How Does Botox® Work?
Botox® injections contain a product called botulinum toxin, which is the solution that gets injected precisely into your face. When this toxin is injected, it will disrupt the way that nerve signals pass between your brain and muscles. Specifically, it makes it harder for the brain to signal to the muscle to contract. This forces the muscle fibers into a state of relaxation, preventing them from making any slight movements.
Usually, Botox® is injected into areas of your face that are prone to form lines or wrinkles from facial expressions. For example, you can get wrinkles on your forehead from frowning too often. Botox® will target the muscles that make you frown, stopping them from contracting. In turn, this can reduce the appearance of wrinkles as your skin isn’t constantly folding while you frown.
How Safe is Botox®?
Adding toxins to your body is normally viewed as a negative thing – particularly if said toxin disrupts nerve signals. Yes, large doses of botulinum toxin can be dangerous and harmful. However, Botox® only contains a very small dosage of this toxin and it has been rigorously tested and approved for use by the FDA for decades.
In fact, very few people see any side effects at all from Botox® injections. Those that do will usually only experience mild headaches or some slight swelling or bruising. In the vast majority of candidates, Botox® won’t have a negative effect or cause any substantial nerve damage.
