HOW CAN SKIN AGE?

Intrinsic ageing or Chronoageing: This refers to the physiological, clinical and histological changes that come about in the skin with advancing age. Skin that is aged intrinsically is characterised by a lack of tone and fine lines. It is essentially characterised by loss of its maximum functionality ability and an increase in vulnerability to certain pathological processes and environmental factors.
Extrinsic ageing: These are the physiological, clinical or histological changes that take place in the skin as a consequence of the aggression of external factors such as exposure to the sun, tobacco or exposure to the elements. Traditionally, the most exposed areas of our body are those that show the greatest degree of extrinsic ageing: face, hands and neckline. Rupture of the collagen fibres and elastin bridges is very characteristic of photoaging in the dermoepidermal plane, at the expense of the harmful action of free radicals on the cell membrane and on a mitochondrial level, altering the properties of the extracellular matrix.
