In addition to decreasing wrinkles, some users of Botox have suffered serious injuries, including muscle weakness to difficulty swallowing or breathing.  Botox cosmetic is approved for the removing of deep wrinkles between the eyebrows.  The FDA ruled that Botox cosmetic should carry a black box warning that underscores “the possibility of experiencing a potentially life-threatening distance spread of toxin….from the injection site after local injection.”  Symptoms from Botox injections can take days to occur, so it is important to be on the lookout after any Botox injection.
