Common questions concerning wrinkle relaxing injections

Provided below are some of the common questions asked by patients, and answers regarding this treatment. These questions and answers about botulinum toxin are to provide information and in no way intended to replace a consultation.

Botox® is the brand name for the original and most popular botulinum toxin treatment. Botox is an FDA-approved treatment for the temporary relaxation of overactive muscles. A spin-off of its original use in spasticity was that it smoothed out frown lines.

Botulinum toxin treatment causes temporary blocking of nerve signals to muscles. So those expression lines that occur when we use our facial muscles will look softer once the treatment has reached full effect.

In the upper face, vertical frown “eleven” lines between eyebrows, “crow’s feet” lines at the corners of the eyes which are distressing to patients, are approved indications for treatment with botulinum.
Botulinum is also used to improve lower face expression lines, such as a downturned “mouth frown” and prominent neck lines.

Botox® injections are given using very fine tiny needles, usually no numbing is required. However when a large number of injections are required, such as for treatment of excessive sweating with botulinum toxin, numbing cream is applied prior to treatment.

Side effects of treatment with botulinum toxin such as Botox ®, Azzalure (Dysport) include:

  • needle site redness
  • bruising or hematoma
  • if injected above the outer half of eyebrows, can cause the eyebrows to be heavy.
  • if injected too close to the upper eyelid or rubbed inadvertently causing migrate into the eyelid muscle, it can cause a droopy eyelid.

There are reports of side effects caused by distant migration of botulinum toxin, including weakness of swallowing. However, the current understanding is that when the total amount of toxin used is kept to the minimum required for effect, used after prudent medical consultation and understanding of the depth of injection and muscles being treated, Botox is a safe treatment in the right hands.

In the unfortunate event that you develop a droopy eyelid after treatment with Botox, you must contact your treatment provider immediately. At Reverse Time, this will be the physician who treated you. They will look into possible causes of this that could have occurred during treatment. However, it is often due to migration of the Botox into the eyelid elevation muscle because of rubbing, pressure from helmets and goggles or other lapses in aftercare. You will then be reviewed and your eyelid response to Iopidine (apraclonidine) eyedrops will be assessed. This is a test for whether a small eyelid lifting muscle has been affected by Botox.

If Iopidine relieves the droopy eyelid for a span of 2-3 hours, then you could use this following your physician’s advise until the effect of Botox wears off or weakens.

It is important to remember that all side effects of the Botox itself are temporary, and will be reversed over the duration of effect of the toxin, that is 10-12 weeks.

Unfortunately, there is a risk of getting a heavy eyebrow when the horizontal forehead wrinkles are treated overzealously with Botox. To understand why this happens, we must understand how the vertical and horizontal forehead lines are formed, when they occur with expression.

Vertical “11” lines are caused by the depressor muscles (which pull the eyebrows down and inwards) and the horizontal lines when you raise your eyebrows are caused by the frontalis muscle which acts to pull the eyebrows up and outwards.

It follows that for a good balanced result with Botox treatment, one has to accept a trade-off between the depressors and elevator action. Trying to “freeze” all the horizontal lines in the forehead with Botox will inevitably cause inability to raise the brows. Often this will be noted by patients as being unable to apply their eye makeup or mascara without manually lifting their eyebrows using a finger.

During consultation for Botox treatment, experienced injectors will ask you details of how your previous treatments with Botox or other botulinum toxin such as Azzalure went, did you have any side effects, heavy brows, droopy lids. This is important to understand how you respond and tailor a good Botox treatment for you.

The first 2 weeks are crucial to botulinum toxin treatment producing a satisfactory outcome.
Immediately after treatment, the needle marks may be visible. These will fade over the next day. There is no downtime.
Visible results become noticed in 10-14 days after Botox treatment.

The original question was “Will getting Botox on the outer corner of the eye that wrinkles when smiling, change the look of your expression when smiling?”

This question is not only about Botox treatment, but about the science and philosophy of expression and emotion.

On the surface it may seem the right thing to do to remove those smile lines that pop up at the corners of our eyes when we smile, especially since drug companies decided to call them by the ugly term “crow’s feet” – I call them smilies.
But is it really the right thing in terms of facial expression as a whole?
Probably not. A term in popular psychology is the “Pan Am Smile” named after the friendly but forced smile that was trained into the Pan Am flight crews when greeting people as part of their “great customer service” image.
Today, some may refer to it as the courtesy smile which is polite but superficial.
French physician Guillaume Duchenne (1806-1875) researched the smile in great detail in 1862.
His findings revealed that an artificial smile used only the large muscles on each side of the face, the zygomatic major, while a genuine smile, induced by a joke, involved the muscles running through the eyes, obicularis oculi, as well. The resulting effect is a visible wrinkling around the corners of the eyes that lies outside voluntary control. You really can’t help a happy smile smile – it just bursts upon your face!
Remember, these lines appear with smiling, but don’t leave creases unless your skin is deteriorating due to pile-up of dead cells or photo-aging (sun-damage).

In research circles, a genuine smile is still known as a ‘Duchenne Smile’ while a fake smile is a ‘Pan Am Smile’ after the air hostesses in the defunct airline’s adverts.
Duchenne described this “courtesy smile”, as “the smile that plays upon just the lips when our soul is sad.”
Science has actually proven this to be true – In the late 1950s, 141 female students at Mills College in California agreed to a long-term psychological study. Over the next 50 years they provided reports on their health, marriage, family life, careers and happiness. In 2001 two psychologists at Berkeley examined their college yearbook photos and noticed a rough 50/50 split between those showing a Duchenne or Pan Am smile. On revisiting the data it was found that those with a Duchenne smile were significantly more likely to have married and stayed married, and to have been both happier and healthier throughout their lives.
We now know the “Pan am smile” as the “Botox smile” because the rest of the face smiles but nothing happens around the eyes.
