We tell patients that the Botox procedure needs to be repeated every three to four months. Although we tell patients it will last for four to five months, sometimes six months, that really depends.
When you do get a side effect like an asymmetrical smile, it can be adjusted by adding a little bit more Botox to balance out the antagonistic muscles. The effect of Botox on the unevenness usually wears out in about four to six weeks anyway. It doesn't really last three to four months. So that's where, you know, tell patients that it will soften and it will become less obvious in about four to six weeks.
