Botox (Botulinum Toxin)
Botox reduces forehead lines, crow’s feet, and frown lines between the brows, slims the jaw, and lifts the brows. Results begin in 3–7 days and last 4–6 months at Sanambinnam Clinic (คลินิกสนามบินน้ำ), Nonthaburi.
In brief: what is Botox?
Botox (Botulinum Toxin Type A) is a substance that reduces muscle contraction in targeted areas when injected, so expression wrinkles (forehead, crow’s feet, between the brows) look smoother. It is also used to slim the jaw, lift the brows, and reduce sweating. Results begin within 3–7 days of injection and last about 4–6 months. It is a procedure that has been used in medicine for over 20 years.

Jaw Botox / masseter Botox: which kind of wide jaw is it for?
If you are concerned about a wide jaw or a face frame that does not look slim, jaw Botox aims to reduce the masseter (chewing) muscle that makes the lower face look wide. If the jaw prominence comes from bone or fat, the treatment is different, so the physician must assess the actual cause first.
See details of the jaw Botox service (jaw-slimming Botox): who it suits, when results appear, and what to know →Who Botox is suitable for
- People with horizontal wrinkles, such as forehead lines, frown lines between the brows, and crow’s feet
- People who want to slim the jaw contour
- People who want a brow lift without surgery
- People with localised excessive sweating (e.g. armpits, palms)
- People who want to prevent wrinkles increasing from facial expressions
Consult a physician first / not suitable for
- People who are pregnant or breastfeeding
- People with a muscle weakness disease (Myasthenia Gravis) or Eaton-Lambert syndrome
- People who are allergic to Botox components
- People with an infection at the injection area
- People taking Aminoglycoside medications should inform the physician
- People with a prior facial injury or facial surgery should inform the physician
What the physician assesses
- 1 Health history, current medications, and allergy history
- 2 Facial expressions and the muscles that work on the face, to identify the points best suited to injection
- 3 Wrinkle positions and depth, to determine the appropriate amount
- 4 Jaw structure (for jaw contouring)
- 5 The patient’s expectations, to explain the scope of results
Who Botox at Sanambinnam Clinic in Nonthaburi is for
People living around Sanambinnam, Ngamwongwan, Khae Rai, Bang Khen, or Mueang Nonthaburi who are researching Botox can come in for a physician assessment before deciding. The physician will look at where the muscles actually work, the health history, and each person’s expectations.
Botox planning should choose points and amounts that suit the face — not the same formula for everyone — to reduce the chance of a stiff or asymmetric look.
How the procedure is performed
Assessment and planning
The physician assesses the face, asking you to make various facial expressions, to identify the muscles and the points to inject.
Cleansing and marking the points
The facial skin is cleansed and the points to be injected are marked.
Botox injection
Botox is injected into the targeted muscles with a fine needle; it takes about 10–15 minutes.
Assessment and aftercare advice
The physician assesses the initial result and gives aftercare instructions.
Timeline and expected results
| Timeframe | Expected results |
|---|---|
| First 3–7 days | Wrinkles start to reduce slightly |
| 2 weeks | Full effect; wrinkles look clearly smoother |
| 4–6 months | The effect gradually returns to normal |
| Procedure time | About 15–30 minutes |
What are the risks and side effects?
Common (temporary)
- Slight pain/discomfort during injection
- Minor bruising
- Mild headache
- Slight swelling at the injection site
Less common
- Stiff face or unnatural expressions (if injected at the wrong points or in large amounts)
- Temporary droopy brow (PTOSIS)
- Temporary blurred vision
How the different Botox brands differ
Substances sold under the name “Botox” come in several brands, but all are Botulinum Toxin Type A products that differ slightly in spread, duration, and unit measurement. Most importantly, the units of each brand are not equal — for example, Dysport counts more units per vial than Botox because each Botox unit is stronger. As a rule of thumb, one unit of Dysport corresponds to roughly 2.5–3 units of Botox. Unit conversion must therefore be done by the physician who injects both brands; it should not be calculated from advertisements or non-physician staff.
| Brand | Characteristics discussed in clinical practice | Important note |
|---|---|---|
| Botox (Allergan) | The most studied for wrinkle reduction, with long-standing data | The industry’s reference unit; the most expensive in the group |
| Dysport (abobotulinumtoxinA) | Spreads more widely and needs fewer injection points; popular for jaw work | More units per vial; never convert units directly against Botox |
| Xeomin (incobotulinumtoxinA) | Small molecule with no complexing proteins; seen as reducing allergy from accessory proteins | This product’s units differ from other brands; use it according to the manufacturer’s guidance |
| Nabota (prabotulinumtoxinA) | Made in South Korea; registered and used in Thailand; cheaper than the imported group | Check the registration number with the Thai FDA and verify the lot number before every injection |
At Sanambinnam Clinic, the physician chooses the brand and the amount based on each individual assessment — not on price — and tells you the brand and lot number before every injection.
Botox compared with other options
| Option | Principle | Duration of effect | Suitable for |

Frequently asked questions
What is Botox?
Botox (Botulinum Toxin Type A) is a substance that reduces muscle contraction in targeted areas, making wrinkles caused by facial expressions look smoother. It has been approved by the Thai FDA for medical and aesthetic use for more than 20 years.
When do Botox results appear?
Results usually start to appear about 3–7 days after treatment and reach their full effect at 2 weeks. After that, the effect gradually returns to normal as the muscles start working again.
What can Botox be used for?
Botox is used to reduce horizontal wrinkles (forehead lines, frown lines between the brows, crow’s feet), slim the jaw, lift the brows, address excessive sweating (Hyperhidrosis), and contour the face.
How is Botox different from filler?
Botox reduces muscle activity, making movement-related wrinkles look smoother, while filler restores volume in areas that have hollowed or have deep lines. The two are often combined for better results.
Will my face look stiff after Botox?
When injected by a knowledgeable physician in the appropriate amount, the face will not look stiff — facial expressions still work normally, and the wrinkles simply look smoother. Over-injection or injection at the wrong points can cause unnatural expressions.
A note from Dr. Net
“Botox is one of the most studied products in aesthetic medicine. What matters is injecting at the right points and in the right amount. I ask patients to make various facial expressions to see which muscles work hard enough to create wrinkles, and only then plan the injection for a natural-looking result.”
