Most men believe that bigger is better…and when it comes to Botox®, a bigger dose is indeed better for men.
Dr. Alastair Carruthers, a Botox® pioneer, presented a study during the 61st Annual American Academy of Dermatology meeting that proved men needed higher doses of Botox® Cosmetic to achieve the same results as women. Not only that, the level of smoothness of a man’s skin does not plateau with a certain dosage like it does in with women. In fact, the more Botox® a man gets, the better the results and the longer it lasts.
Dr. Carruthers injected 80 men and 80 women at seven different locations along the forehead. The women, who were separated into four groups of 20, were injected with 10, 20, 30 or 40 units of Botox®; the men received 20, 30, 60 or 80 units. While there was a great difference between the women who received 10 units and the women who received 20 units, the larger does did not extend the duration of the results.
The men, however, saw better and longer lasting results with each increasing dose. After six months, 40% of the men who were injected with 80 units and 25% of the men who received 60 units of Botox® still had visibly smooth brows.
The study also found that men could handle a higher dose of Botox® without any adverse effects. This study helps doctors to determine the accurate dosage of Botox® when treating male patients.
