Wrinkles on the forehead can give the face an older, more haggard appearance. As people age, the muscles used to form facial expressions create permanent creases in the skin. One of the benefits of Botox injections is that they can be used to relax the facial muscles, resulting in smoother skin and fewer wrinkles. In areas such as the forehead, where horizontal wrinkles tend to form, the Botox benefits are particularly valuable. Contrary to the common misconception that a doctor must treat each wrinkle, only the underlying muscles that cause wrinkles must be treated. Once you have received your Lexington Botox treatment, the muscles that ordinarily cause wrinkles and lines to appear in the forehead are no longer as active for a period of several months.
