## Common Questions About Botox

Common Questions About Botox

Dr. Saetawut Lertlukpreecha explains the most frequently asked questions — clearly and simply.

“Doctor, is there a big difference between 40 and 50 units?”

“If I get 60 units, will it last 6 months?”

“More units = stronger results, right?”

Let’s make it clear:

More units doesn’t always mean better results.

It depends on your facial structure, muscle strength, and treatment goals.

💉 What is 1 unit of Botox?

Botox (Botulinum Toxin Type A) is measured in units, which refer to the amount of toxin used to relax a muscle.

• 1 unit ≠ 1 injection point

• 1 unit ≠ a fixed volume of liquid (Botox comes as powder and is diluted before use)

🧭 How many units are typically used?

Area	Average Units
Glabella (frown lines)	10–20 units
Forehead	10–20 units
Crow’s feet	6–12 units
Bunny lines (nose wrinkles)	4–8 units
Jaw (slimming)	25–50 units per side
V-Shape Lift	8–12 units
Neck (Nefertiti Lift)	20–30 units

💡 What do 40 / 50 / 60 units actually do?

40 units:

• Great for softening forehead lines, frown lines, and crow’s feet

• May include a small V-lift

• Not enough for full jaw slimming

50 units:

• For deeper wrinkles or one-sided strong jaw muscles

• Can cover most facial areas with light lifting or minor jaw contouring

60 units:

• For full-face rejuvenation + jaw slimming

• Suitable for strong facial muscles (e.g. in men or those with mild resistance)

• Can cover lines, lifting, and both sides of the jaw (25 units per side)

🕒 How long does Botox last?

Factor	Typical Duration
Authentic brands (Allergan, Xeomin, Nabota)	4–6 months
Injection site	3–4 months for fine lines, 4–6 months for jaw
Dose used	Higher doses may last slightly longer
Aftercare habits	Heavy workouts or jaw clenching may shorten effect

✅ Yes — 6 months is possible if the dose is right and you care for your results.

❌ But not every area will last 6 months.

🚫 More ≠ Better

• Too much Botox can cause stiffness or unnatural expressions

• Too little might not work — and feel like a waste

• A skilled doctor adjusts the dose based on your muscle strength and needs

🧑‍⚕️ Doctor’s Advice:

“I always begin by observing your expressions.

Some people frown or squint often without realizing it —

which means they may need more units in certain areas than others.”

✅ In Summary:

• 40 / 50 / 60 units = different goals and areas, not just “stronger” results

• It’s not about how much — but where and why

• An experienced doctor will find the right balance: natural, effective, and safe

• Results can last up to 6 months, but that depends on many personal factors

💡 Your face deserves more than just “more units” —

it deserves careful planning with a doctor who understands your needs.
