Does Botox for sweating help with body odour?

Fresh sweat is not usually strongly scented. Odour can develop when skin bacteria break down sweat and other substances, especially in warm, damp folds such as the underarms. Botulinum toxin injections reduce signals from nerves to sweat glands in the selected area. Less moisture may make that environment less favourable for odour, but the treatment does not act as a deodorant or antibacterial wash.

The result depends on why the odour is present, where sweating occurs, and whether the treated area is the main source. Odour can persist if it is linked to skin infection, clothing, hygiene products, diet, or another medical issue.

Tell the clinician whether odour appears with sweating, whether it affects one area or several, and whether you have rash, scaling, drainage, or itching. Gentle washing, thorough drying, breathable clothing, and regularly changing damp garments can reduce moisture. A clinician may suggest an antiperspirant, treatment for an identified skin condition, or botulinum toxin when excessive sweating is the main contributor.

Discuss the planned area, expected duration of benefit, possible temporary injection-site effects, and alternatives before treatment. Use only a qualified medical professional for injections.

Arrange an assessment for a sudden change in odour, a persistent unusual smell, painful or inflamed skin, sores, discharge, fever, or unexplained night sweating. Seek urgent advice if severe illness, breathing difficulty, confusion, or rapidly spreading redness accompanies the odour. These features need evaluation rather than cosmetic treatment alone.

Ask whether excess sweat is the likely contributor, whether the odour suggests infection, which areas would be treated, and what other options fit your symptoms. Ask how to care for the skin afterward and what changes should prompt a review.
