How Long Will the Results Last After a Botox Injection?

Introduction

How long Botox lasts is a common question—and the answer isn’t one size fits all. At Bayswater Dental Clinic, we help you understand what influences the duration of your results so you can plan follow-up treatments with confidence.

Typical Duration of Effect

In general, the aesthetic benefits of Botox (such as softened lines and reduced visible muscle activity) tend to last between 3 and 4 months. Some individuals may experience effects lasting a bit shorter or longer—ranging up to 5 or 6 months in favourable cases.

When You’ll See the Full Result

Early signs often begin around 3 to 5 days post-injection as muscles begin to relax.
Maximum smoothing and effect are generally noticeable by 10 to 14 days after treatment.
After that, the results gradually fade as muscle activity returns.

What Affects How Long It Lasts

Several personal and technical factors influence the longevity of Botox:

Factor	Influence on Duration
Muscle strength and activity	Heavier or more active muscles metabolize Botox faster, shortening effect
Dosage and coverage	Higher, well-targeted doses may yield longer-lasting results
Location treated	Some regions (e.g. forehead) may wear off faster than others
Metabolism & physiology	Faster metabolic rates often lead to earlier fading
Injection technique & precision	Skillful placement reduces “leakage” and preserves effect
Prior treatments	Repeated treatments sometimes extend duration over time

When to Schedule a Touch-Up

To maintain smooth results, many patients opt for retreatment every 3 to 4 months—before the effects fully disappear. Some patients wait until they see the first signs of wrinkle return before booking their next session. Over time, spacing may shift based on how your muscles respond.

Variations You May Experience

First-time users often find results wear off a bit sooner compared to subsequent sessions.
Certain brands or formulations may offer slightly longer duration in some muscles.
Lifestyle factors—sun exposure, smoking, vigorous facial movement—can shorten the effective period.

Summary

Botox results generally last three to four months, with full effect visible by two weeks and gradual fading thereafter. In some cases, effects may stretch toward five or six months depending on individual factors.
