A study published in Journal of the Mechanical Behavior of Biomedical Materials found that wrinkled skin is caused by its tendency to buckle under pressure due to age-related changes in its mechanical properties. As people age, their skin becomes more prone to wrinkles as it stretches and contracts in different directions.
Researchers from Binghamton University confirm the long-held 'urban myth' that saltwater dries out skin, increasing tissue stiffness and stress. A simple solution to alleviate tightness is taking a shower after coming out of the ocean.
A KAIST team created a face-conforming LED mask with improved efficacy in skin rejuvenation. The FSLED mask demonstrated a 340% improvement in deep skin elasticity compared to conventional masks, showing significant benefits for anti-aging treatment.
A new study has identified novel strains of microbes that have adapted to use limited resources in cities, including those found in Hong Kong's subways and skin. These microbes can metabolize manufactured products, posing health risks if they are pathogenic.
Researchers from Osaka Metropolitan University have discovered that disruptions in the basement membrane zone between the epidermis and dermis could make it harder for pigment-producing cells to adhere. An enzyme called matrix metalloproteinase 2 (MMP2) may be overexpressed, leading to disturbance of the basement membrane.
A large study found a significant link between vitamin D levels and psoriasis severity, with lower levels associated with greater severity. The research suggests that a vitamin D-rich diet or oral supplementation may provide benefits for individuals with psoriasis.
Researchers found that daily consumption of dealcoholized muscadine wine for six weeks improved skin elasticity and barrier function, while reducing inflammation and oxidative stress. Although wrinkles were not significantly affected, participants showed significant improvements in skin smoothness.
Researchers have found that spiny mice possess bony plates called osteoderms in their tails, a feature previously thought to be exclusive to armadillos. The discovery reveals that osteoderms can emerge and disappear multiple times in vertebrates throughout evolution.
A new study presents a chronic wound murine model that characterizes the role of persistent senescent cell accumulation in delayed wound closure. The molecular profiles of senescent cells demonstrate the adverse influence of SASP factors, highlighting a potential root-cause-driven therapeutic strategy.
Researchers at Binghamton University have discovered that human skin's unique structure allows it to maximize both durability and flexibility. The team created artificial skin membranes that mimicked the structure of mammalian skin, testing their puncture toughness and deformability.
A new study found that the same bacteria are present in the dermis layer of skin across all ages and genders, contradicting the long-held assumption that each person's microbiome is unique. This discovery has significant implications for understanding skin disorders like eczema and psoriasis.
Researchers discovered that melanoma sends tiny vesicles containing microRNA before spreading, inducing morphological changes in the dermis. They found promising chemical substances to block this process, offering hope for a cure for the deadly disease.
Research suggests differences in oil-secreting glands and dermis thickness contribute to wrinkle formation. The study, published in Clinical Anatomy, found shallower wrinkles on the forehead compared to the outer eye area.
Researchers at Berkeley Lab's Advanced Light Source observed the micro-scale mechanisms behind skin's remarkable tear resistance. The study identified four synergistic mechanisms in collagen that act to diminish stress concentrations associated with tears.
