EN ESTE ESTUDIO SE COMPARA UN LASER DE DIODO, DE 810 NM POR DISPARO, COMO EL LIGHTSHEER, Y EL LASER DE DIODO DE 810 NM CON EL METODO DE BAJA FLUENCIA EN MOVIMIENTO, COMO EL SOPRANO. CON AMBOS OBTIENEN RESULTADOS PARECIDOS EN AMBOS EN LA MEDICION A LOS 6 MESES Y A LOS 18 MESES. LO SORPRENDENTE FUE ENCONTRAR QUE LOS RESULTADOS FUERON MEJORES EN LA SEGUNDA MEDICION COMPARADO CON LA PRIMERA. ADJUDICAN ESTO AL EFECTO DEL LASER SOBRE LOS VELLOS EN TELOGENO! SORPRENDENTE!
LOW FLUENCE MULTIPLE PASS vs HIGH FLUENCE SINGLE PASS DIODE LASER HAIR REMOVAL – TWO YEARS POST TREATMENT MARTIN BRAUN, M.D. Vancouver, Canada
.All of the traditional laser systems used the highest fluence possible without damaging the tissue surrounding the hair follicle with a single pass.
A diode laser with low level fluence (5-10 J/cm2) with a high repetition rate at 10 Hz (Soprano SHR by Alma Lasers, Chicago) using multiple passes in constant motion technique was compared to traditional one pass high fluence (25-40 J/cm2) diode laser (Lightsheer ET, Lumenis, Santa Clara)
Both the low fluence, multiple pass and high fluence, single pass diode lasers performed very well with hair reduction counts exceeding 80% following the 5th and final laser treatment. We were surprised to see that the 18 month hair counts were even better than the 6 month hair counts. It appears that the amount of hair reduction achieved at 6 months following the final laser treatment is permanent, as it correlates very well with the 18 month hair counts.
The difference in pain scores was highly significant, with the low fluence, multiple pass technique being much more comfortable. This result is not unexpected, as the low fluence diode pulses were 10 J/cm2 verses 20-50 J/cm2 using the single pass diode laser.
Patients were asked the question, “Which laser is less painful?” on their final treatment, and 92% chose the low fluence, multiple pass technique (Soprano ) laser.-
