Washington, Dec 29 (ANI): A new study has revealed that men, who are treated with Botox for cosmetic procedures need higher doses of Botox in all treatment areas, as compared to women.

Though cosmetic treatments are largely restricted to women, the number of male patients seeking the procedure is slowly increasing.

The current study found that men often require more units of Botox than women.

Researchers theorize that this may be because men have a greater muscle mass than women.

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 Botox injections, the researchers said.

Various areas of the male face can be treated with Botox and injections need to keep in mind the greater muscle mass in men, the authors note.

The study is published in the November 2007 issue of the journal Dermatologic Therapy. (ANI)
