Photoaging is the premature aging of Skintology
MD Review your skin due to repeated and long exposures to UVA and UVB rays from natural or artificial light. It creates epidermal (outer skin layer) changes, with damage that reaches to the cellular levels and its other components. It also promotes the breakdown of collagen and elastin, components that make your skin smooth and elastic.
What actually happens in photoaging is that the ultraviolet rays from the sun penetrate to your skin which destroys and reduces collagen. Once UV rays hits your skin it generates the production of ROS (reactive oxygen species) which damages your skin cells as well as collagen fibers. In addition to that, it also reduces the production of the transforming growth factor which is responsible for collagen production.
The damaging effects of too much sun exposure can leave you with irregularly pigmented skin, laxity, deep coarse wrinkles, skin dryness, leathery appearance, age spots and liver spots. This will make you look way more than your age and can even make you prone to cancer, with premalignant lesions also associated with the photoaging process.
This is the reason why you must avoid long sun exposures. A study has shown that UVA rays are the ones responsible for the damaging effects of photoaging because of its stronger wavelength that reaches farther down to the inner layers of your skin. It leaves what is called a solar scar on your skin that takes the form of a wrinkle. So the more repeated exposures you have, you can just imagine what your body, most especially your face would look like.
