Developing lines and wrinkles in the skin as we get older is a concern that almost everyone will experience to some degree. Often one of the more noticeable sets of creases are frown lines, that appear as small vertical lines between the eyebrows. Also known as ‘eleven lines’ or ‘glabella lines’, frown lines can often become deeper and more noticeable with time, giving the affected person an angry or stressed look which isn’t befitting of their true nature.
