Improve muscle tone and skin elasticity by spending just a few short minutes a day doing these exercises. Practice in front of a mirror at first to ensure that you are not screwing up your eyes. 1. Open your mouth in an “O” shape. Drop your jaw downward very slowly to make an oval. Hold, feeling the stretch in your cheeks. 2. With your teeth together, draw the sides of your mouth outward, as if saying “eee.” Hold without wrinkling the skin around your eyes. 3. Pull the sides of your mouth upward into a wide smile. Hold, then pull them farther up. Hold, then release. Repeat 5 times.
