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.
Mounting is the method in which it is displayed. For example, you can mount a photo in your photo album using just mounting corners, or you can put a pic in a frame and hang it on the wall; some photos are displayed by gluing them to hardboard.
