The Many Faces of Botox
Where Does Massage Fit?
BOTULISM- A BRIEF HISTORY
The first recorded case of botulism was in 1735, when a German physician documented an outbreak of dangerous, even deadly, paralysis that accompanied the consumption of a particular batch of contaminated sausages. He named this phenomenon, which turned out to be related to a bacterial infection, from the Latin botulus, which means ”sausage.”
Clostridium botulinum is a rod-shaped bacterium that doesn’t need oxygen to thrive, and it creates an environment-resistant shell called a spore. This allows it to be dormant for prolonged periods until it finds a friendly growth medium. These bacteria, which have several subtypes, secrete a substance that seeps into motor neurons at the motor end plate, and it blocks the secretion of acetylcholine altogether, leading to flaccid paralysis of the affected cells. The action of this toxin is permanent. The motor axon branches that are exposed will never secrete acetylcholine again, and the affected muscle cells are effectively out of commission until the neuron regenerates new terminating axons—a process that can take weeks or months.
A botulism antitoxin has been developed and can be used in cases where accidental botulism toxin exposure occurs. This can stop the progression of nerve damage, but not reverse it—whatever muscle power is lost will not be regained until the affected neurons regenerate their axon terminals. Advances in the understanding of this pathogen and its toxin, along with better attention to careful hygiene in food storage, means that botulism poisoning has become rare in this country, but about 100 cases of accidental poisoning are still reported annually.
BOTULISM TO THE RESCUE
The neurotoxin that causes the paralysis associated with botulism was first isolated in 1944. While it has been considered as a possible biological weapon, other uses have prevailed. A diluted and purified version of it was first used therapeutically in 1980 for strabismus—a condition involving the muscles that control eye movement. In 1989, the U.S. Food and Drug Administration (FDA) approved the use of Botulinum toxin for several muscle problems of the face and neck. In 2002 the FDA approved the use of botulinum toxin for some other conditions, as well as for cosmetic uses—it can temporarily paralyze the muscles of facial expression that cause wrinkles. From that time, the industry grew fast, and some subtypes of the laboratory-prepared material have now become available. The most common trade names are Botox, Botox Therapeutic, Dysport, and Myobloc. Some preparations of botulism toxin have slightly different effects from different conditions, and the dosing guidelines are unique to each brand—they are not interchangeable. Consequently, in 2009, the FDA issued “black box” label warnings so professionals would use these products with great care.
WHAT IT IS USED FOR
Botulinum toxin is used cosmetically to address glabellar lines (those are formed by forehead muscles that pull the eyebrows together in a frown), and to reduce tone in other facial muscles, specifically the corrugator and procerus muscles. The net result is a face with a reduced appearance of wrinkles, brought on by induced flaccid paralysis of the key muscles. It typically takes three to six months for the affected neurons to grow new axon terminals, at which time control of the muscles is restored.
In addition, the toxin is approved for use to treat the following conditions:
- Strabismus. This condition involves asymmetrical tone in muscles that move the eyeballs. The result is sometimes called “lazy eye” or “crossed eyes,” and the pupils are not parallel. Botulinum toxin can equalize the muscle tone between the eyes.
- Blepharospasm. This condition in which the orbicularis oculi muscle involuntarily contracts. It may be a part of several different types of dystopia, and it can lead to functional blindness, even though the eyes themselves are not affected.
- Hemi facial spasm. This unilateral involuntary contraction of the muscles of the face can be related to a cranial nerve irritation, a tumor, or unknown factors. Botulinum toxin prevents the contractions.
- Cervical dystopia. Also called spasmodic tort Collis, condition involves painful unilateral involuntary contractions of the sternocleidomastoid and other neck rotators.
- Vocal dysphonic. This involves involuntary contractions of the muscles that control the vocal cords, leading to problems with speech.
- Migraines. Chronic migraine appears to respond well to injections of botulinum toxin. It has also been studied for chronic tension-type headache, but the results were not consistently better than alternative options.
- Maxillary and palmer hyperhydrosis. Multiple tiny injections to the skin where sweat glands are overactive can reduce sweating for several months at a time.
- Muscle-related pain. People who have pain related to involuntary spasm can benefit from injections that limit muscle tone. New research and manipulation of the toxin holds promise for other pain-related applications as well.
BOTOX & MASSAGE—ALLIES OR ADVERSARIES?
Most applications of botulinum toxin occur without major adverse side effects, but while complications are rare, they are not unheard of. According to the FDA, symptoms of botulism poisoning can occur if the treatment protocol is wrong, or—and here is where massage therapists should be alert—if the solution seeps out of the intended treatment area.
The promotional material distributed for cosmetic applications of Botox suggests that the full effect of cosmetic injections may not be achieved for several days after treatment. The patient is encouraged to gently exercise facial muscles immediately, but not to touch, compress, sleep on, or otherwise disrupt the injection sites for a minimum of four hours after treatment, in order to avoid spreading the toxin to unintended areas. This includes facial manipulation with massage as well, and massage elsewhere on the body must be conducted without putting the client face down in the cradle—otherwise the post massage “table face” that many of us experience may last a lot longer than usual.
So it seems clear that massage and Botox are not good partners, because manipulation of treated areas may decrease the desired action at the targeted spot and increase undesired action in surrounding tissues. This makes sense for cosmetic applications. However, some research suggests that the toxin, when injected into deeper muscles, may work better if the tissues are carefully manipulated to improve its uptake. For our clients who use Botox for therapeutic rather than cosmetic purposes, this could be very significant. Unfortunately, this also appears to be the situation with the highest chance of adverse effects. The people documented to be most at risk have been children with cerebral palsy and other patients who use the toxin for deep muscle applications at the extremities, rather than for head and face issues. Some patients with cervical dystopia or vocal dysphonic also experience problems with swallowing after treatment. This can be dangerous, because it allows the aspiration of material into the lungs that can lead to life-threatening infection.
Where does all this leave the massage therapist in the spa and the other one in the clinic?
The spa therapist has guidelines that are fairly clear: no facial massage on the day of injections, and no prone work either—any massage must be conducted without putting pressure on the face. That client can receive massage as usual when the full effect of the Botox treatment is achieved, which may take several days.
For the clinical therapist, the guidelines are murkier. Questions that need to be answered include: Where was the injection, and what condition was it for? How recent was the treatment? Should she work deeply on the injection sites to help the toxin be more effective? Should she avoid the area to reduce the risk of an adverse reaction? What kinds of adverse reactions are possible?
In this situation, we are in largely uncharted territory, but we are not here alone. With the client’s permission, it is possible to work closely with the neurologist or other specialist who administers the injections and to follow up with the client to track results.

The JuicePlus Vineyard blend has CQ10 and niacin. It strengthens collagen and elastin. The blueberries in the JP Vineyard blend contain oxidants that fight free radicals that attack healthy skin cells. JP increases skin cell density, creating healthier new skin cells. JP leads to better hydration, so wrinkles are less visible. JP increases microcirculation, which improves skin color and skin tone.
