Applications of Long-Pulse Alexandrite Laser in Cosmetic Dermatology: A Review

Changhan Chen et al. Clin Cosmet Investig Dermatol. .

Abstract

The long-pulse alexandrite laser uses Cr3+:BeAl2O4 crystals as the activation medium and has a 755nm wavelength and millisecond pulse duration. The long-pulse alexandrite laser has been utilized for hair removal, vascular lesions, pigmented lesions, and other conditions because melanin and hemoglobin in the skin, subcutaneous tissues, and skin appendages can specifically absorb this type of laser. To serve as a guide and source of inspiration for the clinical use of this type of laser, we review the present research status and advancement of the long-pulse alexandrite laser in the treatment of the aforementioned categories of disorders.

Keywords: hair removal; long-pulse alexandrite laser; pigmented lesions; vascular lesions.
