When is Botox for sweating recommended for bromhidrosis?

Bromhidrosis is unpleasant body odour produced when sweat mixes with bacteria and other substances on the skin. The injection reduces signals from nerves to sweat glands in a treated area. Less moisture can make the skin less favourable to odour-producing bacteria, but the injection does not remove every possible cause of odour. A clinician should check for skin infection, retained moisture, clothing or hygiene factors, and medicines or health conditions that may increase sweating.

Arrange an assessment with a qualified dermatology or medical aesthetics clinician. Describe where the odour occurs, when sweating is strongest, whether one area is affected, and what antiperspirants or cleansing measures you have tried. Treatment is area-specific, so the clinician will discuss whether the underarms, hands, feet, or another site is suitable. Follow aftercare instructions and keep the area clean and dry as advised. Ask about temporary weakness, irritation, bruising, and the possibility that odour may persist if sweating is not the only contributor.

Seek medical review promptly if odour begins suddenly, sweating occurs mainly during sleep, or the skin is painful, swollen, cracked, draining, or feverish. These features can point to infection or a wider medical issue that needs evaluation rather than cosmetic treatment. Get urgent help for breathing difficulty, widespread hives, or severe weakness after any injection.

Ask whether excess sweating is clearly driving the odour, which area would be treated, what alternatives fit your skin, and how you should manage moisture and clothing afterward.
