Understanding Botox Dosage: Why “Less” Isn’t Always More

When it comes to Botox, one of the most common misconceptions we hear is:“I just want a little bit — will it still last the same amount of time?”

While a lighter touch can be a great choice for first-time or preventative treatments, the truth is: dosage matters — not just for how you look, but also for how long your results last.

What Does Botox Actually Do?

Botox works by temporarily relaxing targeted muscles, softening the appearance of lines and preventing deeper wrinkles from forming. But for it to be effective, it needs to be dosed accurately based on your muscle strength, facial anatomy, and treatment goals.

Think of Botox like prescription glasses: the right lens strength is unique to your eyes — and the right dose is unique to your face.

Botox Dosage: What’s Considered “Standard”?

Each facial area has clinically studied dosage guidelines for safe, predictable results. For example:

Frown lines (glabella): ~20 units
Forehead lines: ~10–20 units
Crow’s feet (sides of eyes): ~12–24 units total
Masseter (jawline slimming): ~20–40 units per side
Neck bands (platysma): ~20–50 units, depending on severity

A person in black gloves uses a white pencil on a woman's eyebrow. The background is blurred with gray tones, creating a focused and professional mood.

Of course, these are starting points. At MediAesthetics our skilled injectors will customize the dose based on your muscle strength, movement patterns, and desired level of correction.

What Happens When You Underdose?

It’s understandable to want to start slow, especially if you’re new to injectables. But going too low — just for the sake of “less” — can lead to:

Minimal or short-lived results
Asymmetry or uneven relaxation
Muscle resistance building up over time
Needing more frequent touch-ups (which can cost more in the long run)

Underdosing doesn’t mean better. It often means underperformance.

If you're investing in Botox, it's important to dose effectively — not just minimally.

What Affects How Long Botox Lasts?

Even with proper Botox dosage, several factors can influence how long your Botox results last:

Muscle strength – Stronger muscles may need more product and may wear off quicker.
Metabolism – A faster metabolism breaks down Botox faster.
Consistency – Staying on schedule helps “train” muscles to stay relaxed longer.
Lifestyle – High-intensity exercise, chronic stress, sun exposure, and certain supplements can shorten the lifespan of your results.

Most patients enjoy smooth, refreshed skin for 3 to 4 months, with regular maintenance appointments keeping lines soft and subtle.

The Bottom Line: Trust the Process — and the Botox Dosage

Botox is a medical treatment, and achieving natural, long-lasting results is both a science and an art. The best outcomes come from precision, customization, and proper dosing — not just using less.

Our goal is never to "freeze" your expression, but to enhance your natural look with balance, harmony, and the right dose for you.
