The Outward Signs of Aging Skin
Decreased skin elasticity (sagging skin and wrinkles) is the hallmark sign of aging skin. Skin primarily consists of two proteins, collagen and elastin. Collagen’s three stranded helical shape is what consists of the skin’s strength, firmness, and elastic properties. Elastin, by virtue of its name, contributes most to the skin’s elasticity. It allows skin to quickly return to its normal position after it has been depressed or pulled out of place.
As skin ages, it takes longer to return to its normal position. The ability of collagen and elastin to function properly declines with age. This is due in large part to one’s genetic makeup. However, there are some behaviors that accelerate loss of elasticity, skin sagging, and wrinkles. These include smoking, exposure to U.V. radiation, stress, insufficient sleep, and a high sugar intake. Even if one leads a healthy lifestyle by staying out of the sun, not smoking, avoiding stress, getting eight hours of sleep every night, and never eating refined sugars, one still has to contend with her genetic composition.
Aging skin also reveals shrunken capillaries which result from arteries clogged with cholesterol and calcium deposits. Arterial flexibility throughout the body decreases with age, and there is compromised blood flow to the periphery, particularly to the skin. Reduced blood flow means less oxygen and nutrient delivery to the skin. A healthy diet packed with antioxidant rich fruits and vegetables will not be as beneficial if the vitamins and minerals cannot reach the skin cells.
