Can Botox cause death? What exactly happened!
It is a sad and unfortunate week for all those practicing Aesthetic & Dermatology. There has been a report of a case of death who was a property agent following Botox in Singapore and there has been much debate and worries regarding this procedure. There also has been any questions arising from some of my current patients. There has also been a few articles from some doctors in Singapore writing on this Botox Death topic so I shall not go though too much technical details.
Although there has been no official report yet on the exact cause of death, let's go through Botox itself as a procedure and drug and if it can really result in death!
Botulinum toxin is the most common cosmetic procedure performed world wide with an estimate of nearly 3 million injections per year. It works by the action on muscle nerve endings to disturb the transmission of information preventing these muscle from contracting resulting in them being temporarily paralysed.
Hence it would be logical based on how Botox works to say that Yes, Botox can cause death.
But of course as with all things, how much Botox do you need to be causing death and was this what was done in this case?
Studies have shown that a dose of of more than 6 U of botulinum toxin/kg used in children and other medical indications may cause death. [1] A female that weights about 50kg needs to receive almost 300U of botox.
A typical total amount of units for the forehead would be either 8 or 16 units. Crows feet? Maybe 4 units per eye or 12 units per eye.
Jaw muscles, the most I usually use is about 80 units.
As Botox's function is to paralyze muscles, less muscle contraction would lead to better wrinkles. Less muscle contraction would also lead to smaller jaw muscles and hence a more V shape face.
Botox can also be used for lifting with a unique technique called Dermalift. But the dosage used in these is also so low. No way even close enough to result in a Botox Death as what the news claimed.
How can anyone possibly be reaching such high levels of above 300U of Botulinum Toxin if this was done only for aesthetic reasons?! So in order for someone to be using THAT much Botox, it has to be done for medical reasons. But was this the case?
There has been reports in 1990s of people actually having consumed or eaten Botulinium Toxin. As this was produced by a bacteria that was living in canned food, the dose consumed was extremely high. 405 cases were reported to the CDC in America with about 40 death cases. But of course this was some time ago and it was not in Singapore.
Botox actually has many other uses in the medical field that isn't done for cosmetic and aesthetic purposes. Eg, Botox can be used to treat limb muscle spasticity associated with cerebral palsy. These cases need almost about 6.25 to 32 U/kg!
In fact a quick literature search and I found this list of different indications where Botox is useful.
Was this in fact a case of a patient needing medical treatment which required a large amount of Botox that resulted in a Botox Death?
Was this in fact NOT actually related to Botox but instead due to some other causes?
What may actually kill was it anaesthesia or a sedative agent injected into a vein?
We do not know for sure as details of the case has not yet been revealed. We shall have to await the pathologist results to come out to identify the true cause of death.

Secret RF - Depressed Acne Scars Treatment in Singapore
Secret RF is a Fractionated Microneedle Radiofrequency device that can be used for Acne Scar Treatment
This is the latest addition to The Clifford Clinc's armour of lasers and it is used to complement Clifford's Infini Fractional Microneedle Radiofrequency device for treatment of depressed acne scars.
Secret RF uses radiofrequency energy to stimulate collagen growth in the deep dermal layers of the skin. Similar to Infini in concept, the difference between the Secret RF machine and Infini is the ability to use non-insulated needles in Secret RF and semi-insulated needles in Infini. Also with the ability of RF assisted subscision from the Secret RF device, a larger variety of depressed acne scars can now be addressed in a single setting as compared to before.
Patients undergoing depressed acne scar treatment are often concerned with side effects, post treatment recovery time as well as efficacy. Fractionated microneedle radiofrequency devices (including Secret RF and Infini) have a much shorter down time profile due to minimal damage to the epidermal barrier. They also have a much better safety profile with a much lower post inflammatory hyperpigmentation incidence as compared to ablative lasers like fractional co2 lasers.
Why is the recovery for Secret RF and Infini faster? This
is largely due to the finely designed microneedles that do little damage to the
epidermis. Radiofrequency energy can induce electrical current which result in heating
of the dermal tissue hence improving the acne scars. Lasers on the other hand
generate heat by delivering energy to chromophores or pigments within the skin,
generating heat through a process called photothermolysis. This may somewhat
explain why lasers may have a higher incidence of hyperpigmentation if too high
powers are used in an attempt to get more results in acne scar treatment.
Infini vs Secret RF
So one might ask, why have 2 devices that seem to work the same way? The truth is as many with acne scars know is that acne scars is not an easy problem to treat. The concept of Semi-Insulated Needles have proof safe with acne scar remodelling, skin tightening as well as pore refining. Non-insulated Microneedle Fractional RF from the Infini was never a viable option but from Secret RF, this option has now become feasible due to the difference in tip profile both in terms of size, material and duration where the tip can be left into the skin.
Moreover, Secret RF now as a RF assisted subscision tip that cuts through anchoring scar fibers more effectively than the traditional subscision needle. With this new subscision technique, you would expect less bruising, less swelling and less down time for faster recovery with Secret RF for depressed acne scar treatment. Rolling scars that were traditionally treated with subscision or microneedle assisted subscison can now be more accurately targeted with the Secret RF machine.
