how long does it take botox to work

Botox typically starts to work within 1 to 3 days after treatment, with most people noticing initial improvement around 2 to 4 days. Maximum results are usually seen about one week after the injection, and full effects can take up to 10 to 14 days to appear. The duration and onset can vary depending on individual factors such as age, muscle mass, gender, skin elasticity, type and volume of Botox used, and the area treated. Results generally last around 3 to 4 months before muscle activity gradually returns to normal.
