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.

Dietary monounsaturated fatty acids intake and risk of skin photoaging. [PDF]

PLoS ONE, 2012
Intake of monounsaturated fatty acids has been reported to reduce oxidative stress, insulin resistance and related inflammatory processes and may thus protect from skin photoaging.

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

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.

Revitalizing Photoaging Skin through Eugenol in UVB-Exposed Hairless Mice: Mechanistic Insights from Integrated Multi-Omics

Antioxidants
Chronic ultraviolet (UV) exposure causes photoaging, which is primarily responsible for skin damage. Nutritional intervention is a viable strategy for preventing and treating skin photoaging.

Photoaging/photodamage and photoprotection

Journal of the American Academy of Dermatology, 1990
Exposure to sunlight can produce both acute and long-term effects. Acute changes include erythema, photosensitivity, and immunologic alterations. Long-term consequences include carcinogenesis and photoaging. All effects can be minimized by photoprotection. This article reviews the adverse effects of sun exposure and strategies to reduce photodamage.

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 ...

Autophagy-Enhancing Properties of Hedyotis diffusa Extracts in HaCaT Keratinocytes: Potential as an Anti-Photoaging Cosmetic Ingredient

Molecules
The decline in autophagy disrupts homeostasis in skin cells, leading to oxidative stress, energy deficiency, and inflammation—all key contributors to skin photoaging.

Impact of ultraviolet radiation‐induced damage to hair fiber integrity: A multi‐technique physicochemical characterization of surface and cortex properties

International Journal of Cosmetic Science, EarlyView.
UV exposure induces cuticular and cortical damage in natural hair, with oxidative effects and protein degradation comparable to bleaching. However, double bleaching leads to significantly greater structural degradation, emphasizing distinct mechanisms and severity of chemical versus UV‐induced damage. Abstract The combination of chemist techniques is a

Photo-Aging of Biodegradable Polylactic Acid Microplastics [PDF]

E3S Web of Conferences
Microplastic (MPs) pollution has became a serious issue. Photoaging is one of the main ways to produce MPs. Polylactic acid (PLA) is the most commonly used biodegradable plastic in industry, however, the current reports on the quantitative data of ...
