This study found that an 800-nm diode laser was effective for reducing pigmented hair and extending hair plucking intervals, with most patients tolerating the procedure well without anesthetics.

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 found that while 450nm blue light can inhibit collagen and induce oxidative stress in dermal fibroblasts, 850nm near-infrared light may enhance metabolic activity without causing oxidative damage, suggesting potential for tailored light therapies in skin treatments.

This study found that LEDs at specific wavelengths may improve antifungal performance and promote hair growth by activating scalp cells without inducing inflammation compared to a non-irradiated group.

LED light helps human hair root cells grow and move by activating certain cell pathways.

This study found that using a home-use LED mask with specific wavelengths improved signs of skin aging in both ex-vivo and clinical settings.

This review examines various treatments for dissecting cellulitis, noting isotretinoin may offer the best chance for remission despite limited long-term data and calls for more clinical studies.

This review discusses the mechanisms, scientific support, and FDA clearance of photobiomodulation mask devices but reports no new research findings.

This study found that laser hair removal is optimal for light to moderate skin tones using 10-15 J/cm² at 755 nm and for dark skin with 4.5-10 J/cm² at 755-1064 nm.

Among individuals with skin types II and III, this study found the 755 nm laser more effective for axillary hair removal than the dual-wavelength laser, with a better safety profile and enduring results up to 12 months.

The study discusses using red light therapy for hair regrowth, noting red light alone may aid non-inflammatory hair loss, while infrared-red light combination is necessary for conditions like alopecia areata.

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 found that far-infrared radiation preconditioning significantly enhanced the proliferation, survival, and migration of bone marrow-derived stem cells in vitro, indicating potential therapeutic benefits for cardiac ischemia treatment.

This study found that a new hydrogel formulation of basic fibroblast growth factor showed promise in promoting hair regrowth and reducing inflammation in testosterone-treated mice.

Multiple-wavelength radiation helps hair grow by boosting early hair follicle development.

LED light helps hair follicle cells grow and prevents them from dying by activating certain cell pathways.

LED light helps human hair root cells grow and prevents them from dying by activating specific growth pathways.

This study found that both 5-ALA and Photofrin can effectively destroy human microvascular endothelial cells in vitro and cause tissue necrosis in vivo, with Photofrin showing greater efficacy at lower concentrations or power densities.

This study reviewed the effectiveness of long pulse 1,064-nm Nd:YAG laser treatments for leg veins, hair removal, and skin rejuvenation, highlighting its safety, particularly for darker skin types, due to reduced pigmentary side effect risks.

This ex vivo study reported that a 645-nm wavelength red-light laser can penetrate and reach cells in the various layers of swine oral mucosa and periosteum tissue samples.

This study proposes a simple fluorescence method to evaluate hair damage and protection, suggesting that emissive properties of hair can aid in substantiating cosmetic claims.

This review evaluates photobiomodulation's diverse clinical uses in sports and medicine, reporting physiological modulation and potential therapeutic benefits, but emphasizes the importance of precise dosimetry for success.

This study found that 830 nm LED light effectively treated post-inflammatory erythema and hyperpigmentation, while both 830 nm and 590 nm LEDs prevented post-inflammatory erythema.

This study found that 1064 nm QS Nd:YAG laser treatment effectively lightens hair and improves skin appearance in Indian subjects with minimal adverse effects, offering a safer alternative to chemical lightening products.

This review discusses the effects of photobiomodulation, particularly its potential to reduce inflammation in various conditions, but it does not report new clinical findings.

This review discusses the effects of visible light on human skin, highlighting its role in pigmentation, thermal damage, and the treatment of several skin conditions, while noting limited sunscreen protection against it; no new clinical results are reported.

This study observed that quiescent label-retaining cells in the intestine, identified by Paneth cell markers, can switch to a proliferative state and activate Bmi1 expression during tissue injury, contributing to tissue regeneration.

This review discusses the dermatologic features of PCOS as potential early indicators of the syndrome and notes that treatment of these conditions may enhance quality of life and psychological well-being, but it reports no new clinical results.

This review found that many low-level light therapy studies report beneficial effects but often fail to provide adequate measurement details, affecting the reliability and repeatability of the research.

In this review, the researchers highlight LED therapy as an emerging and safe treatment for skin inflammatory conditions, aging, and hair growth disorders, noting its integration into dermatological practice but emphasizing the need for more controlled studies to confirm its efficacy.
