research 6. Phototherapy, Photomedicine, and Pigmentary Disorders
Stopping certain drugs can improve skin conditions, arsenicosis affects over half of a Bangladeshi village, males are more vulnerable, and certain treatments are effective for warts, acne, and psoriasis. Smoking and drinking are linked to psoriasis in men, a cream helps with a type of skin cancer, and low iron levels don't directly cause chronic hair loss in women.
research The melanocyte photosensory system in the human skin
Human skin's melanocytes respond to light by changing shape, producing pigments and hormones, which may affect sleep patterns.
research Sunscreens and Hair Photoprotection
Hair sunscreens are important for maintaining hair's cosmetic value.
research Photodegradation of human hair: a microscopy study
UV radiation significantly damages hair, especially with humidity, making it more vulnerable to further damage.
research Increased calcidiol level in redhaired people: Could redheadedness be an adaptation to temperate climate?
Redheaded people have higher levels of a vitamin D precursor, suggesting red hair may be an adaptation for better vitamin D synthesis in areas with less sunlight.
research ADSCs inhibit photoaging‐ and photocarcinogenesis‐related inflammatory responses and extracellular matrix degradation
ADSCs help protect skin from UV damage and aging.
research Identification of ultraviolet B radiation-induced microRNAs in normal human dermal papilla cells
UVB radiation changes the levels of certain microRNAs in skin cells, which may affect cell survival and hair growth.
research The risk of hydroquinone and sunscreen over-absorption via photodamaged skin is not greater in senescent skin as compared to young skin: Nude mouse as an animal model
Aging and sun damage do not increase the skin's absorption of certain sunscreens and drugs.
research Photosensitized 2-amino-3-hydroxypyridine-induced mitochondrial apoptosis via Smac/DIABLO in human skin cells
Using A132 hair dye with sunlight can cause skin damage and hair loss.
research Retinoids and Phototherapy for Psoriasis
Retinoids and narrowband UVB phototherapy are effective for treating psoriasis and can reduce treatment time when used together.
research Effects of ultraviolet B radiation on physicochemical properties of human hair shaft
UVB radiation changes the chemical makeup and dries out human hair but doesn't alter its appearance or texture.
research 583 Induction of type 17 collagen decreases ultraviolet b-induced cellular senescence in human htert/ker-ct keratinocytes
Increasing type 17 collagen reduces aging signs in skin cells caused by UV light.
research Skin, Genetic Defects, and Aging
Genetic defects and UV radiation cause skin damage and aging.
research Ultraviolet B irradiation increases the expression of inflammatory cytokines in cultured sebocytes
UV-B light increases inflammation-related substances in acne-related skin cells.
research Increased 25(OH)D3 level in redheaded people: Could redheadedness be an adaptation to temperate climate?
Redheaded people may have evolved to efficiently make vitamin D in areas with less sunlight.
research UV radiation, vitamin D and epidermal carcinogenesis
Vitamin D may help protect against nonmelanoma skin cancer.
research Preparation and In Vitro Evaluation of Protective Effects of Quercetin‐Loaded Solid Lipid Nanoparticles on Human Hair Against UV ‐B Radiation
Quercetin-loaded nanoparticles protect human hair from UV-B damage.
research Ligand‐Independent Actions of the Vitamin D Receptor: More Questions Than Answers
The vitamin D receptor can act without its usual activating molecule, affecting hair growth and skin cancer, but its full range of actions is not well understood.
research Anomalous Fluorescence of White Hair Compared to Other Unpigmented Keratin Fibres
White hair has weaker tryptophan fluorescence than other unpigmented fibers, possibly due to UV exposure or unknown substances.
research Carbonylation of hair proteins: A robust biomarker of molecular and structural oxidative damage in hair fibres
Protein carbonylation is a sensitive marker for oxidative damage in hair, especially from light exposure.
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 The riddle of genuine skin microrelief and wrinkles
Different types of wrinkles need specific treatments.
research Head and Neck Melanoma Incidence Trends in the Pediatric, Adolescent, and Young Adult Population of the United States and Canada, 1995-2014
Head and neck melanoma cases rose by 51.1% in young males aged 15-39 from 1995 to 2014.
research Topical sunscreens and vitamin D
Hair loss treatments show limited improvement, sunscreen thickness affects vitamin D production, and the effectiveness of IVIg for toxic epidermal necrolysis is uncertain.
research A fast and simple FIA-chemiluminescence method for the evaluation of Roselle flowers as scavenger of the free radicals generated by UV irradiated antibiotics
Roselle flower extracts can protect against free radical damage in UV-irradiated antibiotics.
research Smart Fluids As Autophagy-Activating Photoprotectors: In Vitro Analysis of Dead Sea Water and Magnetized Saline Water Against Ultraviolet B (UVB)-Induced Photodamage in Human Keratinocytes
Dead Sea water and magnetized saline water can protect skin from UVB damage by activating autophagy.
research Androgenic Alopecia and Stress-Induced Premature Senescence by Cumulative Ultraviolet Light Exposure
Chronic exposure to sunlight may worsen male pattern baldness and protecting the scalp from the sun could slow it down.
research Oxidative Modification in Human Hair: The Effect of the Levels of Cu (II ) Ions, UV Exposure and Hair Pigmentation
