This review discusses the potential use of spin traps in cosmetic products to limit reactive oxygen species generated by pollution, emphasizing the need for further research due to toxicity and regulatory concerns.

This research describes using advanced mass spectrometry imaging techniques to analyze gunshot residue and map molecular components in biological samples, such as tumors and mosquito ovarian follicles, at unprecedented spatial resolution and specificity.

This review discusses the use of lasers and light sources for hair transplantation and pattern hair loss, noting past issues with CO2 lasers and suggesting further trials for low-level light laser therapy.

The ProScope HR is an effective, user-friendly, and affordable tool for diagnosing hair loss.

This article reviews the optimal methods for photographic documentation in managing patients with androgenetic or diffuse alopecia and reports no clinical results.

This study found that polymorphous light eruption (PLE) may include a wide range of conditions, requiring careful differentiation from similar skin disorders such as benign summer light eruption.

In this study, red-light irradiation significantly increased hair follicle numbers and ATP levels in a mouse model, highlighting low-level laser therapy's potential to enhance hair regeneration and alter the skin metabolic microenvironment.

This review discusses various methods of light-based hair removal and reports no new clinical results, highlighting advances in laser and intense pulsed light technologies used for targeting hair pigmentation.

This study observed nestin-GFP expressing stem cells in the hair follicle bulge of living mice using high-resolution in-vivo multiphoton tomography, allowing migration tracking within their natural skin environment.

This study reported that in men with androgenic alopecia, a distinct subclinical hyperpigmentation pattern was observed in the scalp, associated with baldness severity and possibly linked to local melanin production by pilosebaceous units.

This review discusses hormonal systems in the skin, such as the hypothalamic-pituitary-adrenal and hypothalamic-pituitary-thyroid axes, and reports no new clinical results.

Scientists made glow-in-the-dark dots from human hair that can detect iron, prevent counterfeiting, and reveal fingerprints.

This review highlights that two-photon excitation microscopy is a valuable tool for visualizing live skin structures and immune responses at high resolution, though its clinical use is hindered by safety and cost issues.

This systematic review found that licensed hair gloss products in the UK provide significant cosmetic benefits like improved shine and smoothness, but 18% contain harmful additives, highlighting the need for stricter regulations and patient education on product safety.

In a randomized clinical trial, Robinson et al found that patients with melanoma and their partners could effectively perform skin self-examinations after participating in a 30-minute structured skills training, potentially aiding early detection of additional melanomas.

This study evaluated a new high-power, 810 nm diode laser for hair removal, finding it to be effective and safe, with a mean hair reduction of 74.4% in one session, and noted it worked efficiently on both large and small areas with minimal side effects.

This study analyzed clinical and histological reports and concluded that blue light therapy is safe for human skin, with potential photoprotective effects against UV irradiation due to its impact on skin pigmentation mediated by Opsin-3.

This review discusses applications of light diffraction in healthcare, highlighting its use in LASIK procedures, optogenetics, and measuring hair diameter, but reports no new results.

This study found that a combination of dermatoscopy and reflectance confocal microscopy assists in accurately diagnosing pigmented prurigo, which is often misdiagnosed due to its varied clinical manifestations.

This case report describes a strong dermoscopic and histopathological correlation in lichen nitidus, helping differentiate it from other similar conditions.

The conclusion is that a new method to measure hair shine was confirmed to match people's visual assessments.

This study found that in a mouse model of Focal Dermal Hypoplasia, treatment with lithium carbonate improved skin disease symptoms compared to controls, though disease severity varied and posed interpretation challenges.

In this study, three patients with alopecia areata exhibited spotty absence of the whiteness of their nail lunulae, potentially due to defects in the matrical epithelium.

This study found that pulsed diode laser treatment safely and effectively cleared lesions and reduced the appearance of dark plugs in trichostasis spinulosa for up to 20 weeks in dark-skinned individuals.

This review summarizes late-breaking abstracts from the American Society for Laser Medicine and Surgery, 2018, and reports no new clinical findings.

This review discusses the applications of the 308-nm excimer laser in treating various dermatologic conditions and suggests treatment is generally well tolerated, but calls for larger long-term studies.
