A review published in Dermatologic Therapy  reports that men can be treated with botulinum toxin Type A in the same way as women, but they may require higher doses in all treatment areas.

There has recently become a growing interest in aesthetic procedures by men. Although most practices see a majority of women, the number of male patients who seek treatments is slowly increasing.

According to the review, men often require more units of botulinum toxin Type A compared to women because men have a greater muscle mass. Similarly, it has been a common clinical observation that larger, stronger men need more units per treatment area than slender, small-boned men. The most common cause of inadequate results in male patients is under-dosing, which may lead to men requiring additional injections.
