How long before Botox Works

BOTOX®, a prescription medication more generally known by the generic name “Botox,” is a common cosmetic treatment that safely utilizes a neurotoxin produced by Clostridium botulinum bacteria. 

Botox is indicated for treatment of a variety of musculoskeletal conditions, such as bruxism and TMJ, as well as for the treatment of crow’s feet and brow and forehead lines. It’s also regarded as an effective treatment for migraine headaches.

Botox is injected locally at the treatment site. It works by dulling nerve signals that would normally compel nearby muscles to contract, effectively freezing the muscle in place. This process does not happen immediately, however. That begs what’s perhaps the most pressing question for would-be patients interested in trying Botox: how long before Botox takes effect?

How long before Botox takes effect? 

Botox takes effect gradually over a period of days to weeks following the injection procedure. Patients undergoing treatment for facial lining, such as crow’s feet and forehead lines, typically notice a reduction of these lines over time. Patients undergoing treatment for other conditions, such as TMJ or migraine, may notice a lessening of symptoms in the days following treatment.

Depending on the condition being treated, dosing, and other factors, incremental results may take as little as three days after injection. Fuller Botox results typically appear after 10 to 14 days.

What variables may impact Botox results?

Several factors may affect how long a single Botox treatment takes to produce visible or tangible results:

 

  • The injection site and condition being treated. With equal dosing, Botox injections tend to produce results more quickly in smaller muscle groups. In cosmetic procedures specifically, Botox usually produces visible results more quickly where facial lining is finer, such as the corners of the eyes (crow’s feet). Botox typically takes longer to produce visible results and may require higher dosing or injection frequency in larger muscle groups where lining is severe, such as the forehead.
  • The dose and injection frequency. Botox dosing and injection frequency vary based on the condition being treated, its severity, and the muscle groups involved. All else being equal, higher dosing and more frequent injections tend to result in faster action. However, higher dosing may inhibit movement in the treated muscle groups, resulting in a less natural appearance.
  • The development of antibodies. Over time, the body may develop antibodies to Botox, according to at least five documented case reports. This can lessen the effectiveness of the treatment, compelling a higher effective dose in future treatments. 

 

How long do the cosmetic benefits of Botox treatment last?

The results of a single Botox treatment are durable but not permanent. Lighter doses of Botox typically start to wear off in two to three months, while heavier doses can last for four to six months. Also, a patient’s first treatment may not last as long as follow-up treatments. Because dosing can directly affect appearance, patients should discuss expectations with their providers before beginning treatment.

What can patients expect from a Botox treatment procedure?

Botox treatment is a non-invasive outpatient procedure that generally takes no more than 30 minutes to complete. The procedure itself involves a predetermined number of injections to the treatment site using a small-gauge needle. 

Though Botox injections aren’t usually painful, injection site soreness, numbness, or tingling can occur in the days following treatment. Other side effects may include headache, temporary facial or eyelid drooping, muscle weakness, and redness at the injection site. In most cases, these side effects are mild and dissipate within the first week to 10 days of treatment. 

The takeaway

When properly administered by a credentialed professional, Botox is considered a safe, effective treatment for a variety of conditions including, but not limited to, facial lining, bruxism, TMJ and migraines. Like all cosmetic and medical procedures, however, Botox treatment does present certain risks and results can vary. This is why patients and practitioners should thoroughly discuss potential complications, likely results, expected timelines and other factors about the procedure and its outcomes in advance of treatment.
