The picosecond lasers have shown to effectively treat tattoo pigments that are intractable to previous multiple Q-switched (QS) laser treatments. Therefore we hypothesized that a picosecond laser would show better efficacy with minimal adverse events in the treatment of melasma and post-inflammatory hyperpigmentation (PIH) that are difficult to treat with conventional QS lasers. Two patients wi...

682 infrared range of the electromagnetic spectrum. Though all these lasers would have some effect on melanin, three wavelength bands are most useful for treating pigmented lesions – green, red, and infrared.[1] Its not only about the wavelength, it is more about the right pulse duration and at sufficient fluence. Since green and blue light lasers are long pulsed continuous waves, they cause a ...

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 6...

INTRODUCTION To improve laser hair removal (LHR) for dark skin, the fluence rate reaching the hair follicle in LHR is important. This paper presents the results of a comparative study examining the function of wavelength on dark skin types using 755 nm alexandrite and 810 nm diode lasers. METHODS The structure of the skin was created using a realistic skin model by the Advanced Systems Analys...

BACKGROUND Alexandrite (755 nm) and diode lasers (800-810 nm) are commonly used for hair removal. The alexandrite laser technology is somewhat cumbersome whereas new diode lasers are more robust. Recently, alexandrite-like 755 nm wavelength diodes became available. OBJECTIVES To compare the efficacy, tolerability, and subject satisfaction of a 755 nm diode laser operated in conventional (HR) ...

Background: Laser treatment is a rapid, non-invasive procedure for long-term hair removal. Lasers operate based on the principle of selective photothermolysis and target melanin in the hair follicle. We intend to determine the level of hirsute patient satisfaction with the alexandrite laser hair removal procedure.Methods: In this cross-sectional study 82 hirsute patient...

OBJECTIVE To analyze variables affecting the treatment course and prognosis of Q-switched laser tattoo removal. DESIGN Observational prospective cohort study. SETTING The study was carried out in a referral center for surgery and laser surgery in Milan. PARTICIPANTS Of 397 consecutive patients initially enrolled from January 1, 1995, to December 31, 2010, 352 patients (201 men and 151 women; me...
