Its primary function is to temporarily relax overactive facial muscles, which helps smooth out dynamic wrinkles such as forehead lines, frown lines between the eyebrows, and crow’s feet around the eyes. Beyond wrinkle reduction, BTX has several additional aesthetic benefits. It can subtly lift the brows, refine the jawline for a slimmer, more balanced facial contour. It can also soften a gummy smile, improve the appearance of chin dimpling, and create a more harmonious facial expression overall. In some cases, BTX is used for non-cosmetic purposes, such as reducing excessive sweating (hyperhidrosis), managing tension headaches, or treating teeth grinding (bruxism).
