Guide to Botox©
Dr. Jeffrey Harmon
A Brief History of Botox©
Research on the use of botulinum toxin (e.g. Botox©) for therapeutic purposes began in the 1960s for patients with strabismus, or “cross eyes.” It was first FDA-approved for therapeutic use on strabismus in 1989. It was not until 2002 – thirteen years later - that the FDA approved Botox© for cosmetic use. It was first approved for cosmetic use between the eyebrows, also known as the glabella or “eleven lines.” Botox© was then approved for additional areas (underarms, crow’s feet, and forehead) over the next 15 years. Other botulinum toxin products (Xeomin©, Dysport©, Jeuveau©) gained approval for cosmetic use in that period as well.
How Botox© Works
Botox© is delivered at much lower doses for therapeutic and cosmetic purposes than exists naturally. However, its mechanism-of-action is the same. It works at the junction between the muscle and nerve that signals the muscle to contract. Botulinum toxin binds to a terminal at the end of the nerve and prevents the release of molecules that would otherwise signal the muscle to contract. Its effects wear off as the body gradually breaks down and replaces these proteins.
The treatment is effective for dynamic rhytids, or coarse wrinkles that develop when we move our faces. When evaluating the effectiveness of any treatment it is best to find the highest quality studies, which are generally randomized controlled trials (RCTs). Even better are studies that combined the data from multiple RCTs. The Cochrane Library is the gold-standard source of medical research. However, it is not always possible to find research on any subject you desire in this database because of the immense work involved studying each question. Fortunately, The Cochrane Library has published on the effectiveness of botulinum toxin in a paper entitled “Botulinum Toxin Type A for Facial Wrinkles.” They evaluated 65 RCTs that included a total of 14,919 patients. Injection of botulinum toxin in the glabella was compared with placebo. Results ranged from 4 weeks to 2 years after treatment. They concluded that botulinum toxin is likely effective at week 4 after treatment, which is an important finding.
Its effectiveness is reflected in its ubiquity. Botulinum toxin was the most popular non-surgical cosmetic procedure worldwide in 2020 according to statistics compiled by the International Society of Aesthetic Plastic Surgery (ISAPS), with approximately 6.2 million injections performed. The most common age range to receive injections was 35 – 50 years.
Common Questions About Botox©
A common question is whether Botox© administration is painful. A 31-gauge insulin needle is used, the smallest needle size available in clinic. As a result, treatment is generally associated with little-to-no pain.
Another common question is whether Botox© administration is safe. The answer is yes in a significant majority of cases. Its approval by the FDA is an endorsement of its overall safety profile. The best way to evaluate the safety of Botox© treatment is to review both the highest quality data (i.e. RCTs) but also the Adverse Event (AE) reporting to the FDA that occurs whenever a medication is approved for use by the FDA. A 2005 study of FDA-reported AEs associated with botulinum toxin type A used for both therapeutic and cosmetic purposes demonstrated the vast majority of reported AEs at the time were labelled “non-serious,” with 63% of those AEs being a “lack of effect,” 19% involving an injection site reaction (e.g. pain, bruising, swelling, allergic reaction), and 11% involving eyelid ptosis, or a drooping eyelid, which is a temporary possible risk that can be decreased with appropriate technique. A significantly smaller percentage of AEs were labelled as “serious,” the most common of which was swallowing difficulties. It is important to note, however, that reported AEs included injection of botulinum toxin for neck banding, which is in an area very close to muscles that contribute to swallowing. That could explain the above reporting. Moreover, a large majority of AEs reported with botulinum toxin administration were for therapeutic use (e.g. strabismus), not cosmetic use. It is suspected that serious AEs are likely related to both the amount used and the location it is used. Therapeutic uses involve much higher doses than cosmetic uses and are placed in areas with a higher risk of functional problems.
Assessing individuals for possible contraindications and appropriate counseling and informed consent is essential. It is very important to evaluate patients who may not be good candidates for the medication. One example is patients with a history of neuromuscular disorders, including Myasthenia Gravis (MG) and Lambert-Eaton Syndrome (LES). Pregnant and/or nursing mothers should not receive it. Patients actively taking aminoglycoside antibiotics or streptomycin should not receive it because the antibiotics could potentiate the effects of the medication.
Dr. Harmon has a detailed discussion of the potential benefits and risks of injecting Botox© with every client who is interested in treatment. As a fellowship-trained facial plastic surgeon, he has the detailed understanding of facial anatomy necessary to provide these treatments safely and effectively.
