when you have your closed ones a big surprise and the way they reacted. I can bet that the look on their face would be worth a million dollars! Facial expressions help us express better, and also helps us in judging as to what one might be thinking. But, what we do not know is that while we express, our muscles contract, and repetitive expressions for years contract the muscles which makes the lines very noticeable and gradually quite prominent. With age, the skin loses its ability to spring back, and hence the lines get prominent. So, next time, try not squinting or frowning unnecessarily.
