Due to the increased longevity in contemporary society, study interest in skin ageing has increased during the past ten years. Skin ageing is an uneven process that is defined by epidermal and dermal abnormalities. It is also accompanied by a number of clinical symptoms, including skin dryness, colour changes, elasticity loss, wrinkles, and an increased risk of skin cancer. The ageing appearance of the skin is a result of both intrinsic or chronological ageing, which is influenced by genetic predispositions, and extrinsic ageing, or photoaging, which is brought on by environmental variables such as UV radiation, wind, relative humidity, pollution, and other factors. Age-related morphological, biochemical, and functional changes are superimposed on the effects of UV radiations on sun-exposed regions, allowing for a differentiation between the two phenomena. Using bioengineering technologies, cutaneous alterations brought on by ageing can be measured and monitored noninvasively. Age-related changes in skin elasticity, hydration, blood flow, and surface pattern reflect the harm done to the implicated cutaneous structures. The steady loss of skin elasticity seen with ageing is caused by the impairment and degeneration of elastic and collagen networks. Diminished stratum corneum water content and transepidermal water loss are the results of reduced blood flow and water delivery, likely due to faulty stratum corneum binding. Early indications of ageing can be identified by investigating morphological changes such as increased skin roughness, pigmentation, and altered skin surface pattern that start to occur after the age of 30.
