Highlighting nuances of blue light phototherapy: �mechanisms, safety & benefits considerations
Article
Full-text available
The efficacy of blue light therapy in dermatology relies on numerous clinical studies. The safety remains to be a topic of controversy, where potentially deleterious effects were derived from in vitro rather than in vivo experiments. The objectives of this work were 1) to highlight the nuances behind ‘colors’ of blue light, light propagation in tis...
Article
Demand for long-term hair reduction treatments has increased dramatically around the world in recent years, due to traditional factors, fashion, sport, wellbeing and health requirements. Some of the most popular options include laser and intense pulsed light (IPL) treatments, which are often administered by aesthetic practitioners. This article wil...
Article
Objectives This review has the following objectives: Firstly, it provides an explanation of the evolution of laser/intense pulsed light (IPL) hair reduction modalities from high fluence professional devices to low fluence home‐use appliances. Secondly, it summarises published literature reviews on home‐use devices (HUDs) as evidence of their growin...
Article
Full-text available
The development and use of light and lasers for medical and cosmetic procedures has increased exponentially over the past decade. This review article focuses on the incidence of reported cases of skin cancer post laser or IPL treatment. The existing evidence base of over 25 years of laser and IPL use to date has not raised any concerns regarding it...
Article
Introduction & Objectives This qualitative review of paradoxical hair growth following professional treatments reviews clarifies whether low fluence is the most probable cause of unwanted hair regrowth following at home light-based treatments.Materials & Methods The proposed causes of unexpected hair regrowth are examined and our scientific underst...
Article
Full-text available
To evaluate a novel skin tone meter (STM) to categorize skin tones into one of the six categories of the Fitzpatrick skin type (FST) classification system, thus optimizing safety in light-based dermatological procedures. This numerical classification method measures several components; principally the reaction of human skin to ultraviolet (UV) ligh...
Article
Full-text available
Background and objective: This study considers end point tissue responses and side effects to determine whether 'square pulse' IPL is more or less effective than the traditional IPL. Supporting histological data and computational modelling results are provided. It provides guidance for IPL users unfamiliar with constant spectrum IPL devices and re...
Article
Background: The aim of this study is to investigate the cellular mechanism of long-term hair reduction using a novel, square pulse, low-fluence home-use IPL device. Methods: Ten subjects' axillae (Fitzpatrick III-V) were treated once weekly for four consecutive weeks in a simulated home-use trial. Treated and control site punch biopsies were tak...
Article
The recent development of light-based laser and intense light devices for consumer use with or without physician direction has raised new challenges in safety standards and regulatory requirements for these appliances. Home-use laser products have emission levels from "embedded" lasers that would ordinarily result in their having laser hazard class...

Article
Full-text available
The objective of this work is the investigation of intense pulsed light (IPL) photoepilation using Monte Carlo simulation to model the effect of the output dosimetry with millisecond exposure used by typical commercial IPL systems. The temporal pulse shape is an important parameter, which may affect the biological tissue response in terms of effica...
Article
In the past 5 years since their US introduction, there has been a rapid proliferation of light-based hair removal devices intended for home-use. In the last 2 years in Europe, sales already run into many tens of thousands of units with well-known multi-national companies entering the market. These guidelines provide a definition of light-based home...
Article
Hair removal with professional light-based devices is established as an effective, mainstream treatment. The field of optical home-based hair removal is evolving and movement from control by physicians into hands of consumers warrants understanding efficacy and human safety. To systematically review and evaluate the efficacy and human safety of cur...

The current annual global market for domestic intense pulse light (IPL) hair removal has been estimated at US $1 billion and continues to grow. The five key technological parameters to consider in cutaneous photo-therapy are wavelength, energy density, pulse duration, spot size and spatial distribution. Uneven energy distribution in the treatment a...
Article
Full-text available
The domestic market for home-use hair removal devices is rapidly expanding and there are numerous intense pulsed light (IPL) products now available globally to consumers. Technological challenges for the design of such devices include the need to be cost-effective in mass production, easy to use without training, and most importantly, clinically ef...
Article
Home-use light based treatments have been documented since 2003 and a number of home-use devices for hair removal and skin rejuvenation have been launched recently in Europe. Several safety and efficacy studies have also appeared in international journals confirming meaningful hair reduction figures and relatively few side effects but some are stil...

High quality intense pulsed light (IPL) systems can offer simple, safe and effective treatments for long-term hair reduction, skin rejuvenation and removal of benign vascular and pigmented lesions. Considerable differences in clinical efficacy and adverse effects have been recorded amongst different IPL systems despite comparable display settings....
Article
Full-text available
Laser and intense pulsed light (IPL) devices are used routinely by healthcare professionals for hair removal, but laser and light technology devices intended for home use have so far had little impact in the consumer market. However, as multinational companies enter this market, there will be an explosion in the use of such devices by the consumer....

To evaluate the reduction in unwanted body and facial hair at various body sites of Fitzpatrick skin types I-III and the efficacy, comfort and safety of this treatment intended for home-use by the general public. In this non-randomized study, 29 individuals were given three sequential weekly treatments on a total of 31 body and facial areas includi...
Article
High quality IPLs can offer simple, safe and effective treatments for long-term hair removal, removal of benign vascular and pigmented skin abnormalities, skin rejuvenation and acne treatments. Significant differences in clinical outcome have been recorded among different free-discharge and constant current IPLs despite identical settings. We inves...

Laser therapy has been very common since 15 years before and laser therapy has revealed markedly effective for not only birth marks but common skin disorders: acne, verruca and so on. Lasers are very safe instruments with adequate precautions. However, lasers need high voltage, and they can cause fire or ocular hazards. Lasers should be used carefu...
