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 growing credibility. Thirdly, it proposes mechanistic differences in light delivery regimes and the resulting divergences in mode of action. Materials and Methods An 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. 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. Results 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. Clearly, HUDs are different compared to professional systems both in terms of fluence per pulse and in terms of biological mechanisms underlying hair removal. 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. Catagen transition was characterized by morphological changes similar to what occurs in vivo with occasional detection of apoptosis in the dermal papilla and outer root sheath cells. This suggests that high hair reduction can be expected in vivo and longer‐term treatment might result in HF miniaturization due to a cumulative effect on the dermal papilla and outer root sheath cells. In line with this hypothesis, in this review we demonstrate that long‐term application of a commercially‐available home‐use IPL appliance resulted in persistent hair reduction (80%) one year after last treatment. These data are in line with what was previously reported in the literature, where clinical studies with home‐use IPL appliances demonstrated high efficacy of hair reduction on female legs, armpits and bikini zones, with full hair regrowth after four treatments following cessation of IPL administration. Limitations of HUDs include lack of hair clearance for very dark skin types and low speed of treatment compared with professional devices. Numerous uncontrolled and controlled clinical efficacy studies and technical safety investigations on consumer‐use appliances support many of the leading manufacturers' claims. Analysis & Conclusions Manufacturers make consumer appliances safe and easy to use by considering “human factors,” needs and capabilities of a variety of users. Safety is of primary concern to manufacturers, regulators and standards bodies as these appliances may be accessible to children or their use attempted on uns...

The safety of 4 weeks' continuous use of NEWA TM , a high-frequency facial treatment appliance, every alternate day at home was verified, and its efficacy was evaluated in Japanese individuals with healthy skin aged 30 years or older who complained of sagging of the facial skin. Transepidermal water loss (TEWL), melanin levels, erythema levels, sebum secretion levels, skin color changes and wrinkle improvement in the facial skin were measured before the appliance began to be used (study baseline), at 2 and 4 weeks after it had begun to be used, and at 2 weeks after completion of the 4-week treatment period (6 weeks from the study baseline). In addition, data obtained by subjective evaluation by the subjects themselves on a visual analog scale (VAS) were also analyzed. Furthermore, skin biopsies were obtained from 3 subjects under local anesthesia with a 3-mm punch on two occasions, the first before the appliance began to be used and the second at 1 week after the 4-week treatment period (i.e., at 5 weeks from the study baseline), and the specimens obtained were stained with hematoxylin and eosin (HE) for light microscopy and subjected to immunohistochemical analysis for proliferating cell nuclear antigen (PCNA) and p53. There were no adverse reactions, and the treatment was effective for skin color changes and wrinkle improvement. The VAS results also showed improvement in the skin sagging. Histopathological examination revealed no marked changes in the epidermis and very mild lymphocytic infiltration in the upper dermis, mainly around the blood vessels and appendages. Immunohistochemistry revealed strongly positive staining for PCNA in the basal layer of the epidermis and positivity in almost all layers of the epidermis at 5 weeks from the study baseline. P53 staining was negative. The above results suggest the safety of NEWA TM , which was evaluated in this study, as a home-use appliance, and also its efficacy to some extent for improving the beauty of the facial skin without any downtime.

“…Although professional medical treatment still remains as the standard form of treatment, the home‐use device market is undoubtedly growing at an exponential rate because home‐use devices are gaining increasing popularity through social media and marketing 2 . However, insufficient amount of studies in home‐use devices is a major drawback, and a lack of knowledge and expertise in understanding the scientific mechanism of action by each technology as well as a lack of proper education could lead to false beliefs and confusions in the market 3 …”

“…2 However, insufficient amount of studies in home-use devices is a major drawback, and a lack of knowledge and expertise in understanding the scientific mechanism of action by each technology as well as a lack of proper education could lead to false beliefs and confusions in the market. 3 Hence, we have conducted a clinical study to evaluate and compare the safety and efficacy of using 660-and 850-nm home-use LED mask device in combination with hyaluronic acid (HA) ampoule or using HA ampoule alone on Asian subjects with photoaged skin and, therefore, to propose that 660-and 850-nm home-use LED mask device can generate synergistic effects and, thus, improve the appearance of photoaged skin when used along with topical applications such as HA.…”

Background Recently, light‐emitting diode (LED) devices are among those mostly preferred for esthetic application because they improve the appearance of photoaged skin characterized by wrinkles, sagginess, pigmented lesions, and others. In addition, the use of hyaluronic acid (HA) for skin rejuvenation is already well proven. Aims This study aims to evaluate the synergistic effects of using home‐use LED mask device with HA ampoule. Methods The total number of recruited subjects was 48:24 in Group A treated with both home‐use LED mask device and HA ampoule and 24 in Group B treated with HA ampoule only, for 4 weeks. To assess the efficacy of the treatment, the following were used: Antera 3D CS, EOS 800D with Image‐Pro Plus, DUB‐USB, VisioFace Quick, and Visioscan VC98. Results After treatment, the volume measurement (mm3) for prejowl sulci and nasolabial fold flattening as well as the area measurement (pixel) for lower chin firmness improvement was significantly reduced, and the number of pores (ea) for enlarged pores as well as the desquamation index (%) for the amount of corneocytes significantly decreased in both Group A and Group B. Moreover, the percentage of skin density significantly improved. Furthermore, Group A showed a significantly faster and higher rate of improvement than Group B. Conclusion The use of 660‐ and 850‐nm home‐use LED mask device can generate synergistic effects on home‐use topical applications like HA on photoaged face, and such device can be safely and efficiently used daily in personal environments.
