Where is the botulinum toxin injection administered to treat axillary osmidrosis?

Anti-odor injections are typically administered in the axillary (underarm) region; however, the exact injection sites may vary depending on the individual’s specific treatment plan and the type of medication used. Axillary odor (bromhidrosis) can be treated either with anti-odor injections or laser therapy. Details are as follows:

1. Anti-odor injections: These injections utilize ultra-fine, virtually scarless needles to deliver multiple localized injections that interfere with neurotransmitter transmission to the apocrine glands in the axilla, thereby effectively suppressing glandular secretion and eliminating odor. This method is also highly effective for treating refractory hyperhidrosis (excessive sweating). Due to its high efficacy, non-surgical nature, minimal discomfort, and rapid recovery, it is widely favored by patients.

2. Laser therapy for axillary odor: Laser treatment yields relatively ideal results for bromhidrosis. It works primarily on the principle of photothermal action—laser energy is directed onto the skin surface and penetrates into deeper layers, causing dehydration and coagulative necrosis of the apocrine glands, hair follicles, and associated tissues, thereby permanently impairing their secretory function and achieving therapeutic outcomes.

Both anti-odor injections and laser therapy cause minimal damage to the skin and leave no visible scarring post-treatment. However, patients should seek treatment only at reputable, licensed aesthetic medical institutions.
