What if botox for sweating does not relieve body odour?

Body odour is produced when substances on the skin are broken down, so reducing sweat does not remove every source of smell. Odour may come from areas that were not injected, damp clothing, skin folds, a local infection, or a change in products. The injection may also have been placed for sweating in one region while the odour is coming from another.

Timing matters: the treated area may need review before a conclusion is made about the response. Tell the clinician whether sweating changed, where the odour begins, whether there is itching or rash, and whether the smell is new or unusually strong.

Wash gently, dry skin folds carefully, change damp clothing, and use clean breathable garments. Avoid applying strong fragranced products to irritated skin. Arrange follow-up with the injector if odour persists, especially if sweating improved but the smell did not. They can examine the skin, review injection sites and technique, and consider whether another treatment or a separate diagnosis needs attention.

Seek prompt care for painful redness, warmth, swelling, pus, open skin, fever, or a rapidly changing odour from one area. Urgent assessment is needed for facial swelling, widespread hives, difficulty breathing, or other signs of a serious reaction after treatment.

Ask: Did sweating decrease where injections were given? Could the odour be coming from another area or an infection? When should the treatment be reviewed? Which cleansers or antiperspirants are suitable? Do I need testing for another cause?
