Dynamic wrinkles are the creases we normally see around the eyes, forehead and frown area. These are the signs of aging caused by years of making facials expressions such as smiling, laughing and frowning.
When we’re young our skin is supple and has excellent elasticity. Few lines are visible or they disappear completely as soon as we stop making facial expressions. As we get older, however, facial wrinkles remain visible even when our face is at rest. These are called static lines.
Neuromodulators or “anti-wrinkle injections” work by temporarily blocking the communication between nerve cells, preventing facial muscles from contracting. As the muscles relax, the skin takes on a smoother and more youthful appearance.
In most cases, neuromodulators work best on dynamic lines and wrinkles. Although with regular use, even static lines can improve over time, becoming softer, less visible.
