Now, thanks to Botox, unwanted wrinkles such as worry lines, frown lines, and crow’s feet can be a thing of the past - all without the need for painful surgery or a prolonged recovery period. Botox is used in a procedure known as Cosmetic Denervation to relax the overactive facial muscles responsible for prominent expression lines such as worry lines, frown lines, and crow’s feet. Botox dramatically improves the appearance of these lines by blocking the nerve impulses to these overactive muscles, making them unable to contract. As the muscles relax, the lines disappear. Desirable facial expressions remain unaffected. Botox does not affect sensory nerves, so there is no numbness in the area of the injection.
