How long it will last and other information:

Although the longevity of the treatment can vary. We will experience dry armpits for around 4 to 14 months.

How it works:

Botox works by blocking the secretion of acetylcholine; a neurotransmitter responsible for activating the sweat glands. Although sweating is the body’s natural mechanism of cooling down, in people with hyperhidrosis, the sweat glands are overactive causing excessive sweating. When the Botox is injected into the armpits The nerves are essentially paralyzed causing less sweat in that particular area of injection.


Target areas:

We may be considered as a good candidate for Botox if our sweating fails to improve with prescription antiperspirants. Botox has been FDA-approved for underarm sweating, but it can also be used to treat sweat from other areas such as feet, hands, head and face. Botox is used to treat sweaty palms and has a success rate of 80-90%, and a success rate of 95% in the treatment of sweaty forehead, which may last for 5 months.

This treatment requires a full bottle of Botox. Your practitioner will start by drawing a diamond shape and then inject the Botox just below the surface of the skin using fine needles. We may feel a slight prick when the needles hit the skin surface, but it’s only mild discomfort. We’ll receive several injections in a grid pattern approximately every 1 to 2 centimeters apart around the targeted area. The more units of Botox injected, the longer the drying effects lasts. The entire procedure can take 10 to 30 minutes to complete.


Immediately after the treatment, there is potential bruising or feeling of tenderness. But we can resume our normal activities as soon as we’re done with our Botox injections. After the injections, exercise, alcohol and stress can accelerate the body’s metabolism causing the Botox to break down faster. Therefore, it is advised to refrain from intensive exercise, consumption of alcohol and use of sauna for a few days. About two weeks after the treatment. Once the full effects of botox are visible, we should see our practitioner for a follow-up appointment. Where the practitioner will inject the botox into any spots that have been previously missed to ensure we get the treatment’s full benefit.
