Male facial rejuvenation using a combination 633, 830, and 1072 nm LED face mask.

Home-based photobiomodulation is a popular treatment modality for patients seeking non-invasive aesthetic treatment. Studies demonstrate that photobiomodulation is effective for skin rejuvenation, which is aimed at improving the overall appearance of the skin by reducing fine lines and wrinkles and improving skin texture, skin tone, and dyspigmentation. Most current skin rejuvenation research focuses on treatments in women. However, men's aesthetics remains an underserved market. A combined red light (RL) and near-infrared (NIR) light-emitting diode (LED) has been designed specifically to target male skin, which may have different physiological and biophysical properties compared to female skin. Herein, the safety and efficacy of a commercially available RL and NIR (633, 830, and 1072 nm) LED array designed to be worn as a face mask was assessed. Primary outcomes included adverse events and facial rejuvenation as determined by participant-reported satisfaction scales and quantitative digital skin photography and computer analysis after 6 weeks of treatment. The participants reported overall favorable results and improvements in all individual categories, were satisfied with the treatment, and would recommend the product to others. The participants perceived the greatest improvement in fine lines and wrinkles, skin texture, and youthful appearance. Photographic digital analysis demonstrated favorable improvements in wrinkles, UV spots, brown spots, pores, and porphyrins. These results support the use of RL and NIR to treat male skin. Advantages of the LED facemask include its safety, efficacy, convenient home-based use, minimal associated downtime, simple operation, non-invasiveness, and appreciable results in as few as 6 weeks.

Ultraviolet imaging in dermatology.

Visual examination plays a central role in the diagnosis of skin diseases. Many dermatologists use magnification, or dermoscopy, to improve diagnostic certainty when assessing the skin under visible light. In addition to magnification, other technological advances have been made over the last century to improve our visual assessment of the skin. Examination of skin under ultraviolet (UV) radiation, with Wood's light, gained traction for its utility in assessing superficial cutaneous infections and pigmentary changes. During Wood's light examination, UV light is directed at the skin and fluorescence is detected by our eyes. The variable fluorescent characteristics of endogenous and exogenous cutaneous chromophores help us better diagnose skin disease. UV fluorescent photography is based on the same concept as the Wood's light, but also allows image analysis and documentation of the captured image. In addition to UV-induced fluorescence, the differential reflection and absorption of UV light captured in the UV spectral range can also provide a new contrast for diagnosing skin diseases during UV reflectance photography. This review discusses the most widely used UV imaging techniques and provides an overview of the role of UV imaging in dermatology.

Erythema Gyratum Repens in Long-Term Smoker.

Erythema gyratum repens (EGR) is a rare paraneoplastic skin condition characterized by the eruption of expanding, concentric, erythematous patches and plaques. The condition may precede a symptomatic appearance of internal malignancy, and therefore provides a unique opportunity to prevent additional morbidity and mortality secondary to undetectable cancer growth. We report the case of a 71-year-old female patient clinically diagnosed with EGR and subsequently diagnosed with otherwise asymptomatic adenocarcinoma of the lung.
