This article reviews the growing trend of at-home laser and light devices for treating conditions like acne, hair removal, and psoriasis, emphasizing their popularity and the need for cautious use but reports no new clinical results.

This article reviews the use of laser and light technologies in hair treatments, highlighting their potential and challenges, but provides no new clinical findings.

This study observed that infrared light therapy, alone or combined with hyaluronic acid and calcium hydroxylapatite, effectively improved skin laxity with high patient satisfaction and minimal adverse effects among women aged 37 to 68.

This article reviews the use of light-based technologies for hair removal, detailing different laser systems and treatment protocols, but reports no new clinical results.

This study concluded that both low and incremental radiant exposures of diode lasers produced similar hair reduction and patient satisfaction, but low radiant exposure was less painful and better tolerated.

Higher fluence low-level laser therapy effectively promotes hair growth in androgenetic alopecia, with varying effects based on sex.

This observational study reports that a TRASER device using specific wavelengths for vascular and follicular targets showed both clinical responses and histological changes, suggesting its potential as an effective vascular and hair removal tool.

This study reports that using LED polarized magnification in hair transplant recipient sites can reduce eye strain and improve ease of site creation, but offers no graft placement advantage over traditional methods.

This study demonstrated that visible light lightens blond hair more effectively than ultraviolet light, attacking melanin granules directly, whereas ultraviolet light primarily damages other hair tissues following washing.

This article discusses the potential of combining growth factor therapy with LLLT LED therapy for hair regrowth in androgenetic alopecia, but it does not report new clinical results.

Light can be used to stimulate ear hair cells, improving speed and consistency over previous methods.

In this study, LED therapy for eyebrow loss in older females with frontal fibrosing alopecia significantly increased eyebrow hair count after 10 treatments and maintained improvement at 6 months, indicating it could be a promising and well-tolerated treatment option.

In this clinical study, low-level laser therapy using the HANDI-DOME LASER device increased hair counts by 51% compared to controls, indicating its potential as a safe and effective treatment for androgenetic alopecia in women aged 18 to 60.

This study found that ultraviolet light-enhanced visualization can detect subtle skin changes linked to carotene and vitamin A deficiency, which improved with dietary correction in deficient individuals.

In this study, helium-neon laser irradiation at approximately 1 J/cm² significantly increased the percentage of hair follicles in the anagen phase in both testosterone-treated and untreated mice, suggesting stimulation of hair growth.

This article reviews the basics of hair follicle biology, laser/tissue interactions, and hirsutism and hypertrichosis causes, discussing the long-pulsed alexandrite laser's role in hair reduction without reporting new clinical results.

This review discusses the modest efficacy of home-use laser and light devices for conditions like hair removal and acne, noting limited evidence and a lack of robust trials.

This study found that near-infrared LED therapy enhanced ATP synthesis, reduced reactive oxygen species, and promoted collagen production and hair growth more effectively than white LEDs in human skin cells and a photoaging mouse model.

This review discusses low-level light therapy for androgenetic alopecia and female pattern hair loss, noting minimal clinical evidence on its efficacy and the need for more controlled studies.

This study found that low level laser therapy at 655 nm significantly increased hair counts in males with androgenetic alopecia.

The Epilight Hair Removal System is effective for temporary hair removal with few side effects, but more research is needed to confirm its safety and long-term results.

In this study, researchers developed hyaluronic acid derivatives functionalized with nitric oxide photodonors for light-activated skin treatments, finding that the compounds released NO under blue light and enhanced keratinocyte proliferation and migration, suggesting potential for therapeutic use.

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.

This case series reports that home use of intense pulsed light devices may effectively reduce hair burden and prevent recurrence of pilonidal disease in patients unable to regularly attend clinic sessions.

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.

This review discusses the development of IPL devices, highlights their established cosmetic uses, such as treating vascular and pigmented lesions, and suggests potential expansion into more effective combination therapies.

This study concluded that low-level fluence 810 nm diode laser therapy was generally well tolerated, safe, and effective for long-term hair reduction in a small sample of patients with various skin types.

This paper from dermatology experts discusses their affiliations and declares no significant commercial interests, but it reports no research findings.

This study demonstrated that a new technology combining microneedle patches, stem cell exosomes, and light therapy effectively promoted hair regrowth in animal models within 7 days compared to conventional treatments.

This study reported that the new near-infrared LED device showed significant improvements in skin rejuvenation and a slight increase in hair growth, with further research recommended for broader validation.
