How does BOTOX® work?

Botox works by blocking nerve impulses to the injected muscles. This reduces muscle activity and relaxes facial lines. BOTOX® uses solutions of a purified protein derived from the Clostridium botulinum bacterium to reduce the activity of specific facial muscles responsible for some facial lines and wrinkles. When we make a facial expression, muscles react by contracting, tugging on the overlying skin and creating creases and folds. BOTOX® works by preventing nerve signals that cause these muscle contractions so lines and folds can’t form. As a result, the injections can temporarily smooth moderate to severe frown lines and facial wrinkles caused by movement.

What happens during treatment?

Treatment begins with a thorough assessment of the patient’s facial anatomy to locate the ideal injections sites. During treatment, BOTOX® is injected using very fine needles, and most patients report no discomfort beyond a tiny pinching sensation. Once treatment is complete, there may be some mild temporary bruising that can last for about a week to 10 days. Once treatment is complete, it’s important to avoid rubbing the area to prevent BOTOX® from spreading to adjacent tissues where it may cause temporary localized paralysis or weakening, especially around the eye lids.

How long will it take to see results following BOTOX® treatment?

Most patients see results within about two weeks of treatment, with continued improvement during the next few weeks. Results last about four to six months and can be “touched up” indefinitely. Many patients who have regular BOTOX® injections find their lines and wrinkles soften over time so they can extend the time between injections while still maintaining their results.

Is BOTOX® safe?

Yes, BOTOX® is approved by the FDA for the treatment of dynamic wrinkles and for many other medical treatments.

Preparing for Your Appointment

Products to avoid:

Substances that increase risk of bruising, such as blood-thinning drugs (Coumadin), Vitamin E, aspirin, Motrin, and other non-steroidal-anti-inflammatory drugs 7 days prior.


  • Pregnancy or breastfeeding
  • Neurological disease, such as myasthenia gravis

Botox is used for the successful treatment of facial wrinkles. There are also other brand names, such as Dysport and Xeomin. We use both Botox and Xeomin because of their safety and effectiveness.

Botox and Xeomin are most often used on forehead lines, the lines between the eyes, known as the glabellar region and crow’s feet (lines around the eyes). Wrinkles in other areas of the face are not usually amenable to this treatment and are more commonly treated with creams, lasers, or fillers.

How is Botox Administered?

Getting Botox or Xeomin takes only a few minutes and doesn’t require anesthesia. They are injected with a fine needle into specific muscles with only minor discomfort. It generally takes 7 to 14 days to take full effect, and it is best to avoid alcohol starting at least one week before the procedure. You should also stop taking aspirin and anti-inflammatory medications two weeks before treatment to reduce bruising.

The effects of Botox and Xeomin will typically last four to six months. As muscle action gradually returns, the lines and wrinkles begin to reappear, and additional treatments will be necessary if one wants to maintain the previous effect. The lines and wrinkles often appear less severe with repeated treatments because the muscles are being trained to relax.
