Botox is one of the most widely known treatments in aesthetic medicine, but it is also one of the most misunderstood. Some people think of it only as a wrinkle treatment, while others are surprised to learn it is also used for medical conditions such as excessive sweating. If you are considering Botox injections, this guide explains how they work, what they are used for, what to expect in the weeks after treatment, and how to choose a clinic.
Botox is a prescription-only medicine. It should only be given after an assessment by a licensed doctor, who can confirm whether it is suitable for you.
What Botox is and how it works
“Botox” is the brand name of one type of botulinum toxin type A, a purified protein used in very small, carefully measured doses. Other brands of botulinum toxin are also available, and they are not interchangeable dose for dose, which is one reason the person injecting needs proper training.
Botulinum toxin works by temporarily blocking the signal between a nerve and a muscle. When the muscle receives less signal, it relaxes. In aesthetic treatment, this softens lines caused by repeated muscle movement, such as frowning or raising the eyebrows. In medical treatment, the same principle can be used to reduce activity in sweat glands or overactive muscles.
The effect is temporary. Over time, the nerve forms new connections, muscle activity returns, and the effect gradually wears off. How long this takes varies from person to person.
Cosmetic uses: forehead lines and brow lift
In aesthetic medicine, botulinum toxin is most often used for “dynamic” lines, which appear when facial muscles move. Common areas include:
- Forehead lines — horizontal lines that form when raising the eyebrows
- Frown lines — vertical lines between the eyebrows
- Crow’s feet — lines at the outer corners of the eyes
It can also be used for a subtle eyebrow lift. By relaxing certain muscles that pull the brow downward, a doctor can allow the muscles that lift the brow to work with less resistance. The result is often described as a non-surgical brow or forehead lift, although it is not the same as a surgical lift, and the change is usually subtle.
Other cosmetic uses include softening a gummy smile, relaxing the jaw muscles in people who clench or grind their teeth, and smoothing neck bands. The right approach depends on your face, muscle strength and goals.
A skilled doctor aims for a natural look, where you still have facial expression. A good consultation should discuss what you want to change and what you want to keep.
Medical uses: excessive sweating
Botulinum toxin is also used for hyperhidrosis, a condition where people sweat much more than the body needs to regulate temperature. It can affect the underarms, palms, soles of the feet or face, and it can have a real impact on daily life, work and confidence.
As a sweaty hands treatment or for underarm sweating, small amounts of botulinum toxin are injected into the skin of the affected area. This temporarily reduces the activity of the sweat glands there. Treatment of the palms can be more uncomfortable than underarm treatment, so your doctor may discuss ways to improve comfort.
Before treatment for sweating, a doctor should check for any underlying cause, since excessive sweating can occasionally be linked to other medical conditions or medicines.
Botulinum toxin also has other medical uses, such as for chronic migraine and certain muscle conditions, but these require assessment by an appropriate specialist.
Results timeline
Results do not appear straight away. A typical timeline looks like this:
- Immediately after. You may see small bumps at the injection points, which usually settle within an hour or so.
- Days 2 to 5. Many people start to notice the effect.
- Around 2 weeks. The full effect is usually visible. Many doctors offer a review at this stage.
- Over the following months. The effect gradually wears off as muscle activity returns.
How long the results last varies between individuals and depends on factors such as the area treated, the dose, your muscle strength, your metabolism and how often you have had treatment before. No clinic can guarantee a specific duration.
Common, usually temporary side effects include:
- Mild pain, redness or swelling at the injection site
- Bruising
- Headache
- Asymmetry
- Eyelid or eyebrow drooping, if the product affects nearby muscles
Seek urgent medical help if you develop difficulty swallowing, speaking or breathing, or muscle weakness away from the treated area. These are rare but serious.
Botulinum toxin is not suitable if you are pregnant or breastfeeding, have certain neuromuscular conditions such as myasthenia gravis, have an infection at the injection site, or are allergic to any ingredient. Tell your doctor about all medicines, including some antibiotics, which can interact with it.
General aftercare often includes staying upright for a few hours, not rubbing or massaging the treated area, and avoiding strenuous exercise, saunas and facials for the rest of the day, or as your doctor advises.
Choosing a Botox clinic
Because botulinum toxin is a prescription medicine, where you go and who treats you matters. When choosing a Botox clinic in Dubai or Abu Dhabi, check that:
- The clinic is licensed by the DHA in Dubai or DoH in Abu Dhabi
- A licensed doctor assesses you and performs or supervises the treatment
- The product is genuine and approved for use in the UAE
- You have a proper consultation and give written consent
- A review appointment and aftercare are included
Be cautious about treatment offered outside licensed clinics, at parties or at unusually low prices. Counterfeit or poorly stored products can be unsafe.
Price factors
The cost of Botox treatment varies, and quotes usually depend on:
- The areas treated and how many
- The amount of product needed, which depends on muscle strength and goals
- The brand of botulinum toxin used
- The doctor’s training and experience
- Whether a review appointment is included
- Medical treatments, such as for sweating, which often need more product
If you are considering Botox in Abu Dhabi or Dubai, a consultation with a licensed doctor is the best first step.
