Botox is one of the most commonly used cosmetic treatments today. Among all the brands available, Allergan Botox is often seen as the most reliable choice. It is known for its safety, accuracy, and consistent results. Many dermatologists and aesthetic clinics trust it to soften fine lines and refresh the face without surgery.

If you are thinking about trying Botox for the first time or switching to a higher-quality brand, it helps to understand what Allergan Botox is and what you can expect from the treatment.

This guide explains everything in a simple way. You’ll learn what Allergan Botox does, how it works, how many units you may need, who the treatment is suitable for, and answers to common questions.

What Is Allergan Botox?

Allergan Botox is a purified form of botulinum toxin type A. It is made by Allergan, a well-known pharmaceutical company in the USA. It is FDA-approved and one of the most researched cosmetic injectables in the world.

Its main job is to relax specific facial muscles that create expression lines. These include forehead lines, frown lines, and crow’s feet.

Because of its purity and predictable results, many clinics in Thailand prefer using Allergan Botox for patients who want safe and natural-looking outcomes.

How Allergan Botox Works

Allergan Botox works by reducing communication between nerves and the facial muscles they control. This helps calm repetitive movements such as frowning, squinting, and raising the eyebrows.

Once injected, you can expect:

The targeted muscle to relax
The skin above it looks smoother
Fine lines to soften
A fresher and more relaxed expression

Only the treated area is affected. When performed by an experienced doctor, your face will still move naturally. The goal is to soften harsh expressions, not create a frozen look.

Popular Treatment Areas for Allergan Botox

Allergan Botox can be used on several areas of the face and neck. Common treatment areas include:

Forehead lines: Helps smooth horizontal lines while keeping brow movement natural.
Frown lines: Softens the vertical lines between the eyebrows.
Crow’s feet: Reduces the fine lines that appear around the eyes.
Bunny lines: Smooths the wrinkles that appear when scrunching the nose.
Brow lift: Gently lifts the brows to open up the eyes.
Chin dimpling: Helps improve uneven or bumpy skin texture on the chin.
Neck bands: Softens visible vertical neck lines.
Masseter reduction or facial slimming: Helps slim the jawline and reduce teeth grinding.
Gummy smile correction: Reduces the appearance of excess gum when smiling.

How Long Does Allergan Botox Last?

You may start noticing improvements within 3 to 7 days, with full results around the two-week mark.

Most people find that results last about 3 to 5 months. Longevity depends on:

Your natural metabolism
How expressive your facial muscles are
Treatment area
Lifestyle habits such as exercise intensity
Whether it is your first or repeated treatment

With regular treatments, results may last longer since the muscles gradually become less active.

How Many Units of Allergan Botox Are Needed?

The number of units depends on your anatomy, muscle strength, and desired result. Here are general estimates:

Treatment Area	Approx Units
Forehead lines	8 to 15
Frown lines	15 to 25
Crow’s feet	10 to 12 per side
Brow lift	2 to 4
Bunny lines	4 to 6
Chin dimpling	6 to 10
Gummy smile	2 to 4
Masseter slimming	25 to 40 per side
Neck bands	25 to 50

Your doctor will tailor the dosing to ensure the outcome looks natural.

Benefits of Choosing Allergan Botox

High Purity and Safety

As one of the most researched aesthetic products, Allergan Botox is known for its exceptional safety record.

Natural and Predictable Results

Its consistency allows practitioners to deliver smoother, more balanced outcomes.

Long-Lasting Effects

Compared to some alternatives, many patients report longer-lasting results with Allergan Botox.

Most people resume normal activities immediately after treatment.

Allergan vs. Dysport: Key Differences

Both Allergan and Dysport use botulinum toxin type A, but they behave differently.

Diffusion

Dysport spreads slightly more, better for larger areas. Allergan Botox offers a more controlled, precise application.

Unit Conversion

Units are not interchangeable. (Example: 3 units of Dysport ≠ , 3 units of Allergan Botox)

Onset Time

Dysport may show results faster (2–3 days). Allergan Botox usually begins working in 3–5 days.

Longevity

Many patients feel that Allergan Botox lasts slightly longer and offers more predictable results.

Your doctor may recommend one over the other depending on your goals and facial structure.

How to Prepare for an Allergan Botox Treatment

Botox treatment preparation is important to ensure a smooth procedure and long-lasting results.

Before treatment:

Avoid alcohol for 24 hours
Stop blood-thinning supplements for a few days
Avoid ibuprofen or aspirin unless prescribed
Arrive with a clean face
Stay hydrated

After treatment:

Stay upright for 3 to 4 hours
Do not touch or massage the area
Avoid heavy workouts for 24 hours
Avoid heat, saunas, and steam rooms for 24 hours

Following these steps helps you get the best results.

How to Check if Your Allergan Botox Is Authentic

Because counterfeit injectables do exist, choosing a reputable clinic is essential. Here’s how to verify authenticity:

Clear Allergan packaging with a hologram
Correct batch number and expiry date
“Botox Cosmetic” printed on the vial
Proof of USA origin
The clinic will show the vial if you request it
Pricing aligned with standard market rates

If a price seems unusually low, it is worth being cautious.

Bangkok has many aesthetic clinics, but it’s important to choose one that prioritizes safety, expertise, and authenticity. Look for a clinic that:

Employs certified doctors experienced with facial anatomy
