Photoaging or photoageing (also known as dermatoheliosis) is a term used for the characteristic changes to skin induced by chronic UVA and UVB exposure. Tretinoin is the best studied retinoid in the treatment of photoaging.The deterioration of biological functions and ability to manage metabolic stress is one of the major consequences of the aging process. Aging is a complex, progressive process that leads to functional and esthetic changes in the skin.his process can result from both intrinsic (i.e., genetically determined) as well as extrinsic processes (i.e., environmental factors). Photoaging is attributed to continuous, long-term exposure to ultraviolet (UV) radiation of approximately 300â400 nm, either natural or synthetic, on an intrinsically aged skin.
The Dodge and Burn tools in Photoshop are the digital versions of these techniques and are often used to either lighten underexposed areas of a photo or darken overexposed areas. As useful as the Dodge and Burn tools are, however, they both suffer from a serious problem. Both of them cause permanent damage to your image, and this is never a good thing. The best way to work in Photoshop is to keep your original pixel information intact so you always have the original photo to fall back on.
