Images of flawless skin, sculpted features, and curated aesthetics inundate user feeds, potentially shaping their self-perceptions and aspirations. The rise of influencers, dermatologist social media engagement, and beauty campaigns sharing skincare routines and product recommendations wield substantial influence over individual appearance-related decisions. AIMS: The main aim of this study is to determine the pattern of behavior in using social media to seek dermatological procedures and skin care routine...

BACKGROUND: Skin photoaging and uneven pigmentation are common dermatological concerns. Tetrahexyldecyl ascorbate (THDA) and acetyl zingerone (AZ) are potent antioxidants that have been shown to have anti-photoaging and anti-pigmentation effects. THDA is a more stable and penetrable form of vitamin C. AZ is an antioxidant derived from ginger which has clinical evidence for improving photoaging. However, no studies have assessed how they may synergistically act on the skin. AIMS: This study aims to assess whether a serum containing both THDA and AZ can improve photoaging and the appearance of uneven facial pigmentation...

IMPORTANCE: Early treatment of port-wine birthmark (PWB) can be life-altering and is often associated with improved outcomes and quality of life. There is growing evidence that shorter treatment intervals may play a role in more rapid PWB clearance; however, the optimal treatment interval has not been established. OBJECTIVE: To describe the outcomes of once-weekly pulsed dye laser (PDL) treatments for PWB in infants. DESIGN, SETTING, AND PARTICIPANTS: This case series analyzed the medical records of patients with PWB who received once-weekly PDL treatments between January 1, 2022, and December 31, 2023, at the Laser & Skin Surgery Center of New York...

IMPORTANCE: Hirsutism represents a significant concern for women with polycystic ovary syndrome (PCOS), with deleterious psychological effects warranting acknowledgment and a clear imperative to provide effective management. To our knowledge, this is the first review to exclusively examine the effectiveness of laser and light-based therapies in addressing hirsutism in women with PCOS. OBJECTIVE: To synthesize the existing literature regarding the effectiveness of laser and light hair reduction therapies, either as stand-alone treatments or in combination with systemic agents, in treating hirsutism for women with PCOS...

The study aimed to explore the impact of a novel near-infrared LED (nNIR) with an extended spectrum on skin enhancement and hair growth. Various LED sources, including White and nNIRs, were compared across multiple parameters: cytotoxicity, adenosine triphosphate (ATP) synthesis, reactive oxygen species (ROS) reduction, skin thickness, collagen synthesis, collagenase expression, and hair follicle growth. Experiments were conducted on human skin cells and animal models. Cytotoxicity, ATP synthesis, and ROS reduction were evaluated in human skin cells exposed to nNIRs and Whites...

PURPOSE: The mainstay of treatment for nonmelanoma skin cancer (NMSC) on thin skin remains surgical, but procedures on older hands may be complicated by skin fragility and dermal atrophy. Used without cooling, 595 nm (nm) pulsed dye laser (PDL) has the capability of destroying NMSC through nonspecific thermal necrosis. The purpose of this study was to understand recurrence of NMSC on dorsal hands of older patients after one or two treatments using 595 nm PDL. METHODS: A retrospective chart review identified 147 cases of NMSC located on the dorsal hands treated with 595 nm PDL...

INTRODUCTION: The foot sole endures high magnitudes of pressure for sustained periods which results in transient but habitual cutaneous ischemia. Upon unloading, microvascular reactivity in cutaneous capillaries generates an influx of blood flow (PORH: post-occlusive reactive hyperemia). Whether pressure induced cutaneous ischemia from loading the foot sole impacts mechanoreceptor sensitivity remains unknown. METHODS: Pressure induced ischemia was attained using a custom-built-loading device that applied load to the whole right foot sole at 2 magnitudes (15 or 50% body weight), for 2 durations (2 or 10 minutes) in thirteen seated participants...

BACKGROUND: There is a dearth of effective treatments to counter retinol-induced skin irritation. OBJECTIVE: This study aimed to investigate the efficacy of three potential mitigants: (i) phytosteryl/octyldodecyl lauroyl glutamate (PLG), (ii) a physiologic lipid mixture (PLM) comprised of ceramide three and cholesterol, and (iii) niacinamide, in ameliorating irritation instigated by retinol. METHODS: An occlusive human patch test, spanning 5 days, was undertaken on 18 Chinese participants aged between 23 and 40...

Overly dense microvascular networks are treated by selective reduction of vascular elements. Inappropriate manipulation of microvessels could result in loss of host tissue function or a worsening of the clinical problem. Here, experimental, and computational models were developed to induce blood flow changes via selective artery and vein laser ablation and study the compensatory collateral flow redistribution and vessel diameter remodeling. The microvasculature was imaged non-invasively by bright-field and multi-photon laser microscopy, and optical coherence tomography pre-ablation and up to 30 days post-ablation...

BACKGROUND: Enoxolone, derived from licorice, possesses potent anti-inflammatory, and antioxidant properties. However, its effectiveness in alleviating post-laser reactions has not been extensively studied. AIMS: This randomized split-face pilot study aimed to evaluate the effects of enoxolone on skin following laser treatment. PATIENTS/METHODS: Ten healthy subjects underwent non-ablative 1550 nm Er:Glass fractional laser treatment and then randomly applied a moisturizer without enoxolone on one side of the face and a dermo-cosmetic formular containing 2% enoxolone mixed with the same moisturizer on the other side...

INTRODUCTION: Despite their role being historically overlooked, environmental surfaces have been shown to play a key role in the transmission of pathogens causative of healthcare-associated infections (HCAI). To guide infection prevention and control (IPC) interventions and inform clinical risk assessments, more needs to be known about microbial surface bioburden. AIMS: To identify the trends in culturable bacterial contamination across communal touch sites over time in a hospital setting...
