Skin ageing is a complex process influenced by a combination of intrinsic (internal) and extrinsic (external) factors. Understanding these factors is crucial for developing strategies to prevent and treat skin ageing.
Intrinsic factors are primarily determined by genetics and biological processes that occur naturally as we age.1
Genetic predisposition plays a significant role in determining how quickly and how severely an individual's skin will age.2 Changes in hormone levels, such as a decrease in oestrogen during late perimenopause and after menopause, can lead to reduced collagen production and skin thickness.3 Ageing related cellular damage which occurs over time can also lead to a decline in skin cell turnover and function.4
Extrinsic factors refer to environmental and lifestyle-related factors that accelerate skin ageing.2
Aged skin has fewer cells like fibroblasts which make your scaffolding tissues like collagen and elastin fibres.5 Reduced collagen and elastin causes sagging skin, fine lines and wrinkles.6 This lack…
