I f we look at skin that has only endured normal intrinsic [within the body] or chronological [getting older!] ageing, it is smooth and generally unblemished. There may be exaggerated expression lines but, by and large, the skin is well preserved. Under the microscope, we will see some signs of ageing, which include a flattening of the epidermal-dermal connection and some breakdown of the dermal tissue. In direct contrast, extrinsically [environmental and other external factors] aged skin such as that found on our face, hands and chest is wrinkled, sallow in colour and has areas of hyper — and hypo-pigmentation. Skin may show a loss of tone and elasticity, increased fragility, areas of purpura [purplish discolouration of the skin produced by small, bleeding vessels near the surface caused by blood vessel weakness], and benign lesions such as keratoses, telangiectasis and skin tags. Again under the microscope, discreet changes are evident in the collagen and elastin, which are now fragmented and thick, indicative of the cross-linking that is associated with wrinkle formation. Scientists have found more modern ways to address the issue of wrinkles, skin discoloration, the breakdown of collagen and elastin, dehydration and the slowdown of cell turnover through understanding the biochemical reactions that trigger these structural changes. Wrinkles Wrinkles are depressions in the skin’s surface that may be coarse or fine, depending on their depth. Depth may extend from a few micrometres to several millimetres. Coarse wrinkles, often referred to as “expression lines”, appear on the forehead, outer corners of the eyes (crow ’s feet) and as vertical lines on either side of the mouth (laugh lines). Fine wrinkles are the shallower network of lines or indentations that appear on our skin, especially in areas of facial movement (such as the eyes, mouth, upper lip and so forth). Wrinkles occur as a result of: • A reduction in muscle mass and skin thickness. • Cross-linking of collagen and elastin in the dermis. • Dehydration of the strat um corneum. This results in visible wrinkles on the surface of the skin and a loss of mechanical strength and elasticity. Skin Discolouration Changes in skin colour are often associated with ageing. Skin colour is a composite of red, blue, yellow and brown colouration. This is the result of red oxygenated haemoglobin, yellow carotenoids and flavins and the brown melanin pigment of our skin.
