Recently, there have been concerns about retrograde botulinum toxin transmission, meaning that the toxin could travel back to the central nervous system, causing long-term damage. Studies done in Italy by Flavia Antonucci have been mainly on a raw form of the toxin and not any of the commercially available preparations. Additionally, these studies have been performed on animals and with the injection of the toxin to one area and in a concentration of nearly 150 times greater than normal injections for cosmetic indications, which are spread over multiple sites.
According to the PREEMPT injection paradigm, a total of 5 units of onabotulinumtoxinA is injected into each corrugator muscle. To confirm the location of the muscle, the patient is asked to furrow the brow in order to activate the corrugator. Once the muscle has been located, the muscle should be palpated and pinched by holding it between the thumb and index finger. Five units of onabotulinumtoxinA is injected at an approximate 90° angle with the bevel of the needle pointing upward into the medial belly of the muscle. As the needle is inserted, there is skin resistance, which lessens when the muscle is penetrated. This decrease in resistance is termed a muscle pop. Once the muscle pop occurs, inject into the superficial muscle. If the injection is too far superior or above the corrugator muscle, brow ptosis can occur due to depression of the medial brow as the frontalis elevating function is lost and the corrugator depressing function remains unopposed. Whereas weakening the corrugator muscle will cause elevation of the medial eyebrow, alternatively, if the corrugator injection is done too low, then diffusion to the levator palpebral muscle could lead to lid ptosis.
The best part of Botox is people saying that you look great, but they can’t put their finger as to why. When administered effectively, you’ll look like a brighter, smoother version of yourself, but not plastic-y. To prevent looking frozen, Dr. Tutela says to make sure your dermatologist or plastic surgeon tells you how many units they recommend. Everyone’s face is different and again, there is no magic number, but knowing your starting point will help tailor future appointments, he says. And don’t do anything until you learn the 13 things plastic surgeons will never tell you.
Postmarketing reports indicate that the effects of BOTOX and all botulinum toxin products may spread from the area of injection to produce symptoms consistent with botulinum toxin effects. These may include asthenia, general ized muscle weakness, diplopia, ptosis, dysphagia, dysphonia, dysarthria, urinary incontinence and breathing difficulties. These symptoms have been reported hours to weeks after injection. Swallowing and breathing difficulties can be life threatening and there have been reports of death. The risk of symptoms is probably greatest in children treated for spasticity but symptoms can also occur in adults treated for spasticity and other conditions, particularly in those patients who have an underlying condition that would predispose them to these symptoms. In unapproved uses, including spasticity in children, and in approved indications, cases of spread of effect have been reported at doses comparable to those used to treat cervical dystonia and spasticity and at lower doses.

Botox can be bought by essentially any person with a DEA certificate. Allergan sells it in 50 and 100 unit vials. They are shipped overnight delivery on dry ice to keep the toxin effective it should be opened, reconstituted and used the same day ideally. The Botox will work best this way. Price points will change by who the injector is and what their motives are. Botox can be reconstituted so that you getting a very dilute amount of product. So a by the area approach may really only give you a small amount of product. Or you could be getting old Botox that is a week old and will not last for very long.
In both studies, significant improvements compared to placebo in the primary efficacy variable of change from baseline in wee kly frequency of incontinence episodes were observed for BOTOX (200 Units) at the primary efficacy time point at week 6. Increases in maximum cystometric capacity and reductions in maximum detrusor pressure during the first involuntary detrusor contraction we re also observed. These primary and secondary endpoints are shown in Tables 21 and 22, and Figures 7 and 8.
Botox is a drug made from a neurotoxin produced by the bacterium Clostridium botulinum called botulinum toxin. "It's a poison secreted by the bacteria," plastic surgeon Norman Rowe, M.D., tells SELF. Botulinum toxin has proven to be a successful and valuable therapeutic protein when dosage, frequency of treatment and variety of treated clinical conditions are considered, according to Howard Sobel, M.D., a dermatologist in New York. Basically: when it's done right. When it's done wrong—like, really, really wrong—it can cause "botulism-like symptoms," according to Mayo Clinic, which may include muscle weakness, trouble breathing, speaking or swallowing, bladder control issues, and vision problems. That is "very unlikely," but a more than convincing enough reason not to go bargain hunting for Botox.
Cornea problems have been reported. Cornea (surface of the eye) problems have been reported in some people receiving BOTOX® for their blepharospasm, especially in people with certain nerve disorders. BOTOX® may cause the eyelids to blink less, which could lead to the surface of the eye being exposed to air more than is usual. Tell your doctor if you experience any problems with your eyes while receiving BOTOX®. Your doctor may treat your eyes with drops, ointments, contact lenses, or with an eye patch.
