The Botox timeline, week by week

Day 1	Small bumps at the injection points settle within hours. No lying down, rubbing or intense exercise for the rest of the day.
Day 2 to 5	First softening of the lines.
Day 10 to 14	Full effect. This is when injectors usually check the result and add a small top-up if needed.
Week 8 to 12	Movement gradually comes back.
Month 3 to 4	Most people book their next appointment.

What makes Botox wear off sooner (or last longer)

Dose: fewer units wear off faster. Writing down your units per area shows what works for you.
Area: forehead, frown lines (glabella) and crow's feet each behave differently.
Strong muscles and fast metabolism: very active muscles and lots of intense exercise are often linked with shorter results.
First treatment: first-timers often find it fades closer to 3 months; many regulars find it lasts a little longer.
Product: Botox, Dysport, Xeomin and other brands work in similar time frames, but the units are not interchangeable between brands.

When to book your next Botox appointment

Book when you notice movement coming back, rather than waiting until the effect is completely gone. For many people that is every 12 to 16 weeks. Many injectors recommend not having it more often than about every 12 weeks, so ask yours what interval suits you.

Tip: put the next appointment in your calendar on the day of your treatment, together with the units, product and areas. Next time you can tell your injector exactly what you had.
