In a city where temperatures pass forty degrees, sweating seems ordinary. But there is a difference between normal sweat that cools the body and hyperhidrosis that embarrasses you in an air-conditioned meeting or has you changing clothes twice a day.
What is hyperhidrosis?
A condition in which the sweat glands produce more than the body needs to regulate temperature. It most often affects the underarms, palms and feet, sometimes the face and scalp, and usually begins in adolescence.
Signs that point to it
- Visible sweating without heat or exertion.
- Sweat marks on clothes that shape your choice of colours.
- Sweaty palms that get in the way of writing, handshakes or using your phone.
- Regular deodorants are not enough.
How does Botox treat it?
Botox temporarily blocks the nerve signal that activates the sweat glands in the treated area. This does not affect the body's ability to regulate temperature, because the treated areas are small relative to the whole skin surface.
- Session: about 20 to 30 minutes of fine, superficial injections.
- Results: begin within days and are complete at about two weeks.
- Duration: usually 4 to 6 months, longer for some people.
Many patients book before summer or ahead of a big occasion such as a wedding.
Tips that help alongside treatment
- Clinical antiperspirants (not just deodorants), applied at night to dry skin.
- Cotton or moisture-wicking fabrics.
- Less caffeine and spicy food if they trigger your sweating.
When to get checked first
If sweating starts suddenly later in life, affects the whole body, or comes with weight loss or night sweats, other medical causes — such as thyroid imbalance — should be ruled out.
