How to Prevent Photoaging? [PDF]

Journal of Investigative Dermatology, 2005
There are several theories on photoaging and its etiology. At this time, however, the only defenses commonly believed to prevent photoaging are the use of sunscreens to reduce the amount of ultraviolet (UV) that reaches the skin, the use of retinoids to prevent production of collagenase and stimulate collagen production, and the use of antioxidants to ...

Photoaging of human skin [PDF]

Photodermatology, Photoimmunology & Photomedicine, 2000
Chronic sun exposure causes photoaging of human skin, a process that is characterized by clinical, histological and biochemical changes which differ from alterations in chronologically aged but sun‐protected skin. Within recent years, substantial progress has been made in unraveling the underlying mechanisms of photoaging.

Adipose-Derived Mesenchymal Stem Cells (AD-MSCs) against Ultraviolet (UV) Radiation Effects and the Skin Photoaging

Biomedicines, 2021
The skin is a natural barrier against the ultraviolet (UV) radiation of sunlight. The long-term and/or repetitive exposure to the sunlight and related UV radiation may change the skin structure, decreasing collagen production, promoting premature skin ...

Marine Bioactive Peptides: Anti-Photoaging Mechanisms and Potential Skin Protective Effects

Current Issues in Molecular Biology
Skin photoaging, resulting from prolonged exposure to ultraviolet radiation, is a form of exogenous aging that not only impacts the aesthetic aspect of the skin but also exhibits a strong correlation with the onset of skin cancer. Nonetheless, the safety

Aging in elderly: Chronological versus photoaging

Indian Journal of Dermatology, 2012
Background: Skin is a window to aging changes, a biological reality. There is a dearth of studies regarding the various chronological (intrinsic) aging and photoaging (extrinsic) changes seen in Asians.

A Cross-Sectional Study of Platelet-to-Lymphocyte Ratio in Relation to Pigment Cell Nevi and Atypical Mole Syndrome. [PDF]

Health Sci Rep
ABSTRACT Background and Aims Melanocytic nevi (MN) and atypical melanocytic nevi (AMN) are established risk factors for cutaneous malignant melanoma (CMM), with patients exhibiting atypical mole syndrome (AMS) facing an even greater risk. Peripheral blood biomarkers—including neutrophil‐to‐lymphocyte ratio (NLR), eosinophil‐to‐lymphocyte ratio (ELR ...

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.
