Although we can control our exposure to certain factors that cause fine lines and wrinkles, reduction in collagen is a natural process that none of us can escape. As we age, there is a decrease in collagen production and a subsequent loss of elasticity. Collagen is a structural protein that acts as a main component of connective tissue, giving skin its plumpness. As its levels diminish, the skin loses its fullness, becoming thin and papery. Over time, the skin’s elasticity – its ability to be stretched and bounce back to its original position – also decreases, resulting in sagging skin that often folds and creases. Habitual facial expressions such as squinting and raising your eyebrows also contribute to wrinkles.
Environmental factors that contribute to fine lines and wrinkles as well as premature ageing include sun exposure (without appropriate protection), smoking, poor diet, alcohol consumption, and even pollution.
