Radiofrequency devices effectively tighten skin without surgery.

This review discusses the current evidence and highlights gaps in research needed for the wider acceptance of low-level laser therapy as a treatment for hair loss; no new clinical results are provided.

In this case report, the authors linked acute psoriasiform contact dermatitis of the forehead and scalp to a low-laser light cap, identifying DMDE in the fabric as a likely cause.

This review of low-level laser therapy for patterned hair loss found that red-spectrum light may be effective for hair growth, but larger case-controlled studies are needed to further support this conclusion.

This paper introduces an algorithm for using smart device-mounted microscopes to analyze scalp images and diagnose hair loss by extracting specific hair loss features.

The authors concluded that utilizing clock gene expression from hair follicle cells may improve circadian-phase estimation in clinical settings, aiding the detection of circadian-related sleep problems despite social time constraints.

This review highlights that laser and light treatments could serve as safe and effective alternatives to current therapies for alopecia areata, with the excimer laser showing positive results, though further randomized controlled trials are necessary to establish optimal treatment protocols.

This review assessed evidence on laser therapies for alopecia areata, reporting that the 308-nm excimer laser showed hair regrowth in several studies, while more research is needed for other laser types.

This review discusses the applications and advantages of LED-based photobiomodulation therapy for dermatological and cosmetic purposes but highlights existing challenges and health concerns while exploring future perspectives.

In this study, a square pulse, low-fluence IPL device used at home significantly reduced terminal hair count by 87% six months post-treatment, with evidence of hair miniaturization similar to professional laser treatments.

This review discusses the application of active transdermal technologies in cosmetic devices for skin restoration and enhancement, reporting no new clinical results.

In this study, low-level light therapy using a new helmet-type device significantly increased hair density and thickness in patients with androgenetic alopecia, showing no adverse events or side effects, suggesting it may be a safe and effective treatment option for both sexes.

This article provides new treatment guidelines for AA based on expert consensus while integrating regional healthcare variations, but it reports no new clinical results.

This study found that using a wearable low-level light therapy device for photodynamic therapy significantly reduced actinic keratosis lesions and improved quality of life in patients with AK of the scalp.

This study found that active telethermography could help identify cancerization fields in individuals with actinic keratosis by detecting hyperthermic halos around tumors, which showed significant changes after treatment with a photolyase device.

This study reported that a low color temperature light (1900 K) may have positive effects on melatonin secretion, eye protection, wound healing, and hair regeneration compared to higher temperature lights.

In this randomized, double-blind trial, researchers observed that low-level laser therapy led to significantly greater hair regrowth on treated areas compared to a sham treatment in patients with androgenetic alopecia over 24 weeks, suggesting it as a potentially effective and safe option.

This review found promising evidence for the efficacy of certain laser and light-based therapies in treating various forms of alopecia, such as low-level light therapy for androgenetic alopecia and excimer laser for alopecia areata, but emphasized the need for further understanding of these treatments.

This review discusses the challenges in selecting optical parameters for photobiomodulation studies on hair regrowth and wound healing, reporting no new clinical results and recommending more rigorous, standardized research approaches.

This narrative review concluded that facial aging involves complex anatomical changes that require multimodal rejuvenation approaches, integrating fillers, collagen stimulators, botulinum toxin, and energy-based devices for effective results, while emphasizing the need for scientific evidence and patient safety in aesthetic treatments.

This article reviews home-use laser and intense pulsed light systems for hair removal and growth, noting limited efficacy and safety data and emphasizing the need for long-term studies.

This clinical review evaluates current evidence on various adjunctive therapies for androgenetic alopecia, highlighting modest benefits for some interventions but emphasizing significant gaps and the need for rigorous, high-quality research to guide effective management strategies.

This study found that long-term use of a home-use LED device for neck skin rejuvenation significantly improved wrinkle appearance and skin biophysical parameters without affecting thyroid function or morphology after 16 weeks of daily use.

In this study, researchers developed a wearable red and blue LED patch and a sprayable fibrin gel to treat infected wounds at home, demonstrating effective infection control and enhanced wound healing in diabetic mice and minipigs.

In this chapter, the authors provide a detailed overview of the fundamental science and operational principles of radiofrequency technologies, particularly in enhancing liposuction procedures through minimally-invasive techniques like RF-assisted lipolysis and fractional RF subdermal treatment.

Follow these guidelines to safely and effectively use energy-based devices in aesthetic treatments.

This study found that FDA-approved low-level light/laser therapy devices significantly increased hair density in individuals with pattern hair loss compared to sham devices.

This study found that using a commercially available IPL home-use device led to significant hair reduction and demonstrated long-term efficacy in maintaining hair reduction one year after treatment.

This study utilized advanced imaging techniques to quantify hair damage and dye uptake dynamics, revealing that compound penetration in hair is influenced by molecule size and lipophilicity.

This review explores low-level light therapy's potential as a noninvasive treatment for various forms of alopecia, noting its promising results in hair regrowth and density but highlighting the need for standardized protocols and further research.
