What is Skin Ageing
Skin ageing is a complex biological process influenced by chronological ageing, photo-ageing, hormonal deficiencies, and environmental factors. These factors collectively cause structural and physiological changes in the skin. The process involves a reduction in the number of fibroblasts that produce collagen and vessels that supply the skin, leading to increased laxity and the formation of wrinkles. Skin ageing is a result of mechanisms such as glycation, free radicals, cell cycle changes, and cellular and molecular processes.
Types of Skin Ageing
Skin ageing is broadly classified into two types: intrinsic and extrinsic ageing. Both types of ageing contribute to the overall deterioration of skin quality, leading to wrinkles, fine lines, and other signs of ageing. This distinction helps in formulating targeted strategies to address specific ageing concerns and promote overall skin health
Intrinsic Ageing of Skin
Intrinsic skin ageing is a natural, genetically determined process characterised by physiological changes that occur over time. It primarily reflects the genetic clock and metabolic processes within our bodies. This type of ageing begins in the mid-20s and is marked by a gradual decline in collagen and elastin production, leading to a loss of skin fullness and elasticity.
As we age, our skin also becomes thinner and drier, making it more prone to cracking and sagging. These changes contribute to the development of wrinkles and other signs of intrinsic ageing, particularly noticeable in photoprotected areas, such as the inner side of the upper arm.
