How long does a Botox injection work?

A Botox injection works on average for 3 to 4 months, with effects sometimes lasting up to 6 months. Initial results become visible after 3–5 days, with the full effect appearing after about two weeks. Over time, muscle activity gradually returns, which is why repeat treatments are usually needed every 3–6 months.
