The question "how long does botox last" has a standard answer of 3–6 months — but the truth is more nuanced. Several factors affect the duration, and some areas last longer than others.
How long does botox last — average data
- First treatment: 3–4 months
- Second/third treatment: 4–5 months (the effect can be prolonged over time)
- Established treatment pattern: up to 6 months
What affects how long botox lasts?
1. Treated area
- Forehead / frown line: 3–4 months
- Crow's feet: 3–5 months
- Jawline (masseter): 5–7 months (larger muscle, higher dose)
- Lip flip: 6–10 weeks (short duration)
- Hyperhidrosis (sweating): 4–9 months
2. Dose
A higher dose gives a longer duration — but more units also cost more. If underdosed, the effect can wear off in under 2 months.
A fast metabolism (younger people, athletes) breaks down botox faster. Older and more sedentary people often get a longer-lasting effect.
4. Muscle strength
People with very strong facial muscles (lots of facial expressions, brow movement) often see a shorter duration.
5. Lifestyle
- Intense exercise → faster breakdown
- High sun exposure → negligibly faster breakdown
- Smoking → shorter effect
Why does botox last longer after a few treatments?
When the muscles do not actively contract, they gradually become weaker. After 2–3 treatments, the muscles do not have time to regain full strength between sessions — which is why the effect lasts longer.
When should you top up?
Usually every 3–6 months. Do not wait until the effect has completely worn off — topping up when about 70% of the effect remains gives more even results.
What happens when botox stops working?
The muscle gradually returns to full function — the wrinkles come back as before. Botox does not make wrinkles worse when it wears off.

Expert tips — how to make the result last longer
- Avoid intense heat for the first 2 weeks: saunas, hot yoga and sunbeds break down fillers faster.
- SPF 30+ sun protection daily — UV is one of the biggest enemies of both botox and fillers.
- No facial massage for the first 2 weeks.
- Products for the lips: Avoid overly intense exfoliation and retinol in the first week.
- Stop smoking or cut down — nicotine breaks down collagen and HA faster.
- Regular touch-ups: Top up before the effect has completely worn off — a 70% level is ideal. This gives more even results and often a longer duration over time.
- Hydration from the inside and quality skincare with hyaluronic acid support the filling effect.
