how long does it take for botox to work

Botox typically starts to work within 1 to 3 days after the injection, with most people beginning to see noticeable improvement around 3 to 5 days. The full or maximum results usually appear about one to two weeks (7 to 14 days) after treatment. This timeline can vary based on individual factors such as age, muscle mass, skin elasticity, gender, the volume and type of Botox used, and the area treated. Some people may see effects as early as 24 to 48 hours, especially for shallow wrinkles like forehead or frown lines, while others may take up to two weeks for the full effect. The Botox effects typically last for 3 to 4 months before muscle activity gradually returns to normal.
