VSP (Variable Square Pulse) Nd:YAG laser devices hold the most prominent position among all available laser sources for hair removal. This is due to the long wavelength (1064 nm) which Nd:YAG devices produce. Light with a wavelength of 1064 nm lies in a biological absorption region that allows light to penetrate deep into the skin, but at the same time its absorption in hair follicles is strong...

The main goal of our work is initial preprocessing of dermoscopic images by hair removal. Dermoscopy is a basic technique in skin melanoma diagnostics. One of the main problems in dermoscopy images analysis are hairs objects in the image. Hairs partially shade the main region of interest that’s why it needs special treatment. We have developed a simple and fast hair removal algorithm based on b...

BACKGROUND AND OBJECTIVE In recent years, selective photothermolysis (PT) based on broadband light and assisted by skin vacuum (Photopneumatic Technology or PPx, by Aesthera) was introduced into the aesthetic market for epilation (hair removal) procedures. The present study aims to: (a) determine the overall effect of PPx on skin humidity and associated skin optical properties, and; (b) develop...

Male grooming has its roots in antiquity. Control and styling of facial hair has invariably required the development and use of metal instrumentation. Once crude and unreliable, it has latterly become sophisticated and subject to intense research and development at the highest scientific level. This paper describes how male grooming is being impacted by improvements in fundamental understanding...

BACKGROUND Using the concept of selective photothermolysis, a variety of laser systems have been developed to remove unwanted hair. OBJECTIVE To evaluate the relative efficacy, tolerability, and subject satisfaction of three different laser systems used individually and in rotation for axillary hair removal. METHODS Twenty female patients (17 with dark-colored hair, 3 with red or light-colo...

BACKGROUND AND OBJECTIVE Recently, the first diode laser with a wavelength of 755 nm for in-motion hair removal came on the market. The objective of this study was to check its efficacy, safety, and practicality under different options for its use. METHODS A prospective study in a heterogeneous group of 56 patients who had hair removed from various areas of their bodies using three different ...

OBJECTIVE To investigate the possible stimulating mechanism of Huoxue Bushen Mixture (HXBSM), a traditional Chinese compound medicine, on hair growth of mice via measuring the variance of skin blood vessel neogenesis and vascular endothelial growth factor (VEGF) expression in the hair follicle. METHODS Hot rosin and paraffin mixture depilation were used to induce C57BL/6 mice hair follicle to...

Although a variety of lasers have proven to be clinically effective for long-term hair removal, the use of these lasers has also been associated with undesirable side effects, such as hyper- and hypopigmentation, crusting, erythema, and edema. One notable side effect that seems to be underreported in the literature is the growth of fine dark hair in untreated areas close to the treated ones. Th...

BACKGROUND Although there are several different laser systems available for the reduction of unwanted hair, no single system has been shown to be superior in providing safe and effective hair removal in every skin type. The purpose of this study was to evaluate the safety and efficacy of a high-energy, long-pulsed, 1064-nm Nd:YAG laser with a contact cooling device for hair removal in skin phot...
