People spend billions of pounds every year trying to get rid of lines and wrinkles because they are one of the things we most associate with getting older. As our faces age we age we lose collagen and elastin in our skin and this, combined with the effects of time and gravity, as well as lifestyle factors, causes our skin to wrinkle. Some wrinkles appear as small, fine lines while others create deeper ridges or folds, also known as “furrows”. Wrinkles can either be “dynamic” in that they are caused by facial movement and may only be visible when moving the face, or “static” where they are caused by loss of elasticity in the skin as well as outside factors such as the sun or smoking and are visible even when you are not moving your face. Some dynamic lines may eventually become static, in that they are visible even when you are not moving your face. This is particularly true of crow’s feet, also known as laughter lines, and smoker’s lines.
