Our skin ages for a variety of different reasons. Many of the causes of skin aging are entirely natural and cannot be altered. There are, however, several factors that can cause skin to age prematurely, and these can be influenced. A holistic approach to lifestyle and skincare can help to reduce the visible signs of skin aging and prevent premature skin aging. The first noticeable signs of skin aging are fine lines and wrinkles. Small, shallow wrinkles known as laughter lines or crow´s feet tend to become noticeable at the outer corners of the eyes. These may appear around the age of 30, but we all age differently and how we age depends on our genetics and lifestyle. These fine lines are followed by wrinkles on the forehead. At first these are only visible when our skin moves as we change our facial expressions and they are known as dynamic wrinkles. As we age further they become more prominent and evolve into permanent wrinkles that are visible even when our face is static. Frowning can cause vertical lines between the brows.
