Efficacy of Lasers on Pigmentary Lesions

Our purpose is to study the efficacy of the alexandrite laser (755 nm) and the fractional laser when treating pigmentary lesions .We use the data of our private office of the last five years (2011-2015) We treated 1000 patients with freckles with alexandrite laser, 200 patients with melasma with fractional laser, 100 patients with post inflammatory hyperpigmentation with alexandrite laser and 60 patients with post inflammatory hyperpigmentation with fractional laser. We also studied the side effects of the therapies. Alexandrite laser has excellent results for freckles, while the combination of chemical peelings and fractional laser is good for the treatment of melasma. Post inflammatory hyperpigmentation has an intermediate response. The recurrence rates are higher in melasma and the side effects are generally minimal.
