Amphibian‐Derived Peptide OA‐AL14 Alleviates UVB‐Induced Skin Photoaging via Autophagy Activation Mediated by the AMPK/mTOR Pathway

Integrative Zoology, EarlyView.
The schematic diagram illustrates that the amphibian‐derived peptide OA‐AL14 protects against UVB‐induced skin photoaging through a dual mechanism: activating the Nrf2 pathway to counteract oxidative stress and modulating the AMPK/mTOR axis to induce protective autophagy. ABSTRACT Skin photoaging, primarily driven by ultraviolet B (UVB) radiation, is a

Demographic Analysis of the Sun Protective Behaviours and Skin Cancer Risk of Victorian Farmers

Australasian Journal of Dermatology, EarlyView.
ABSTRACT Background Farmers have an elevated risk of melanoma and non‐melanoma skin cancer due to their occupational exposure to high levels of ultraviolet radiation. The sun protective behaviours of farmers are poorly understood, limiting targeted interventions to this at‐risk population.

Exploring and Comparing the Psychosocial Impacts of Vitiligo on a Broader Scale: An International Survey via the Use of Social Media

Australasian Journal of Dermatology, EarlyView.
ABSTRACT Background/Objectives Vitiligo is associated with substantial psychosocial burden; however, community‐based patient‐reported data remain limited, and existing instruments may not fully reflect patients' lived experience. This study explored the psychosocial impacts of vitiligo using social media‐based recruitment.

A guideline of antiphotoaging activity of polysaccharide assay in vitro and in vivo

eFood, 2023
People have become increasingly concerned about skin beauty and health issues, especially skin photoaging. Previous studies showed that skin photoaging was characterized by skin roughness and dryness.

Allergen Content of Inactive Ingredients in Best‐Selling Sunscreens: A Comparison of Key Product Features

Contact Dermatitis, EarlyView.
Allergenic risk of sunscreen active ingredients is well known, but that of inactive ingredients remains understudied. We identified and quantified allergens found in inactive ingredients of best‐selling sunscreens and developed a free tool (www.NAC80.com) that helps dermatologists recognise higher‐risk products and counsel patients prone to allergic or

Possible Involvement of Basement Membrane Damage in Skin Photoaging

, 2009
Aging of sun-exposed skin is accelerated by three major environmental factors: UV radiation, dryness, and oxidation. UV radiation exposure is the most influential factor in skin aging (so-called photoaging).

Extracellular matrix and proteolysis: mechanisms driving irreversible changes and shaping cell behavior

The FEBS Journal, EarlyView.
Irreversible ECM proteolysis by remodeling enzymes shapes development, homeostasis, and disease. ECM‐degrading proteases display cell specificity and are governed by shared mechanisms, exhibiting functional redundancy in generating matrikines, growth factors, and cytokines.

Effects of visible light on mechanisms of skin photoaging

, 2021
Human skin is not only affected by ultraviolet radiation but also by visible light wavelengths emitted by sunlight, electronic devices, and light emitting diodes. Similar to the ultraviolet radiation, visible light has been implicated in photoaging.

An update on the landscape of collagen bioactive fragments

The FEBS Journal, EarlyView.
The remodeling of the extracellular matrix releases collagen bioactive fragments, which exert molecular functions and regulate numerous biological processes via several signaling pathways. Here, we summarize the latest findings describing the roles of major bioactive fragments from collagens I, IV, VI, and XVIII in various physiological and ...

Unravelling polyphenol skin permeation: A comparative study using full‐thickness 3D in vitro and ex vivo human skin models

International Journal of Cosmetic Science, EarlyView.
This study demonstrates that full‐thickness 3D in vitro skin models reliably assess the permeation of cosmetic polyphenols, revealing compound‐specific transport profiles and bridging the gap between conventional cell models and ex vivo human skin, while offering an ethical and robust alternative for dermal absorption screening. Abstract The evaluation
