Discovery of matrix metalloproteinase inhibitors as anti-skin photoaging agents.

European journal of medicinal chemistry
Photodamage is the result of prolonged exposure of the skin to sunlight. This exposure causes an overexpression of matrix metalloproteinases (MMPs), leading to the abnormal degradation of collagen in the skin tissue and resulting in skin aging and damage.

PHOTOAGING AND TRETINOIN

Dermatologic Clinics, 1998
Premature skin aging caused by repeated exposure to solar radiation is called photoaging. Although once considered an irreversible process, it is now established that photoaging can be treated by topical tretinoin. Both from carefully designed controlled clinical studies; and basic investigations into the mechanism by which tretinoin improves photoaged

Photoaging: Mechanisms and repair

Journal of the American Academy of Dermatology, 2006
Aging is a complex, multifactorial process resulting in several functional and esthetic changes in the skin. These changes result from intrinsic as well as extrinsic processes, such as ultraviolet radiation. Recent advances in skin biology have increased our understanding of skin homeostasis and the aging process, as well as the mechanisms by which ...

Differential photoaging behaviors of different colored commercial polyethylene microplastics in water: The important role of color characteristics.

Science of the Total Environment
Upon entering the environment, plastics would undergo photoaging and forming microplastics (MPs). However, information on the photoaging behavior of colored MPs and how the color characteristics (wavelength, lightness, and saturation) influence their ...

Photoaging and oxidative stress

Experimental Dermatology, 2003
Abstract Photoaging is significantly different from chronological aging in both clinical and histological appearance. It has been suggested that oxidative stress, generated by ultraviolet radiation (UVR), leads to photoaging over a long period. The presence of 8‐OHdG, and oxidatively modified proteins such as 4‐hydroxy‐2‐nonenal‐modified protein, 3‐l ...
