What causes wrinkles?
Natural substances in our body, such as collagen (the major protein in our body which gives structure to skin)
and hyaluronic acid (a substance that gives our skin volume) decrease with age, giving rise to wrinkles. In addition,
elastin (another natural substance in our body which allows our tissue to stretch) also decreases in volume, so skin
loses its elasticity. When pressed, it no longer springs back and instead, sags and forms wrinkles.
The ability of our skin to retain moisture diminishes, sweat glands degenerate, so our skin loses its natural moisturiser.
As we get older, our skin cells divide more slowly. The ability of skin to repair itself diminishes with age, so wounds are slower to heal.
Persistent muscle contraction leads to frown lines between the eyebrows and crow's feet which start at the corners of our eyes. Habitual facial expressions also form characteristic lines.
The skin can also age prematurely as a result of prolonged exposure to ultraviolet (UV) radiation from sunlight. Other environmental factors, such as cigarette smoke and pollution, may hasten aging by producing free radicals. Free radicals can damage cell membranes & interact with genetic material. This may contribute to a number of skin conditions, including wrinkles & skin cancer.
Antiaging skin care is designed to fight some of these skin aging processes and to reduce wrinkles.
