Men have a growing interest in cosmetic dermatologic treatments. Botulinum toxin type A (BTX-A) treatment offers a minimally invasive approach to improving facial lines and is often the first cosmetic procedure chosen by male patients. In general, men can be treated with the same techniques as women, but often require more units of BTX-A. Glabellar lines in the male have been the most well-studied with a recommended starting dose of 40 U. Some men may require up to 80 U in the glabellar complex. The most common cause of an inadequate result in male patients is under-dosing. Forehead lines require care, as many men with horizontal lines have low-positioned eyebrows, and excessive relaxation of the lower frontalis muscle can drop their brows further. Special consideration should be given to the male brow when treating men. Lateral orbital lines can be treated with a starting dose of 15 U per crow's foot. Men may need additional injections to the orbicularis oculi muscle as many men have a broad circumferential orbicularis. The lower face is amenable to BTX-A treatment in men. BTX-A can be used to reduce axillary sweating and improve armpit odor. BTX-A shows promise in treating benign prostatic hyperplasia, and may in the future become a first-line treatment.
男性对美容皮肤科治疗的兴趣日益浓厚。A型肉毒毒素（BTX-A）治疗为改善面部皱纹提供了一种微创方法，通常是男性患者选择的首个美容程序。一般来说，男性可以采用与女性相同的技术进行治疗，但通常需要更多单位的BTX-A。男性眉间纹的研究最为充分，推荐起始剂量为40单位。有些男性眉间区域可能需要高达80单位。男性患者治疗效果不佳的最常见原因是剂量不足。额纹的治疗需要谨慎，因为许多有水平纹的男性眉毛位置较低，额肌下部过度松弛会使眉毛进一步下垂。治疗男性时应特别考虑男性眉毛。外侧眶周纹起始剂量可为每处鱼尾纹15单位。由于许多男性眼轮匝肌较宽，可能需要对眼轮匝肌进行额外注射。男性的下面部适合进行BTX-A治疗。BTX-A可用于减少腋窝出汗并改善腋下气味。BTX-A在治疗良性前列腺增生方面显示出前景，未来可能成为一线治疗方法。
