research Adipose tissue protects against skin photodamage through CD151- and AdipoQ- EVs
Fat tissue vesicles protect skin from UV damage better than stem cell vesicles.
research 463 Spatial transcriptomics reveals an inflammatory profile in photoexposed light skin, which is absent in dark skin
Light skin shows more inflammation from sun exposure than dark skin.
research Weathering of the hairless scalp: a study using skin capacitance imaging and ultraviolet light-enhanced visualization
The study found that long-term sun exposure does not significantly affect follicular plugs on the scalp, and the scalp's appearance is unique compared to other body parts.
research Protein Kinase C Epsilon Signals Ultraviolet Light‐induced Cutaneous Damage and Development of Squamous Cell Carcinoma Possibly Through Induction of Specific Cytokines in a Paracrine Mechanism¶
Protein kinase C epsilon may promote skin cancer development after UV exposure by affecting nearby cells.
research Heterogeneity of Polymorphous Light Eruption: A Study of 105 Patients
The study found that polymorphous light eruption varies among patients and can be distinguished from benign summer light eruption by the time it takes for symptoms to appear after sun exposure.
research Flexural Agminated Eruptive Nevi in Langerhans Cell Histiocytosis
Sunlight exposure improved a patient's skin condition, and there may be a link between a certain disease and skin growths; a leukemia treatment caused changes in hair color and growth.
research Photoinduced formation of thiols in human hair
UV exposure damages hair, increasing thiols and altering protein structure.
research Photo-downregulation of SIRT4 mitigates aging in mice by enhancing H3K9ac via fatty acid metabolism
Red light exposure can slow aging in mice by improving fat metabolism.
research Melasma, a photoaging disorder
Melasma is now considered a skin aging disorder caused by sun exposure in people with a genetic tendency, which impacts treatment and prevention approaches.
research Characterization of Cutaneous Photoxicity Induced by Topical Alpha-Terthienyl and Ultraviolet A Radiation
Low-dose topical alpha-terthienyl may be a safer option for treating skin conditions with light therapy.
research In vivo and in vitro studies of anti-aging properties of Dendrobium sabin flower
Dendrobium sabin flower extract may help reduce skin aging from UV exposure.
research Hair removal using a long-pulsed alexandrite laser.
The long-pulsed alexandrite laser is effective for hair reduction, particularly for light-skinned individuals with dark hair, but caution is needed for darker skin.
research Disorders of hair
The document concludes that hair analysis is not good for assessing nutrition but can detect long-term heavy metal exposure.
research Lights triggered differential accumulation of antioxidant and antidiabetic secondary metabolites in callus culture of Eclipta alba L.
Red light boosts beneficial compounds in Eclipta alba cultures.
research Light Pollution and Oxidative Stress: Effects on Retina and Human Health
Excessive blue light harms eye cells and disrupts sleep patterns.
research 521 Deciphering Pathomechanisms in Solar Urticaria
The study found that skin inflammation and immune response pathways are activated in Solar Urticaria patients after UV exposure, unlike in healthy people.
research Light‐Activatable Hyaluronic Acid‐Derivatives Releasing Nitric Oxide and Their Delivery in the Skin
Light-activated hyaluronic acid derivatives can enhance skin healing and regeneration.
research Activation of Wnt/β-catenin signaling is involved in hair growth-promoting effect of 655-nm red light and LED in in vitro culture model
Red light and LED treatments help hair grow by activating a specific cell signaling pathway.
research The Therapeutic and Preventive Effects of Light‐Emitting Diode (LED ) for Post‐Inflammatory Erythema and Hyperpigmentation: A Pilot Study
830 nm LED light effectively treats and prevents skin redness and dark spots, while 590 nm LED light only helps prevent them.
research Red LED light promotes hair follicle development to improve fibre quality in Su line Angora rabbit
Red LED light improves the quality of Angora rabbit wool by promoting hair growth.
research 253 Opsins and Cryptochrome photoreceptors mediate blue light stimulatory effect on hair growth
Blue light helps hair growth by affecting specific proteins in hair follicle cells.
research The effect of blue light on the scalp and hair follicles
Blue light can damage hair and scalp, leading to hair loss.
research A Novel, Hand-Held, and Low-Level Light Therapy Device for the Treatment of Acne Vulgaris: A Single-Arm, Prospective Clinical Study
A new hand-held light therapy device was found to be safe and effective for treating mild-to-moderate acne.
research 644 Response of distinct human dermal fibroblast lineages to visible radiation: Potential for differential light-based therapy
Different types of human skin cells respond uniquely to various colors and doses of light, which could lead to specialized light treatments for skin conditions.
research Irradiation by high-intensity red light-emitting diode enhances human bone marrow mesenchymal stem cells osteogenic differentiation and mineralization through Wnt/β-catenin signaling pathway
High-intensity red LED light boosts bone cell growth and mineralization.
