Here we presented data showing that a single low fluence pulse of both 810 nm laser (6.6 J/cm², 16 ms) and IPL (9 J/cm², 15 ms and 6.8 J/cm², 1.9 ms) leads to induction of catagen transition.

Clearly, HUDs are different compared to professional systems both in terms of fluence per pulse and in terms of biological mechanisms underlying hair removal. Significant basic science and clinical evidence has been published to confirm the clinical efficacy and technical safety of many laser and IPL home‐use devices for hair removal. Establishing the likely biological mode of action of professional high‐fluence systems versus home‐use low‐fluence appliances was performed by combining data obtained using ex vivo hair follicle (HF) organ culture and the clinical results involving human participants. Thirdly, it proposes mechanistic differences in light delivery regimes and the resulting divergences in mode of action.Īn extensive literature search was performed to review the progress of laser/IPL‐induced hair reduction and determine what evidence is available to explain the mode of action of professional and HUDs for hair removal. Secondly, it summarises published literature reviews on home‐use devices (HUDs) as evidence of their growing credibility. 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. The Home Skinovations brands Silk ’ n and SensEpil were found to be the same, and the Philips brands SatinLux and Lumea were also found to be the same in respect of all measurements made (Fig. All devices were purchased through major retailers to reflect product quality and performance being delivered to consumers. The devices evaluated in this report include: iPulse Personal (CyDen Ltd, Swansea, UK), Silk ’ n/SensEpil (Home Skinovations Ltd, Yokneam, Israel), and SatinLux/Lumea (Philips, Eindhoven, Netherlands). on the measurement of professional and home- use IPL systems. The measurement methods used in this investigation are those reported in previously published studies by Town and Ash et al.

The optical energy of suitable wavelengths is emitted and absorbed by melanin and other chromophores in the user ’ s skin within a time constant that heats the actively growing hair shaft and hair bulb to temperatures of 65 – 70☌ causing sufficient damage to the hair follicle to prevent its regrowth. A consumer IPL hair-removal system operates on the same principle of selective photothermolysis as professional IPL/laser systems. Nevertheless, however inexpensively these light-based systems are produced, they are designed to cause biological damage to follicular structures and precautions must be taken to prevent epidermal and ocular damage.

There is a market for a convenient and effective method of long-lasting epilation using light with a number of FMCG corporations looking to enter this new sector. Such devices can offer greater privacy and personal convenience to the consumer than professionally delivered hair-removal treatments and a reduction in cost of maintaining hair-free skin for extended periods. Technological challenges for such devices are that they have to be clinically effective while being eye-safe, easy to use without training, and most importantly for the manufacturer, cost-effective in mass production. Over the past decade, several companies have been exploring simple low-energy home-use devices and such systems are usually limited to a few energy settings, fixed pulse duration, single fixed filter, small treatment areas without any option for parallel skin cooling and covering fewer skin tones compared to professional systems.

hair-removal industry is reportedly worth approximate- ly 10 billion US dollars annually and many companies are expected to launch new light-based devices for hair reduction within the next year following those who have already done so.
