Skin wrinkles are generally caused by a breakdown of the collagen framework within the skin.
Collagen is a key part of your skin's structure. It forms a network of fibers within your skin that acts like a framework.
In young skin, the collagen framework is intact and the skin remains moisturized and elastic. Over time, the support structure weakens and the skin loses its elasticity. The skin begins to lose its tone as the collagen support wears down.
Wrinkles and other signs of skin ageing can be influenced by habits and behaviours during a person's life. Avoiding some risk factors for premature skin ageing can help keep skin looking younger for longer.
