Botox (botulinum toxin type A) is a neurotoxin protein purified from the Clostridium botulinum bacterium. When injected into target muscles in micro doses, it temporarily blocks nerve-muscle transmission; as a result dynamic wrinkles are reduced, excessive sweating is controlled, and chronic migraine attacks are alleviated. Its effect begins within 3–7 days, lasts an average of 4–6 months, and with its FDA-approved safety profile it is the world's most frequently performed non-surgical aesthetic procedure.
What Exactly Is Botox?
Botox is the purified, medically adapted form of type A among the seven different neurotoxin serotypes (A–G) produced by the Clostridium botulinum bacterium. The term "Botox" is actually a registered trademark of Allergan; however, in everyday language it is used as an umbrella term for all botulinum toxin injections.
Brief History
| Year | Development |
|---|---|
| 1820 | German physician Justinus Kerner first described the effects of botulinum toxin |
| 1949 | The toxin's ability to block the neuromuscular junction was discovered |
| 1980 | Dr. Alan Scott performed the first clinical use for strabismus treatment |
| 1989 | FDA approved Botox for strabismus and blepharospasm |
| 2002 | FDA granted approval for cosmetic use (glabellar lines) |
| 2010 | Chronic migraine indication was added |
| 2024–2025 | More than 9 million treatments performed annually worldwide |
How Does Botox Work? (Mechanism of Action)
The action of botulinum toxin A occurs in three stages:
- Binding: The toxin binds to specific receptors (SV2 protein) on motor nerve endings.
- Internalisation: It is taken into the cell via endocytosis.
- SNARE protein cleavage: Inside the cell it cleaves the SNAP-25 protein, blocking acetylcholine release. Without acetylcholine the muscle cannot contract; the result is temporary relaxation of the target muscle.
This process is reversible. Nerve endings form new connections (axonal sprouting), restoring muscle function within 4–6 months. This is why Botox causes no "permanent damage" and needs to be repeated at regular intervals.
Where Is Botox Applied?
Aesthetic Treatment Areas
| Area | Target Concern | Average Units |
|---|---|---|
| Forehead | Horizontal lines | 10–30 units |
| Glabella (between brows) | "11 lines" | 15–25 units |
| Crow's feet (eye corners) | Smile lines | 8–16 units |
| Nose bridge (bunny lines) | Nose wrinkles | 4–8 units |
| Upper lip (lip flip) | Gummy smile / thin lip appearance | 4–6 units |
| Chin (mentalis) | Orange-peel texture | 4–8 units |
| Platysma bands (neck) | Neck bands / Nefertiti lift | 20–40 units |
| Masseter muscle | Square jaw slimming, teeth grinding | 25–50 units (per side) |
Medical Treatment Areas
- Chronic migraine: In patients experiencing headaches 15+ days per month, approximately 155 units injected into 31 points reduce attack frequency and severity. FDA approved.
- Hyperhidrosis (excessive sweating): Applied to the underarms, palms, and soles to block acetylcholine stimulation of sweat glands. Effect can last up to 6–12 months.
- Overactive bladder (OAB): Injected into the bladder muscle under cystoscopy guidance to reduce involuntary contractions.
- Spasticity: Applied to target muscle groups in post-stroke or cerebral palsy-related muscle stiffness.
- Bruxism (teeth grinding): Injected into the masseter and/or temporalis muscle to reduce daytime and nighttime teeth clenching and grinding.
- Cervical dystonia: A primary treatment option for involuntary contraction of neck muscles.
- Blepharospasm: Used for involuntary eyelid closure.
- Stomach Botox (endoscopic): Aims to extend the feeling of fullness in obesity treatment by relaxing stomach muscles; however its long-term efficacy remains debated.
Botox Brands: What Determines the Choice?
All products on the market contain the same active ingredient (botulinum toxin), but they differ in formulation, diffusion area, and unit equivalency:
| Brand | Manufacturer | Toxin Type | Key Feature |
|---|---|---|---|
| Botox (onabotulinumtoxinA) | Allergan (AbbVie) | Type A | Most widely used, most studied; reference standard |
| Dysport (abobotulinumtoxinA) | Galderma | Type A | Wider diffusion area; advantageous in large areas such as the forehead |
| Xeomin (incobotulinumtoxinA) | Merz | Type A | Contains no complexing proteins; lower risk of antibody resistance |
| Jeuveau (prabotulinumtoxinA) | Evolus | Type A | Developed exclusively for cosmetic use |
Unit equivalency note: 1 unit of Botox is not equal to 1 unit of Dysport. Dysport generally requires 2.5–3 times more units. When comparing brands, focus on clinical effect rather than unit count.
How Is Botox Performed? (Step-by-Step Process)
Pre-Treatment Preparation
- Consultation: The physician assesses your facial anatomy, expression patterns, and expectations.
- Medication check: Blood thinners (aspirin, ibuprofen, omega-3) should be stopped 7 days before the procedure (with physician approval).
- Alcohol: Avoid alcohol consumption 24–48 hours before the procedure.
- Make-up: Do not apply make-up to the treatment area on the day of the procedure.
The Procedure
- The treatment area is cleaned with an antiseptic solution.
- A topical anaesthetic cream (lidocaine) is applied optionally; most patients do not need it.
- Micro injections are made into the target muscles using a very fine needle (30–32 gauge).
- The procedure takes 10–20 minutes in total.
- Patients can return to their normal activities the same day.
Post-Procedure Rules (First 24–48 Hours)
- Do not touch or rub the injection area for 4 hours.
- Avoid strenuous exercise, saunas, steam baths, and hot showers for 24 hours.
- Do not lie face down for 4–6 hours; keep your head upright.
- You may apply ice to the injection area (reduces the risk of bruising).
- Delay alcohol consumption for 24 hours.
Botox Duration of Effect and Timeline
| Time | What Happens? |
|---|---|
| 0–24 hours | No visible change; toxin is binding to nerve endings |
| 2–3 days | First mild effects begin to be felt |
| 7–14 days | Full effect settles; results are assessed during this period |
| 2–3 months | Peak period; muscle is at maximum relaxation |
| 4–6 months | Effect gradually diminishes; muscle function returns |
| Month 6+ | A new session can be planned |
Research shows that in long-term regular Botox users, muscles become "trained" and the interval between sessions can gradually lengthen.
Side Effects and Risks of Botox
Common and Temporary Side Effects
- Mild redness, swelling or bruising at the injection site (resolves within 1–3 days)
- Mild headache (first 24 hours)
- Sensitivity at the injection point
Rare Side Effects
- Eyelid drooping (ptosis): Caused by the toxin spreading to adjacent muscles; occurs in 1–5% of cases and resolves spontaneously within 2–6 weeks.
- Brow drooping: May occur with incorrect dosing or injection point selection.
- Asymmetry: More common with inexperienced practitioners.
Serious (Very Rare) Side Effects
- Difficulty swallowing (dysphagia) — especially with neck injections
- Allergic reaction (anaphylaxis — extremely rare)
- Spread of toxin to distant muscles (systemic botulism — practically not seen at clinical doses)
Who Should Not Have Botox? (Contraindications)
Botox should not be applied in the following situations:
- Known allergy to botulinum toxin or any component of the formulation
- Pregnancy and breastfeeding (insufficient safety data)
- Active infection or inflammation at the injection site
- Neuromuscular diseases (myasthenia gravis, Lambert-Eaton syndrome, ALS)
- Use of aminoglycoside antibiotics or muscle relaxants (risk of interaction)
- Bleeding disorders or those receiving high-dose anticoagulant therapy
Antibody Resistance: Why Does Botox Lose Effectiveness in Some People?
With repeated treatments, it is possible for the body to develop neutralising antibodies against botulinum toxin. In this case the Botox effect lasts a shorter time with each session or does not occur at all.
Risk factors: High doses, frequent injections (more often than every 3 months), booster doses.
Recommended solutions:
- Wait at least 3 months between sessions.
- Use the lowest effective dose possible.
- Formulations free of complexing proteins (e.g. Xeomin) can be tried.
- A brand change may be considered if resistance is suspected.
What Is Preventive Botox (Baby Botox)?
Popularised in recent years among individuals in their 20s and 30s, "baby Botox" or "preventive Botox" refers to treatment using half or a third of the standard dose.
Purpose: To gently limit muscle movement before wrinkles deepen, preventing dynamic lines from becoming permanent.
Who is it suitable for?
- Individuals who have no wrinkles at rest but develop prominent lines during facial expressions.
- Those who want to preserve natural expression.
- First-time Botox users who are concerned about a "frozen face" appearance.
What Is the Difference Between Botox and Filler?
These two procedures are frequently confused but work through completely different mechanisms:
| Feature | Botox | Dermal Filler |
|---|---|---|
| Mechanism of action | Relaxes the muscle | Adds volume to create fullness |
| Target | Dynamic wrinkles (caused by movement) | Static wrinkles, volume loss, contouring |
| Active ingredient | Botulinum toxin | Hyaluronic acid, calcium hydroxylapatite, etc. |
| Duration of effect | 4–6 months | 6–18 months (depending on filler type) |
| Treatment areas | Primarily upper face | Mid-lower face, lips, jawline |
| Reversibility | Wears off naturally | HA fillers can be dissolved with hyaluronidase |
In many aesthetic plans, Botox and filler are used together (liquid facelift). Botox for the upper face combined with filler for the mid-lower face provides comprehensive rejuvenation.

7 Botox Myths vs Facts
| Myth | Fact |
|---|---|
| "Botox freezes the face and makes it expressionless" | When applied at the correct dose, natural expressions are preserved. A "frozen face" is the result of overdosing or incorrect technique. |
| "Botox is a poison and harmful to the body" | Medical Botox is the toxin diluted billions of times. Over 35 years of clinical use has proven its safety. |
| "Once you start you cannot stop" | There is no physical dependency. When you stop, your face returns to its pre-treatment state — it does not look worse. |
| "Botox accumulates and is dangerous long-term" | The toxin does not accumulate in the body. The protein injected in each session is fully metabolised within 4–6 months. |
| "Botox is only for older people" | Preventive Botox can be applied in one's 20s. Medical indications such as migraine and hyperhidrosis are independent of age. |
| "Any doctor can do Botox" | Legally physicians may administer it, but a dermatologist, plastic surgeon, or medical aesthetics specialist with expertise in facial anatomy is recommended. |
| "Results are seen immediately" | Effects begin 2–7 days later; full results settle at 10–14 days. |
How to Choose the Right Botox Practitioner
- Check the area of specialisation: Should be a dermatologist, plastic surgeon, or aesthetic medicine specialist.
- Ministry of Health-approved clinic: Verify that the centre holds an official licence.
- Request before-and-after photos: Review real results from their own patients.
- Product verification: Confirm with your own eyes that the product to be used is original, sealed, and within its expiry date.
- Value the consultation: Avoid any practitioner who proceeds directly to injection without listening to you or performing a facial analysis.
Frequently Asked Questions (FAQ)
Does Botox hurt?
The needles used are very fine (30–32 gauge). Most patients describe the procedure as "a slight prick." A topical anaesthetic cream can be applied on request.
How many days does Botox take to work?
The first effects begin within 2–3 days. Full results settle within 10–14 days. Results should not be assessed before day 14.
How long does Botox last?
An average of 4–6 months. Duration varies depending on the individual's metabolic rate, muscle mass, dose applied, and lifestyle.
Can I exercise after Botox?
Strenuous exercise, running, and weightlifting should be avoided for 24 hours after treatment. Light walking is fine.
Can Botox be applied to pregnant women?
No. Botox should not be administered during pregnancy or breastfeeding. There are insufficient safety studies in humans.
Will my facial expressions remain natural?
When applied at the correct dose by an experienced physician, natural expression is preserved. A "frozen face" is the result of excessive dosing, not an inevitable effect of Botox.
What happens if I stop Botox?
No adverse effect occurs. Muscle function gradually returns and your face returns to its natural pre-treatment state. You will not look "worse."
Can Botox and filler be done in the same session?
Yes. Many aesthetic specialists apply Botox to the upper face and filler to the mid-lower face in the same session. This approach is known as a "liquid facelift."
Does the brand of Botox matter?
Yes. Botox, Dysport, Xeomin and Jeuveau have different formulations. There are differences in diffusion area, onset of effect, and risk of antibody resistance. Your physician will recommend the most appropriate brand for you.
From what age can Botox be performed?
FDA approval is for individuals aged 18 and over. Preventive (baby) Botox can be started in one's 20s; however, individual assessment is essential.
