Botox® is a trade name for botulinum toxin, which comes in the form of a purified protein. Botulinum toxin A is the most commonly used form with a few thousand articles supporting its use in scientific and medical literature. The mechanism of action for botulinum toxin A is really quite simple. It is injected into the facial muscles and, within a few hours, it attaches itself to the nerve endings of the motor muscles, thereby affecting the nerve transmission to these muscles. It takes anywhere from two to ten days to block the nerve transmitters which innervate the muscles where it was injected. There is no loss of sensory feeling at all during the time that botulinum toxin A is effective. Once these motor nerve endings are interrupted, the muscles cannot contract. When the muscle does not contract, the dynamic motion that causes wrinkles in the skin will then cease. The only reason there are wrinkles in the skin in the first place is because the muscle is moving underneath it, thereby these are called dynamic wrinkles. Approximately three to ten days after treatment, the skin above these motor muscles becomes nice and smooth. The effects of botulinum toxin lasts approximately three to four months depending on various factors including the amount of botulinum toxin A injected, metabolic activity of the patient and lifestyle choices, which may cause the botulinum toxin treatment not to last as long. When the patient sees the wrinkles reappear, the patient needs retreatment.
This is one of the reasons that Botox® has such an incredible safety record. Botulinum toxin A treatment by its nature is a temporary treatment and when the treatment effects are gone, they are gone completely.
Frown Lines form over time. Repeated movement of the facial skin by the muscles creates frown lines between the eyebrows. Frown Lines are not only age related. Frown lines are dynamic they happen because of the way a person’s face moves. Because frown lines are created by facial movements such as frowning or squinting, they may develop even in younger adults. The muscles above and between the eyebrows contract and tighten, and can cause wrinkles. Botulinum toxin blocks the nerve signal that causes these facial muscles to contract. This results in a reduction of muscle activity in the treated area and temporarily stops the contraction of these muscles. botulinum toxin restricts muscles. If you are to restrict the group of muscles that cause eyebrow depression, you can achieve a brow lift. Using botulinum toxins as a means for achieving a brow lift is one of its more common uses. Proper botulinum toxin training is a must for patients when choosing a facial esthetic practitioner.
