When you step into the world of aesthetic medicine, the choices can sometimes feel overwhelming. A decade ago, there was really only one name in town. Today, the market is filled with high-quality options, leaving many of our patients at LIV Clinic asking the same question: “What is the real difference between Allergan Botox vs Nabota?”

Is the premium price of the American original worth it? Or does the Korean newcomer offer better value for the same result? As the premier destination for facial sculpting in Koh Samui, we believe in empowering you with facts so you can choose the treatment that fits your face—and your budget.

We verify every vial in front of you, ensuring that what you pay for is exactly what you get.

The Contenders: A Brief Overview

Before we dive into the technical details, let’s meet the two brands dominating the conversation in 2026.

Allergan (The American Gold Standard)

Produced by Allergan Aesthetics in the USA, this is the original “Botox” that started it all. With over 30 years of clinical studies and usage, it is the most researched Botulinum Toxin Type A in the world. It is renowned for its precision and high protein purity (99.5%), which minimizes the risk of the body developing resistance over time.

Nabota (The Korean Challenger)

Manufactured by Daewoong Pharmaceutical in South Korea, Nabota is often referred to as the “premium” Korean option. It distinguishes itself by being the first Korean toxin to receive approval from the US FDA (marketed as Jeuveau in the States). Using patented HI-PURE Technology, it boasts a purity of 98.7% and is famous for its rapid onset of action.

Key Differences: Purity, Speed, and Spread

While both brands utilize the same active ingredient to relax muscles and smooth wrinkles, the manufacturing process creates subtle differences in how they behave under the skin.

1. Onset of Action (Speed)

If you have a wedding or a photo shoot in just a few days, this factor is crucial.

• Nabota: Known for being “fast-acting.” Many patients report seeing initial results in as little as 2 to 3 days.

• Allergan: Typically takes a bit longer, with results appearing between 4 to 7 days, reaching peak effect at two weeks.

2. Diffusion (Spread)

“Spread” refers to how far the product moves from the injection site.

• Allergan: Has a very controlled, narrow spread. This makes it ideal for precise areas like crow’s feet or lifting the eyebrows, where you don’t want the product to affect nearby muscles.

• Nabota: Has a slightly wider focus but is still very stable. It is excellent for larger muscle groups like the forehead or the masseter muscles (for jaw reduction).

3. Longevity

How long will your smooth skin last?

• Allergan: Generally offers the longest duration, often lasting 4 to 6 months depending on metabolism.

• Nabota: Very competitive, typically lasting 3 to 5 months.

To help you visualize the differences, we have broken down the technical specifications.

Which One Should You Choose?

The “best” choice depends entirely on your specific needs and history with wrinkle relaxers.

Choose Allergan if:

• Budget is not an issue: You want the absolute most established brand with the longest track record.

• Precision is key: You are treating very small, specific areas where you need the toxin to stay exactly where it is placed.

• Long-term use: You have been getting injections for years and want to minimize the risk of antibody resistance (where the body stops responding to the treatment).

Choose Nabota if:

• You need results fast: You have an event this weekend and need to look refreshed immediately.

• You want value: You want a high-quality, US FDA-approved product without the premium price tag of the American brand.

• Natural feel: You prefer a softer look that still allows for some natural expression, avoiding the “frozen” appearance.

Addressing the “Natural Look” Concern

At LIV Clinic, our philosophy is “Live Your Life Young.” Regardless of the brand you choose, the result depends 90% on the doctor’s technique and 10% on the product. Dr. Narathai uses a specialized micro-injection technique that softens facial lines while preserving your natural character. We don’t want to change who you are; we want to help you look like the best version of yourself.

Frequently Asked Questions

Is Nabota safe? Yes, absolutely. Nabota is one of the few Asian brands that has passed the rigorous testing of the US FDA. It is used globally and has an excellent safety profile when administered by licensed professionals.

Can I switch brands if I used Allergan before? Yes, you can switch. However, we usually recommend waiting until the previous treatment has fully worn off (about 4-6 months) to accurately judge the results of the new brand.

Does one hurt more than the other? No. The pain level is determined by the needle size and the injector’s hand, not the brand of toxin. We use ultra-fine needles and ice/numbing cream to ensure the experience is virtually painless.

Will I build up resistance to Nabota? Resistance is rare for most casual users. However, because Allergan has a slightly higher purity and lower complexing protein load, it statistically has the lowest risk. If you get injections very frequently (every 3 months or less), we might suggest rotating brands or sticking to high-purity options.

Why is Allergan more expensive? You are paying for the “original” brand equity, the decades of clinical data, and the manufacturing complexity required to achieve its high purity and stability. Nabota offers a more affordable price point because of different manufacturing technologies and market positioning.
