tanned patients with light hair are not candidates. Tanned
patients with dark hair must wait until their tan fades before they can be
treated. Lastly the treatment cost should be within reach of the patient.
Laser hair removal, although much less expensive than electrolysis, requires
multiple treatments, and generally costs over $1000 in total for most
anatomic areas. 2. What will it cost for laser hair removal for me?
Treatment cost varies with the size of the area treated. Experienced laser
centers, which have developed expertise in laser hair removal, generally
average about $500 per treatment session, with an average of four treatment
sessions initially recommended. Large areas, such as the entire back, or the
entire legs, cost considerably more than this. Small areas, such as the
upper lip, can be less. Individual consultation with the laser center is
necessary to obtain exact pricing. 3. Influence of skin color on
laser hair removal. Light skin makes laser hair removal easier to
perform. Fewer treatments are required, and better, faster results are
obtained. People with darker skin can be treated, but results are slower,
more sessions are required, and greater expertise is required on the part of
the laser center. Laser hair removal must be individualized for each
patient. 4. Influence of hair color on laser hair removal.
Dark hair absorbs more laser energy and is easier to treat. Coarse dark hair
responds the best to laser treatment. Light hair is more difficult to treat.
Blonde or red hair is very difficult to treat. Multiple treatment sessions
are required, and results are variable. Blonde or red hair usually contains
pheomelanin, which absorbs laser energy less avidly than the eumelanin
pigment which is present in black or brown hair. 5. Laser hair
removal requires multiple treatments. Although one laser session
can produce long-term hair removal, as a rule multiple treatment sessions
are necessary to obtain optimal results. In large part this is due to the
fact that laser hair removal is most effective for hair which is in the
anagen phase. Anagen is the growth phase of hair. Since hair grows in
cycles, not all of the hairs are in anagen at any given time. Additional
sessions are necessary to catch all of the hairs when they are in anagen.
6. What areas can be treated? Any area, except adjacent to the
eye, where there is excess hair. The most common areas requested are the
face, upper lip, neck, chest, periareolar, underarms, back, abdomen, bikini
line, and legs. 7. About permanent hair reduction by laser.
Waxing, shaving, and plucking all produce hair removal which is temporary.
Several of the newer lasers have clearly documented that there is permanent
hair reduction after each treatment. The FDA has approved several lasers for
permanent hair reduction, and more results with additional lasers are
pending. The results tend to be additive, i.e. more treatments lead to
greater degrees of permanent hair reduction. For any given patient results
cannot be precisely predicted. Results can be variable, even with the best
lasers. 8. Pulsed light and laser hair removal. Intense
pulsed light devices can produce effective hair removal. Although these
devices are not lasers, they are "laser equivalents", utilizing the same
principle of selective photothermolysis to achieve hair removal. These
devices are in practice more difficult to adjust than lasers and require
great expertise for their proper use. 9. Myths 1: Guarantees in
laser hair removal. It is impossible to predict the exact result a
patient will achieve with laser hair removal, especially with regard to how
many sessions a given individual will require. Many of the hair removal
clinics which guaranteed results have gone out of business. Like most
reputable medical practices, the most established laser hair removal
practices do not guarantee results. 10. Myths 2: Discount laser
hair removal clinics. Established medical centers with excellent
reputations do not discount their fees. Patients know their reputations and
rely upon their experience and expertise. The same is true for laser hair
removal. Consumers are advised, as with all forms of medical care, to seek
the center of highest quality, rather than lowest cost. Laser hair removal
requires exacting science, individual attention, experience, and a trained,
caring, professional staff.11. Myths 3: Laser hair
removal limitation of effectiveness.
Contrary to the statements of those unfamiliar with this new technology,
laser hair removal is effective when properly performed for the great
majority of candidates. Non-responders are usually limited to those with
blonde or red hair. 12. Qualifications of laser hair removal
personnel. Requirements vary by state. In California laser hair
removal can only be performed by a licensed M.D., R.N, or Nurse
Practitioner. Electrologists, Medical Assistants, and other unlicensed
personnel cannot perform laser hair removal. 13. Importance of
experience in selecting a laser hair removal facility. Experience
is crucial in selecting the proper laser parameters to use for any given
area for any individual patient. Centers with the most experience generally
have the best results. 14. Tanning and laser hair removal.
Tanning and laser hair removal are not compatible. Tanning prior to the
procedure will necessitate turning the laser power down, thereby reducing
the effectiveness of the treatment. 15. Adverse treatment
reactions. Pigmentary change of the skin treated can occur,
including either dark or light areas. Pigmentary changes may persist for
months, but are almost always temporary. They are very rare in patients with
fair skin who are untanned. Blisters and burns are rare but occasionally
occur, particularly in patients with dark skin. 16. Diet and laser
hair removal. Diet is generally unrelated, except for
Beta-Carotene, which interferes with the treatment. 17.
Beta-Carotene and laser hair removal. Beta Carotene, found in
carrots, vitamin A supplements, squash, and other vegetables, is deposited
in the skin, producing a subtle orange or yellow color in the skin. This
pigment absorbs laser energy, preventing it from reaching the hair follicle,
and increasing the absorption of laser energy in the skin. Beta carotene
persists for months after ingestion. Patients interested in the best results
from laser hair removal will benefit from discontinuation of the use of all
forms of beta carotene. 18. Laser hair removal and children.
Laser hair removal is successful for children but it does require their
cooperation. 19. Laser hair removal for African-Americans.
The darker one's skin, the more difficult it is to obtain adequate
results from laser hair removal. The darker one's skin the more sessions one
requires and the greater the chance of an adverse result. Laser hair removal
can be successful for African-Americans with light skin and coarse, dark
hair. 20. Laser hair removal for other people of color.
The best results are obtained when the hair to be treated is considerably
darker than the surrounding skin. Also coarse hair is easier to remove.
Fine, light hair in people of color is difficult to remove. 21. Who
should not have laser hair removal. Patients with a recently
acquired dark tan. Blondes or redheads with any recent tan. People of color
with fine, light hair. Anyone who cannot afford multiple sessions (one
treatment is rarely adequate). 22. How to assess a laser hair
removal facility. Research the qualifications of the Medical
Director of the facility. Is he or she Board Certified in Dermatology? Is
there more than one Board Certified Doctor on the staff? Are all personnel
performing the procedure licensed physicians or Registered Nurses? Is the
facility affiliated with an academic medical center? Is the atmosphere
professional? Remember this is a medical procedure, and should be selected
with the same care you give to selecting a surgeon. |
