This special issue reviews various advances in laser and light-based technologies for dermatological treatments, emphasizing improvements for diverse skin types, but reports no new empirical results.

This study found that a high-power triple-wavelength diode laser effectively and safely treated facial hirsutism and follicular disorders in individuals with darker skin tones, showing significant hair reduction without adverse events.

This review discusses the potential enhanced effectiveness of combining Eflornithine cream with laser or light-based systems for facial hair removal and emphasizes the need for safer and more satisfactory solutions.

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 review reported that home-use laser and intense pulsed light devices effectively reduce hair with significant efficacy and safety, showing 80% hair reduction one year post-treatment, although results can vary for darker skin types and compared to professional devices.

In this observational study, the effectiveness of a diode laser was evaluated for treating pseudofolliculitis barbae at the Laser and Skin Surgery Center of New York, but it reports no new clinical results.

This review discusses the evolution and potential of photobiomodulation therapy, highlighting its transition from skepticism to recognition in medical research; it reports no new experimental findings.

Laser treatment boosts hair growth by activating a key growth factor.

This study evaluated the effectiveness of a 675 nm laser device on facial acne scars in patients with darker skin types, finding that 67% reported excellent improvement and 33% reported good improvement, with significant enhancements in skin texture and appearance after five treatments.

This study found that Low Power Laser therapy may be an effective complementary treatment for scalp alopecia and crural ulcers, showing quicker and potentially better results than conventional treatments.

This review discusses the factors affecting laser hair removal results and adverse events, emphasizing the need for more research to determine optimal treatment parameters; it reports no new clinical findings.

This article introduces a special issue of "Lasers in Surgery and Medicine" focused on dermatology and plastic surgery, but it presents no new research findings.

This study found that anagen-phase hair follicles in mice are particularly sensitive to damage by ruby laser pulses, resulting in alopecia without scarring, suggesting enhanced laser hair removal strategies.

This study found that the LightSheer Diode EP Laser System significantly reduced hair growth among women with hirsutism, with side effects disappearing within three days and no long-term skin pigmentation issues observed.

This study reviews the use of lasers and light therapies as treatment options for managing the two most common types of alopecia—androegenetic alopecia and alopecia areata—highlighting that existing FDA-approved drugs like minoxidil and finasteride are partially effective, necessitating additional therapeutic approaches.

In this study, the Avalanche brushing protocol demonstrated similar hair reduction effectiveness to the stamping method, but with significantly lower discomfort reported by patients, suggesting it may be preferable for individuals with sensitive skin or dense hair in early treatment sessions.

This study suggests that selective photothermolysis of sebaceous glands using free electron laser pulses may offer a novel approach to treating acne by causing targeted thermal damage without affecting the epidermis.

This review discusses advancements in laser hair removal technologies and the potential role of radiofrequency for certain hair types, but it reports no new clinical results.

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.

The study's findings are unreliable due to retraction.

This study describes a new intravital microscopy method for observing intestinal regeneration by tracking crypt dynamics in living mice after laser-induced tissue damage, revealing events like crypt fission, fusion, and disappearance over multiple weeks.

This case report describes the first use of photobiomodulation therapy with a continuous wave red laser (660 nm) as monotherapy for alopecia areata, resulting in significant hair regrowth within 7 days, though further research is needed for conclusive evidence.

In this study, a triple wavelength laser was found to be highly effective and well-tolerated for reducing hair in Indian women with Fitzpatrick skin types III and IV, achieving an average hair count reduction of 86.5%, with only mild and transient adverse effects observed.

This study compared the microscopic treatment zones created by different fractional lasers and radiofrequency in swine skin, finding distinct patterns and damage levels for each technology.

Laser treatment shows promise for hair growth, but needs further research.

The study suggests that CO₂ laser creates hair transplant channels with significantly less lateral thermal damage than Ho:YAG laser in the human scalp.

This study found that NB-002 demonstrated clear antifungal activity and clinically significant nail clearing in subjects with distal subungual onychomycosis and ≤50% nail involvement, compared to a vehicle treatment.

This study found that low-output laser irradiation demonstrates biostimulatory effects on several biological systems and processes, including hair growth, wound healing, and immune function, with effects influenced by dose and exhibiting both stimulatory and inhibitory potential.
