Should I avoid particular foods before and after Botox? eg: cayenne pepper, cinnamon etc? If so, why?

You do not have to avoid any foods before or after Botox treatment, according to any studies. One thing to keep in mind is to minimize exposure to medicines that may increase bleeding or bruising prior to getting your Botox treatment (such as Aspirin, Ibuprofen, and even some vitamins may contain Ginseng).

With any healthy balanced diet you should be fine. Do avoid aspirin, Motrin or blood thinners,, Many herbal supplement's can have blood thinners (such as Ginko).   When in doubt about a product or food check in with your PS.Best wishes.

There are no foods that need to be avoided. It's necessary to notify your injector of any medicine, ie. blood thinners, that you may be taking. See an expert. Best, Dr. Emer
