This injectable product is designed to work on the facial lines that are the result of repeated facial movements that will cause the skin to furrow and fold and lead to the eventual formation of a more permanent facial line. BOTOX works beneath the skin’s surface to temporarily reduce the contractions of the underlying muscles, from which a groove is formed in the skin, to help them appear visibly smoother. The concept of slowing down muscle activity can also be applied to the condition of excessive sweating (hyperhidrosis) to stop the vast amount of sweat that the sebaceous glands produce. In cases of migraines and chronic headaches, BOTOX works in the same way to stop the nerves from sending pain signals to the brain, thus relieving the painful headaches.
