Anti-wrinkle injections treat wrinkles caused by the contraction of facial muscles. They inhibit the signals from the nerves to the muscle, and stop the muscle from contracting too much and forming wrinkles. For example, injections can be used to relax the muscles around the eyes to prevent the appearance of crow’s feet.
Anti-wrinkle injections help to relax certain muscles in the face that cause wrinkles and they are most frequently used on frown lines, crow’s feet, and forehead lines to create a refreshed look.
