Although Botox isn’t a weight loss solution, undergoing a facial slimming treatment will give you the look of a slimmer, more angular facial structure. This is because this particular treatment targets the masseter muscles, a group of muscles that are usually targeted for facial slimming procedures. By using Botox injectables, the masseter muscles are reduced and creates a softer curved jaw. Depending on your facial structure, a few treatments may be required to achieve your desired shape. The procedure itself takes only a few minutes, with the results becoming evident throughout six weeks and lasts anywhere from six to twelve months.
