New age of cosmetology procedures with picosecond lasers

Abstract

Picosecond laser technology stands as one of the most advanced and promising tools in dermatology and aesthetic medicine, enabling precise and targeted treatment of various skin layers with minimal thermal impact and short recovery times. The first section of this article provides a detailed overview of the physical characteristics of picosecond lasers, with particular emphasis on phenomena such as Laser-Induced Optical Breakdown (LIOB) and Diffractive Optical Elements (DOE), which play crucial roles in the tissue interaction mechanisms of laser energy. Subsequently, we examine the indications for picosecond lasers within cosmetic practice, including the treatment of epidermal and dermal pigmented lesions, surgical scars, as well as skin rejuvenation and wrinkle reduction. In the concluding part of the article, we present case studies demonstrating the practical applications of picosecond laser treatments, highlighting the advantages of the PicoSculptur® method and the differences in treatment approaches between male and female facial skin. The aim of this summary is to provide a comprehensive overview of the role and power of picosecond lasers in modern cosmetic practice, emphasizing the technology's precision, versatility, and the benefits it offers to patients.
