Iron Metabolism in Skin: Implications for Skin Ageing and Health

Iron Metabolism in Skin: Implications for Skin Ageing and Health

Posted on by skin_challenges
Schematic depiction of the iron metabolism in the epidermis. The process of keratinocyte differentiation is represented by cells in the basal layer, the granular layer and the cornified layer. The distribution of iron-binding proteins and regulators of iron metabolism and transport is shown according to the evidence and hypotheses discussed in the main text. Alternative…

The hallmarks of aging as a conceptual framework for health and longevity research

The hallmarks of aging as a conceptual framework for health and longevity research

Posted on by skin_challenges
In a comprehensive review led by José M. P. Freije from the Universidad de Oviedo, Spain, the transformative impact of The Hallmarks of Aging framework in understanding longevity was explored in depth. Originally proposed in 2013 and recently updated to include three new hallmarks, this framework categorizes aging into primary, antagonistic, and integrative factors, offering…

Aging Skin and Wound Healing

Aging Skin and Wound Healing

Posted on by skin_challenges
Recent research, led by Nicole Burkemper from SSM Saint Louis University Hospital, USA, and published in Clinics in Geriatric Medicine (Elsevier),  challenges previous notions about wound healing in the elderly, suggesting that it’s not inherently defective but rather delayed. Human skin, responsible for essential life functions, undergoes significant changes with aging and photodamage. While chronic…

Human Skin Microbiome Odorants Influence on Mosquito Landing Behavior

Human Skin Microbiome Odorants Influence on Mosquito Landing Behavior

Posted on by skin_challenges
In a recent study published in Scientific Reports by Nature, researchers led by Omar S. Akbari from the University of California, San Diego, have uncovered the potential of the human skin microbiome in repelling mosquito bites and limiting the transmission of deadly diseases. Mosquitoes are lured by specific scents emitted by human skin, predominantly generated…

Turning back the clock on photoaging skin

Turning back the clock on photoaging skin

Posted on by skin_challenges
Chronic exposure of human skin to ultraviolet light causes premature aging, or photoaging. As the skin undergoes photoaging, type I collagen bundles, which are found in the dermis beneath the top layer of the skin and provide strength and support to skin, become fragmented. This leads to wrinkles, fragility and loss of support and elasticity.  …
