Photoepilation

Atypical clinical and dermoscopic findings, or changes in pigmented melanocytic lesions located on body areas treated with lasers or intense pulsed light (IPL) for hair removal (photoepilation), have been described in the literature. There are three prospective studies in a total of 79 individuals with 287 melanocytic nevi and several case reports reporting the dermoscopic findings and changes after photoepilation. Clinical changes have been reported in 20-100% of individuals, while dermoscopic changes have been observed in 48% to 93% of nevi...

This article introduces the safety risks of the novel light-based home-use hair removal device, and analyzes the differences in regulation among China, the United States and the European Union. In China, household intense pulsed light hair removal devices will also be supervised in accordance with medical device regulations. Therefore, the safety standards adopted in the absence of specific regulations are no longer applicable to the new regulatory requirements. It is imperative to adopt the new standards available to home photoepilators, so as to ensure the safety and effectiveness of the approved devices...

BACKGROUND: Changes in the appearance of melanocytic nevi have been increasingly reported following hair removal lasers. This could be a source of anxiety in patients doing cosmetic hair removal lasers. Moreover, taking biopsy of any changed nevus following laser is not routinely practical. Therefore, this study was designed to describe dermoscopic changes happened on acquired junctional melanocytic nevi after photo-depilation methods. METHOD: In this prospective study, 66 melanocytic nevi in 27 patients were chosen...

BACKGROUND: Photoepilation by a single-wavelength laser device is being commonly used for hair removal. Whether emitting multiple laser wavelengths to induce hair unit damage would be beneficial is yet to be established. OBJECTIVE: To evaluate the safety and efficacy of hair reduction using a novel simultaneous multi-wavelength laser device. PATIENTS AND METHODS: A retrospective cohort study was carried out among adult males. Hairy sites were treated by a simultaneous triple-wavelength (755nm, 810nm and 1064nm) laser device (Soprano Titanium...

Unwanted hair growth, which is a common aesthetic problem, has traditionally been treated using various techniques such as shaving, waxing, and epilation, but most of these provide only a temporary solution. Laser and light-based technology for hair removal has become one of the fastest growing procedures in modern cosmetic dermatology in the last decade. Clinical experience suggests that in the ideal subject with fair skin and dark hair, laser treatment can reduce hair growth significantly. This article reviews the various laser and light-based devices used for hair removal along with the various laser and patient parameters that affect the outcome of laser treatment for hair removal...

AIMS: The purpose of our study was to compare a IPL device with an IPL plus RF in one device, using a within-patient, right-left controlled study design. PATIENTS/METHODS: Thirty-three patients completed four treatment sessions and the follow-up period of the study...

Using light sources in phototherapy has presented promising results regarding several types of facial and body skin affections for centuries. The neodymium-doped yttrium aluminum garnet (ND:YAG) 1064 nm laser has become a standard treatment in dermatology for dermatological disturbances related to the pilous follicle and the structures surrounding it. Despite the reports of its clinical benefits, few scientific studies show its actual safety and efficacy. To substantiate the effects, benefits, and safety of applying an ND:YAG 1064 laser in the epilation process during esthetic treatment, a systematic review was carried out between October 2018 and January 2019, on studies published in the last 20 years...

Hirsutism is the excessive growth of terminal hair in a typical male pattern in a female. It is often a sign of excessive androgen levels. Although many conditions can lead to hirsutism, polycystic ovary syndrome and idiopathic hyperandrogenism account for more than 85% of cases. Less common causes include idiopathic hirsutism, nonclassic congenital adrenal hyperplasia, androgen-secreting tumors, medications, hyperprolactinemia, thyroid disorders, and Cushing syndrome. Women with an abnormal hirsutism score based on the Ferriman-Gallwey scoring system should be evaluated for elevated androgen levels...

OBJECTIVES: Photoepilation is a commonly used technology in home-use devices (HUDs) and in professional systems to remove unwanted body hair using pulses of laser or intense pulsed light (IPL). Albeit HUDs and professional systems operate at different fluences and treatment regimes, both demonstrate high hair reduction. The underlying mechanisms, however, remain unknown partly due to high divergence of the existing literature data. The objective of this study was to develop an ex vivo photoepilation model with a set of criteria evaluating response to light pulses; and to investigate dose-response behavior of hair follicles (HFs) subjected to a range of fluences...

OBJECTIVE: To update the "Evaluation and Treatment of Hirsutism in Premenopausal Women: An Endocrine Society Clinical Practice Guideline," published by the Endocrine Society in 2008. PARTICIPANTS: The participants include an Endocrine Society-appointed task force of seven medical experts and a methodologist. EVIDENCE: This evidence-based guideline was developed using the Grading of Recommendations, Assessment, Development, and Evaluation system to describe the strength of recommendations and the quality of evidence...

The High Power Pulsed Light™ [HPPL™] and Incoherent Fast Light™ technologies [IFL™, Novavision Group S.p.A., 20826 Misinto (MB), Italy] are recent innovations in the field of unwanted hair removal with intense pulsed light devices. IFL™ is a further improvement over the already advanced characteristics of the HPPL™ technology. A selection of photoepilation case histories with the HPPL™ and IFL™ technologies is presented; a short introduction highlights the main features of the two technologies...

The effectiveness of intense pulsed light (IPL) and laser devices is widely accepted in aesthetic dermatology for unwanted hair removal and treatment of a variety of cutaneous conditions. Overall, most comparative trials have demonstrated similar effectiveness for IPL and laser devices. Literature studies alternatively favor the IPL and laser concepts, but the incidence of severe local pain and side effects were generally lower with IPL. IPL phototherapy, already established as a sound option in photoepilation and treatment of photoaging, hyperpigmentation and other skin conditions, is also considered first choice in the phototherapy of skin vascular malformations...

Laser-based photoepilation of dark skin types demands a delicate combination of appropriate light wavelengths and spot size to achieve optimal epidermal-to-follicular energy absorption ratios. This prospective study assessed the axillary, arm, thigh, and back hair clearing ef cacy of the LightSheer In nity 1060 nm diode laser in 10 Fitzpatrick skin type IV-V patients. Each area was treated up to ve times, at 4-6-week intervals, after which immediate skin responses and adverse events were recorded. Hair count, color and coarseness were assessed before each treatment session, as well as 1, 3, and 6 months following the last session...

BACKGROUND AND OBJECTIVES: There are no large volume comparative studies available to compare the efficacy of lasers over lights for hair removal in Fitzpatrick V and VI skin types. This study is designed to compare the efficacy of Nd:YAG laser versus IPL in the darker skin types. STUDY DESIGN/MATERIALS AND METHODS: Thirty-nine patients included in Group-1 were treated with Nd:YAG and 31 in Group-2 with IPL. Both groups received 5 sessions of treatment. The hair counts were assessed using digital photography and manual counting method before and after treatment and the results were analysed...

BACKGROUND: Photothermolysis of unwanted hair depends on the presence of melanin in the hair follicle as the chromophore, but is not effective in patients with non-pigmented, melanin-sparse hair shafts and follicles. This split-scalp, double-blind study was to monitor the efficacy of melanin bound in nanosomes to inject exogenous melanin into the hair follicles thus potentiating successful photothermolysis.<br /> MATERIAL AND METHODS: Twelve patients, phototypes II-III, with white or very fair hair, were treated with a compound containing melanin encapsulated in nanosomes (Melaser^®) together with a fluorescent marker...
