The vertical lines between the eyebrows are the direct result of repeated muscular action of the muscles of facial expression. Years of squinting and frowning leave deep wrinkles in the skin between the eyebrows. After many years of frowning combined with the weathering action of the sun, the skin is left with deep vertical lines, which are there even when the face is at rest. You look like you’re mad even when you’re not. The laugh lines around your eyes and those on your forehead are often caused by your expressions, as well as sun damage. There has never been a satisfactory solution to these problems until Botox. Once Botox has immobilized the muscles for several weeks, many of the noticeable lines between the eyebrows, on the forehead or around the eyes may relax and become less noticeable.
