What Is Botox Treatment?

Botox is a popular injectable treatment that uses safe amounts of Botulinum toxin type A to reduce or eliminate facial lines and wrinkles.

Facial lines and wrinkles are common aging symptoms that form due to the repeated movement of muscles on the delicate skin. Facial movements like smiling, frowning, chewing, and squinting can also make these symptoms appear.

Botox treatment works by blocking signals from the patient’s nerves to their muscles. This prevents the treated muscles from contracting, resulting in minimum muscular symptoms.

While Botox is a temporary treatment, regular small doses can keep a patient’s skin healthier and younger for a long time.

Due to its ability to eliminate wrinkles, Botox injections are commonly used to treat:

  • Crow’s feet, or wrinkles that appear near the eyes
  • Frown lines between eyebrows
  • Forehead creases

It also treats underlying muscular conditions such as:

  • Amblyopia (lazy eye)
  • Chronic migraine
  • Excessive sweating
  • Eye twitching
  • Neck spasms
  • Overactive bladder

Side Effects of Botox Treatment

What side effects do patients treated with Botox expect to see?

Generally, Botox is considered a safe treatment with very rare cases of adverse side effects.

Between 1989 and 2003, the Food and Drug Administration (FDA) reported only 36 cases of adverse side effects associated with Botox treatment. However, out of the 36 cases, 13 were related to other underlying medical conditions.

Like many other cosmetic treatments, Botox may elicit some mild, temporary side effects on the patient.

Some of its common side effects include:

  • Swelling and tenderness around the injected area
  • Pain and mild bruising around the injected area
  • Reddening of the skin
  • Drooping eyelids

Other side effects of Botox that patients have reported include:

  • Headache
  • Fever
  • Nausea
  • Dry eyes
  • Excessive tearing
  • Crooked smile or drooling

Most of these side effects are usually mild and subside within a few days.

According to the American Society of Plastic Surgeons, it’s unlikely that Botox injection side effects will spread beyond the injection area and cause severe effects on other parts of the body.

Patients can lower their risk of experiencing side effects by ensuring their dermatologist or plastic surgeon is board-certified to administer Botox injections.

They’re less likely to experience adverse side effects if their Botox injections are prepared according to FDA standards and administered by experienced healthcare professionals.

What to Expect During Recovery

With Botox injections, there’s no downtime for healing. Once patients receive the injections, they’re free to immediately resume daily life activities.

The outcome of Botox injection is usually seen within a week when the patient’s skin becomes smooth, flawless, and free of wrinkles.

However, the impending side effects may take a few more days for the swelling, bruises, and redness to disappear completely. After complete healing, the patient starts seeing reduced wrinkles and smoother skin.

The effects of Botox treatment can last between three to four months.

Frequently Asked Questions About Side Effects

Here are some common questions about Botox treatments:

1. How Long Do the Side Effects of Botox Last?

Generally, the side effects of Botox last a few days to weeks. However, the duration varies from one patient to another. The side effects also vary depending on the condition for which the patient was treated. If you experience side effects that last longer than a few weeks or become severe, seek professional advice from your surgeon.

2. Will I Experience Side Effects If I Discontinue Botox Treatment?

Patients don’t experience side effects when they stop Botox treatment. However, when its action subsides, the patient’s muscles and skin often retrieve back to their original appearance. This means that their previous skin condition may reappear. Patients should talk to their surgeons about how stopping the treatment can affect their previous condition to take the necessary precautions.

3. Is There Recovery Time from Botox Treatment?

With Botox treatment, there’s no downtime for recovery. Patients can resume normal activities immediately after injection.

However, they need to refrain from intensive physical activities during the first couple of days.

4. Will Botox “Freeze” My Face?

Botox will not freeze your face. The belief that Botox injection causes a frozen (immobile) look on patients’ faces is a misconception. While facial stiffness may occur in some first-time patients (or those who need larger doses of Botox), the stiffness often fades away quickly.


Botox injections are definitely a good choice for people who want smoother, flawless skin with minimum wrinkles and lines. Like most medical procedures, patients considering the injections should expect some mild side effects. However, to reduce the risk of complications, they should go to experienced and board-certified healthcare professionals who understand fully how the treatment works.

Dysport is also an alternative treatment for Botox, which achieves the same effects of smoothening fine lines and restoring a relaxed appearance. Patients should also always consult their surgeons about the procedure, side effects, and expected outcome before taking the injection. This will help them stay safe even as they look to improve their facial appearance through Botox or Dysport injections.
