Botox is used medically to remove fine lines and wrinkles by temporarily paralyzing muscles. This is done by injecting extremely small concentrations which prevents signals from nerve cells to reach the muscles thereby paralyzing them. There are few side effects like mild pain and swelling.
Visible improvement occurs within 3-10 days of injection and lasts for 3-6 months. Natural looking results are achieved by using the right amount injected into the right area.
