Yes. As the muscle moves up, lifting the eyebrows, the skin creases in horizontal folds as the skin becomes redundant. By relaxing the muscle with Botox, the skin doesn’t move up as much and the creases disappear slowly. Botox minimizes the movement of the forehead muscle to decrease the horizontal lines.
If one’s age has allowed the forehead to droop significantly, it can lower one's upper eyelids. Many people with this condition use their forehead muscles to keep their eyelids open more, and do this without realizing it as a habit. In that case, Botox would be avoided as it could block one’s use of the muscle and the eyelids would droop.
