This case report describes a child with hypopigmented mycosis fungoides successfully treated with UVA1 light therapy.

This study found that isolated red light may serve as an alternative for photo-immunotherapy without additional photosensitizers, as it did not reduce keratinocyte differentiation markers or increase photo-oxidative damage, unlike treatment with IL-4 or UVA1/blue light.

This review concluded that LED-based photobiomodulation is generally safe and effective for certain dermatologic conditions, though consumer devices often show less efficacy compared to professional systems.

This study found that a hydro-alcoholic extract of Roselle petals may reduce free radical production during UV-induced photodecomposition of antibiotics, potentially offering protective benefits for patients using similar topical antibiotics.

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 highlights evidence supporting the potential of blue light therapy as a non-invasive treatment for managing skin and hair conditions by modulating interactions between the skin microbiome and its host.

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 review discusses the effectiveness of non-thermal, non-ablative devices like light-emitting diodes in treating various skin and hair conditions but reports no new clinical findings.

This study concludes that egg shell membrane hydrolysates, particularly Fraction I, may effectively mitigate UV-B radiation-induced wrinkles and promote skin collagen and hyaluronic acid production, suggesting potential use in functional cosmetics.

This study reports cases of androgenetic alopecia patients with depigmented macules on sun-exposed scalp areas, suggesting potential ultraviolet-induced scalp leukoderma not covered in existing dermatology texts.

This study reported that narrowband UVB treatment significantly increased WNT7B, WNT10B, and TCF7L2 gene expression in lesional skin of psoriasis patients, suggesting these genes may play a role in psoriasis pathogenesis.

Red and infrared light therapy improves hair growth in balding patients.

In this article, researchers explored how blue light exposure affects the scalp and hair follicles, highlighting oxidative stress and hair growth disruptions, while emphasizing the importance of protective strategies like antioxidants and limiting light exposure.

This study found that low-level pulsed wave red light stimulated collagen and ATP production in human fibroblasts with significantly shorter treatment time than continuous wave light, suggesting enhanced consumer compliance for skin treatments.

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

This study used a 3D simulation to show that human hair provides varying levels of UV protection depending on head orientation and hair alignment, highlighting hair's role in scalp UV protection, especially for those with alopecia.

This study reviews the pharmacological properties of the plant Eclipta prostrata, highlighting its potential in treating various conditions including wound healing, diabetes, liver protection, alopecia, gum disease, cancer prevention, bone health, and antimicrobial effects, alongside its traditional use in tropical regions.

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, researchers observed that dietary vitamin D intake and light exposure play a crucial role in vitamin D metabolism in mice, suggesting similar importance for human health in maintaining optimal vitamin D levels.

In this study involving children with alopecia areata, researchers found that adding narrowband UVB 311 nm therapy to standard treatment significantly improved hair regrowth in those with coexisting atopic dermatitis compared to those without the condition.

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 study observed that exposure to different wavelengths of light affects opsin and clock gene responses in skin cells, suggesting potential therapeutic approaches using photobiomodulation for dermatological conditions like psoriasis and wound healing.

In this study, researchers reported that chronic UV exposure may contribute to androgenic alopecia progression by influencing hair cycle changes and exacerbating solar elastosis in the scalp.

The researchers reported that cancer incidences are rising over time in developed countries, with potential carcinogenic drivers including advancing age, estrogen, decreasing vitamin D3, and Human Papillomavirus.

In this study using SKH-1 mice, researchers observed that acute UVB exposure increased expression of retinoid metabolism proteins and decreased retinol storage enzyme levels, suggesting enhanced retinoic acid synthesis in the epidermis.

This study reported that using UVB preirradiation and anti-CD154 antibody treatment in a humanized mouse model prolonged hair follicle allograft survival and reduced immune cell infiltration without needing generalized immunosuppression.

This case report identified UVB photosensitivity and testicular failure as previously unreported components of low-sulfur hair syndrome in a 16-year-old male.

This review evaluates the potential benefits and mechanisms of blue light therapy for skin conditions like atopic dermatitis and acne, but highlights the need for further research on safety and clinical protocols.

The skin acts like an endocrine organ, making hormones that affect skin diseases and respond to stress.

In this study, researchers found that Ectoin, derived from halophilic bacteria, can mitigate stress-related skin damage by reducing cortisone's inhibitory effects on essential skin proteins and decreasing UVB-induced glucocorticoid activity, highlighting its potential as a preventative agent for stress-induced skin issues.
