CLINICAL EVALUATION OF 1,550 NM AND
1,927 NM LASER DELIVERED BY FRACTIONAL
FOR ASIAN PATIENTS OF MELASMA AND
ACNE SCARS
Takahiro Fujimoto
ClinicF, Tokyo, Japan
Background: There is a growing demand among patients and
practitioners for a more aggressive treatment to address wrinkles
and uneven texture while minimizing the recovery time
experienced with other ablative technologies. The signs of
superficial photoaging are typically confined to the epidermis and
upper dermis, resulting in a typical pattern of textural changes,
fine lines, wrinkles, and pigmentary alterations. The degree of
photodamage is cumulative and largely age dependent. In young
skin, little or no photodamage is evident. The depth of
accumulated photodamage increases roughly with age reaching a
thickness of approximately 200–250 mm. In this study, we
investigate that clinical evaluation of 1,550 and 1,927 nm laser
delivered by fractional for treatment.
Study: Twenty-four patients, skin types III to IV, age from 20 to
50 seconds were treated with two laser sessions each at our clinic.
Cosmetic skin rejuvenation was accomplished using Fraxel
re:store DUAL (Soltamedical, CA, USA) with & two wavelengths
of 1,550 nm fluence of 4.0 J/cm 2 and 1,927 nm fluence of 10.0 J/cm 2 .
Treatment sites were evaluated compared with the baseline (pretreatment)
regarding the skin texture, pore size, fine wrinkles and
spotty pigments.
Results: At 6 months’ follow-up, the investigators reported
improvement in skin texture, pore size, fine wrinkles and spotty
pigmentation compared with the baseline values. Patients’
satisfaction rate was deferent in each parameter, respectively.
There were no serious complications, including post inflammatory
hyper-pigmentation.
Conclusion: The deep penetrating Erbium fiber laser (1,550 nm)
or the new, more superficial Thulium fiber laser (1,927 nm) offers
a safe cosmetic method of improving skin texture for Asian skin
with no serious adverse sequelae.

MULTIPLE SESSION LOW FLUENCE Q-
SWITCHED ND:YAG LASER TREATMENT OF
MELASMA

Alia Brown, Mussarrat Hussain
Skin Laser & Surgery Specialists of NY and NJ, New York, NY
Background: Melasma is a common pigmentary disorder often
recalcitrant to various treatments. Laser treatments for melasma
has shown inconsistant and unsatisfactory outcome with poor
long-term results. The aim of this study was to evaluate the
efficacy and safety of multiple treatment low fluence 1,064 nm Qswitched
Nd:YAG laser treatment of melasma.
Study: Twenty subjects were treated with a 1,064 nm Q-switched
Nd:YAG laser, using a 6-mm spot size, with fluences of 2 J/cm 2 . All
subjects underwent eight treatments at 1- to 2-week intervals.
The melasma area and severity index (MASI) was assessed at
baseline, 1 month and 6 months after final treatment.
Results: All subjects showed progressive improvement in both
melasma area and MASI evaluations. At 6 months after treatment
12 subjects showed continued improvement while 8 subjects
showed some recurrence of their melasma.
Conclusion: Treatment of melasma with a low fluence Qswitched
1,064 nm Nd:YAG laser can be used as a safe temporary
approach to the treatment of melasma.

LASH WITH A 1,210 NM DIODE LASER IN
SECONDARY KELOID SCAR PREVENTION,
SAFETY RESULTS IN 20 PATIENTS

Background: Keloids scars result from complex alteration of the
wound healing process no treatment consensus has yet been
established. Because of the high recurrence rate and the incidence
of side effects associated with these treatments it remains difficult
to effectively treat them. The use of lasers has been proposed for
scar prevention. The Laser-Assisted Skin Healing (LASH)
technique induces a temperature elevation in the skin which
modifies the wound-healing process. Previous clinical trials
demonstrated an improvement of healing process in skin type I to
IV with 810 nm diode laser. We report a prospective clinical trial
aimed to investigate the safety of 121,078 nm diode laser
treatment as a prophylactic method following surgical resection of
keloid scars.
Study: Twenty patients (age 18–39, Fitzpatrick skin type I to VI)
with keloids scars due to acne, surgery, trauma, were enrolled
in this clinical trial. The laser dose was similar for all patients
and calculated by the device’s software to induce an optimal
thermal shock response. Following surgery scar revision, the
laser was immediately used after skin closure. Each surgical
incision (e.g. presternal area, upper-back, shoulder, arm, lower
limbs, ears) was entirely treated and silicone gel sheeting
applied 15 days post-treatment. Clinical evaluations are
conducted at 15 days, 11 2 , 3, 6, 12, 18 and 24 months. Safety was
documented by adverse effects monitoring at 15 days and
11 2 months follow-up.
Results: No treatment-related adverse effects were reported at
15 days and 11 2 months follow-up. No superficial burns occurred.
Conclusion: This preliminary result demonstrates that 1,210
diode laser treatment, performed immediately after skin closure,
can be used safely in skin type I to VI. The controlled skin
temperature and a homogeneous skin treatment lead to an
adequate safety control.

TRIAL OF LOW LEVEL LASER ACUPUNCTURE
THERAPY FOR SMOKING CESSATION

Preet Kaur, Arun Gupta
New York, NY; Monroe, MI
Background: According to the World Health Organization,
cigarette smoking is linked to more than 5 million deaths
worldwide and 400,000 deaths in America. National surveys
indicate 20% of American adults smoke cigarettes and 70% of
those smokers indicate desire to quit. In this retrospective study,
we investigate the efficacy of laser acupuncture as an adjunct in
the treatment of smoking cessation.
Study: Under IRB approval and FDA stage 2 clinical trials, we
have treated patients since 2005 in a rural community primary
care setting. Licensed technicians were trained to perform a
