If you are going to have Botox injections to get rid of your wrinkles it is a good idea to understand how they work – and how your facial muscles work. Botox is mainly used to treat wrinkles in the face, but it may not be suitable for all kinds of wrinkles.
How wrinkles form
Wrinkles form due to the action of muscles moving the skin, but those wrinkles form perpendicular to the muscles that causes them. For instance, those mainly perpendicular lines between your eyebrows are cause by a horizontal muscle contracting, while the horizontal wrinkles above your eyebrows and across your forehead are caused by the contraction of a vertical muscle.
How Botox prevents them forming
When Botox is injected into the muscle it blocks the nerve impulse to tissues and thus prevents it from contracting or moving and this is what removes the wrinkles. If muscles cannot move, then they can’t push the skin into a fold or wrinkle. The muscle may still be able to move a little bit, especially as the Botox is absorbed into the body and loses its effectiveness.
