Collagen, wrinkles, and ageing skin

Collagen is a protein that plays a crucial role in maintaining the structure, firmness, and elasticity of the skin. As we age, several changes occur in the collagen of our skin, contributing to the visible signs of ageing, such as the appearance of wrinkles. Here are some key aspects of how collagen changes with age: Decreased Production: The synthesis of collagen decreases with age, leading to a reduction in the overall amount of collagen in the skin. This reduced production is influenced by both genetic and environmental factors, such as sun exposure and lifestyle choices, like smoking and alcohol consumption. a balanced diet rich in vitamins and minerals, can have a positive impact on collagen production. Degradation: Collagen fibres can undergo degradation due to various factors, including exposure to ultraviolet (UV) radiation from the sun, pollution, and other environmental stressors. Enzymes called matrix metalloproteinases (MMPs) play a role in breaking down collagen. This is heightened by exposure to sunlight and pollution. Antioxidants from our diet can help combat the effects of environmental stressors on collagen degradation. Cross-linking: Collagen fibres undergo a process called cross-linking, where they become more rigid and less flexible. This can result in the loss of skin elasticity and the formation of wrinkles and fine lines. Excessive cross-linking is often caused by factors like prolonged sun exposure. Changes in Collagen Types: The composition of collag...
