Wrinkles and fine lines are the main signs of ageing on the skin, caused by the reduction of collagen and elastin in the skin as a person ages. As skin becomes less elastic, it can start to develop lines and wrinkles when certain expressions are made.
However, it isn’t only the natural ageing process that can cause unwanted lines and wrinkles. Smoking can speed up the natural ageing process of the skin and also cause fine lines around the mouth area, while sun exposure can cause damage to the skin and lead to the formation of lines and wrinkles. It’s also possible for wrinkles and lines to appear with frequent repetitive facial expressions such as smiling, frowning and squinting.
