How long does BOTOX® Cosmetic last, and how often will I need a BOTOX® Cosmetic treatment?
A well-placed Botox treatment, administered by an expert injector, can last from three to six months, depending on the patient. Even after this time period, the muscles may remain relaxed for an additional time period, leaving a residual improvement in the frowning and wrinkles of the forehead. Botox injections can be safely repeated every three months but the frequency will depend on the needs of the patient. Still Dr. Hernandez does not recommend Botox to be administered in the same area more than twice per year.
