How Long Does Botox Take to Work?

Great question. It's a common one. Typically most patient notice that their muscles begin to paralyze or weaken by 2-3 days after the injection of botox, but the full effect takes about 2 weeks to be reached. Some people reach it a bit faster than others. However, if your definition of working is that your wrinkles are gone, that can vary depending on the type of wrinkle.
For example, there are static wrinkles and dynamic wrinkles. Static wrinkles are wrinkles that are visible at rest and do not require your activation of your facial muscles to be seen. These wrinkles have typically been around longer and take longer to resolve, and may not resolve fully, but will typically at least soften significantly. Dynamic wrinkles are folds that are seen only with facial movement. These are typically addressed with one sesssion of botox, because all that is needed is to paralyze the muscles so that they can't form. Hope that makes sense. There are other treatments that can be used to help wrinkles, but a photo evaluation and ideally an in person evaluation is necessary for proper recommendations.

Typically with Botox, you will begin to see results after 3-5 days, with the full effects setting in at 2 weeks, although this varies from patient to patient. If you still experience lines in the areas that have been injected, you may need to discuss other treatment options, such as hyaluronic-acid based fillers or lasers.  

Hello, Botox works mostly with wrinkles that occur when you make facial expressions, which is why you are seeing the disappearance of the frown wrinkles but not the ones that show when you do not make an expression. For those, a combination of botox and fillers would probably be required to help see the results you are looking for.
