Abstract
We have evaluated and compared the effectiveness of diode laser system (808 nm) and Intense Pulse Light (IPL) system (690 - 1200 nm) by studying the change in hair density, and the time of regrowth the hair. A total of 26 have completed three months’ treatment, aged 16 - 50 years. Patients were treated by diode laser 808 nm and IPL 690 - 1200 nm devices. Pulse repetition rate for both was 1 Hz and short pulse width for diode laser and the IPL pulse width was 15 ms. The fluence was (33 - 41 and 30 - 41) J/cm2 respectively. A split face treatment method was used. The treatment was carried out on monthly bases for three months. Hair density and regrowth duration were recorded before and after each session. After the third session, the hair density was decreased by (58%) for diode laser versus (49%) for IPL p = 0.366. The time of hair regrowth was increased to (327%) for diode laser versus IPL (339%) p = 0.821. Pain appeared more during the treatment with IPL than with diode laser. Post treatment side effects such as erythema, hyper pigmentation, and burn appeared on patients treated with diode laser more than those treated with IPL. In conclusion both diode laser and IPL were effective in reduction of hair density, and prolongation of the time of hair regrowth.
Highlights
Materials and MethodsThe study conducted at a private clinic in Al-Karrada district, Baghdad, Iraq in the period from January to November in 2013
For diode laser it decreased by 30%, 45% and 58% after the first, second, and third session, respectively compared with Intense Pulse Light (IPL) in which the hair density was decreased by 38%, 44% and 49% after the first, second, and third, respectively Table 1
In contrast the number of patients felling pain is significantly higher with IPL (27) treatment than those treated with diode laser (19), while side effect of swelling is the same (3, 3) and for erythema is about the same except the difference in the second session Table 3
Summary
The study conducted at a private clinic in Al-Karrada district, Baghdad, Iraq in the period from January to November in 2013. A total of 26 patients participated in the study and completed three month treatments. Their age ranged between 16 - 50 years with (average ± SD) 29.95 ± 8.05 years. The device was set as short pulse (3.2 ms), pulse rate (1 Hz) and the fluence range from (33 - 41 J/ cm). After treating the right side of the face, the patient was moved to the IPL device and the left side was treated in the same manner Figure 1. Ice cold gel was used before and after treatment completion for about 10 minutes. All the patients were evaluated before the treatment and at each visit; the following observations were recorded:
