Every day, our faces go through a workout as they express our emotions and communicate non-verbal messages to other people. To make these expressions, certain facial muscles need to contract; over time, these repeated expressions form lines on our skin that don't go away even after the expression is gone. These lines can make us look older and worn out. Botox injections temporarily paralyze the targeted facial muscle or muscles that cause facial wrinkles to form. After a Botox treatment, you can expect to look years younger, with smoother, firmer skin creating a wrinkle-free, yet natural-looking, facial appearance.
