Participant Flow

All patients who had undergone direct brow lift within the last three years were contacted by telephone, and an approved script was used for recruitment.

Exclusion criteria included unilateral procedures, age less than 18 years, pregnancy, history of photodermatoses or adverse outcomes associated with laser, history of isotretinoin use within the prior six months, and active use of other scar treatment in the brow area.

Measure
Laser Treatment and Control Group
Each patient was randomized to have one of two scars treated with Laser Genesis and a scar not treated with Laser Genesis, which was used as a control. Patients were not allowed to undergo laser or any other scar treatments with the exception of sun protection for the control scar for the duration of the study. The laser treatment was administered by manually scanning the rapidly pulsed laser in an even, painting motion throughout the entire treatment zone. The eyebrow hairs were covered with white tape to prevent inadvertent alopecia. The laser handpiece was oriented perpendicular to the skin at all times, at a distance of 1-2 cm. Patients were instructed throughout to give verbal feedback regarding if the area was "too hot" as an additional safeguard against epidermal damage. Laser treatment: Non-ablative, non-fractional, microsecond-pulsed Neodymium:Yttrium/Aluminum/Garnet laser 500-1000 pulses, 0.3 msec pulse duration, 10-14 J/cm2, 5 mm spot size

PRIMARY outcome

Timeframe: 1 month after final treatment

Population: 3 graders masked to treatments were asked to judge side-by-side photographs of first and final visits for which scar improved more. Each pair of before-and-after photos was graded twice by each examiner. Results are percentage of times treated scar was chosen by examiners as most improved (an analysis of 6 results per pair of photos).

Which scar, overall, appears to have improved more from initial to final visit, as rated by blinded examiner of photographs

Control Scar
n=8 BROW
Each patient had a scar which was randomized to not undergo treatments with Laser Genesis, and was used as a control. Patients were not allowed to undergo laser or any other scar treatments with the exception of sun protection for the control scar for the duration of the study.

SECONDARY outcome

Timeframe: 10 minutes before first treatment and at the final visit

Population: Patients were asked to grade overall cosmesis of both the treated and control scars on a 1-10 scale, with 1 being extremely poor and 10 being extremely excellent. Grading was done 10 minutes prior to each laser treatment and 4 weeks after final treatment

Subjects were asked to rate overall cosmesis of both the treated and control scars on a 1-10 scale, with 1 being extremely poor and 10 being extremely excellent, as rated by participant

SECONDARY outcome

Timeframe: within 1 hour after final treatment

Population: Within 1 hour after treatment, subjects were given a mirror and asked to rate perceived hair loss for each side on a 1-10 scale, with 1 representing none and 10 representing very significant

After each laser session, subjects were asked to rate perceived amount of hair loss from both the treated and control scars on a 1-10 scale, with 1 being none at all and 10 being extremely significant
