Yesterday at 7:00 pm I got botox for the square jaw. There were four doctors, but the female teacher got it. They said that you shouldn't wash your face in the shower before the needle hole closes after getting the botox, so it's better to do it after three hours . It's more developed than this average. Even today, my mouth is tingling, but I think I can see the effect.. They say that the effect appears in the 4th to 8th week, but I 'll post again at that time.
