Think about it this way: people make facial expressions every single day, whether it's expressing an emotion (i.e. smiling) or simply out of habit (i.e. raising your brows). Making facial expressions causes temporary dynamic lines to show up in your face. These lines go away when your face returns to rest. However, as you continue to make facial expressions, day after day and year after year, and as your skin ages, these lines start to get etched in your skin. That's when frown lines get progressively deeper for people who frown all the time. Or when crow's feet stay put even after you stop smiling or squinting. Eventually, what once were dynamic wrinkles become wrinkles that are just there, even when you don't make any facial expressions.
Botox takes three to five days to kick in, with the full effect becoming apparent within two weeks. Some people say they know when it’s taken effect because it suddenly feels like there’s duct tape on their forehead. “Botox will affect the way your facial muscles move, and it can feel funny when you can’t move your face to make a particular expression,” Dr. Shainhouse explains. “Also, sometimes injection of Botox in one area can affect another area—for example, injecting too low on the forehead to reduce wrinkles above the brows can actually end up lowering the brows, which is not always ideal. You may also experience a super-tight feeling in the beginning, before your body has time to adjust to the toxin.” These are the 50 things your surgeon won’t tell you.
BOTOX® treats the symptoms of severe underarm sweating when topical medicines do not work well enough in people 18 years and older. It is not known whether BOTOX® is safe or effective for severe sweating anywhere other than your armpits. BOTOX® treatments temporarily block the chemical signals from the nerves that stimulate the sweat glands, resulting in reduced sweating.
