The skin naturally loses elasticity and becomes more fragile the older a person gets. The fat amount in the face lessens, which causes the skin to sag and increases the appearance of lines. Ultraviolet radiation from the sun breaks down collagen and elastin fibers in the deep layers of the skin to decrease its flexibility and cause premature wrinkles. It is good practice to apply a sunscreen with an SPF of at least 30 every day, even if a person is only outside for a few minutes. Wrinkles from smoking may be caused by changes in the blood supply in the skin. Repeated squinting and smiling cause wrinkles as the skin loses its ability to spring back into place as it ages. Drinking alcohol dehydrates the skin and makes it lose its elasticity. Alcohol also depletes the vitamin A level in the body. Vitamin A regenerates skin cells and is important in collagen production. Eating foods high in sugar causes sugar molecules to attach to the skin and make it stiff, which then causes fine lines and loss of elasticity. Refined sugar and simple carbohydrates tend to raise insulin levels, which causes inflammation. The inflammation breaks down collagen and elastin.
