When looking surprised or when moving the forehead to make facial expressions, horizontal lines can develop in the skin. This can sometimes give a worried look. The forehead muscles that are continuously raised can also give a tense feeling or even headache. With a wrinkle relaxer, the lines of the forehead can be softened and so can the appearance. An additional effect can also be that you’ll get headaches less often or they can entirely go away because there is no more tension on the forehead. Often the forehead is treated in combination with the frown.
