Abstract
Background Lasers permit treatment of unwanted excess hair with less discomfort than other methods of epilation. Many lasers with different parameters are now available from which the dermatologist can choose. Improved clinical results are made possible by the high specificity and selectivity of the laser systems to pigmented hair because of the use of an appropriate wavelength with the proper pulse and duration.
Objectives We aimed to compare the results of treatment of skin types IV, V, and VI using three different laser systems.
Methods One hundred female patients were compared using different laser systems: 35 patients underwent epilation using a NdโYag laser, 33 patients using an Alexandrite laser, and 32 patients using a Diode laser.
Results Follow up 12ย months after the multiple treatments (three to six sessions) showed an insignificant difference between these three groups (35โ40%).
Conclusion Our findings indicate that all three laser systems tested can be used for dark skin; however, one should select a system that minimizes sideโeffects, primarily hypoโ and hyperโpigmentation, especially when used for skin types IV, V, and VI.
