A lot of men start their research with the phrase "Xeomin vs Allergan," and the framing itself causes confusion. Allergan (now part of AbbVie) is the pharmaceutical company that manufactures Botox. Botox is the product; Allergan is the maker. So the genuine, apples-to-apples comparison is Xeomin vs Botox, two separate brands of the same class of medicine: botulinum toxin type A.
This guide clears up that mix-up and gives you what actually matters when you are deciding which toxin to choose at a Bangkok clinic: how the two compare on dosing, onset, how long results last, side effects, who should avoid them, and what they realistically cost in Thai baht. It is written for male physiology, because men typically have stronger, bulkier facial muscles and thicker skin than women, which changes the dosing and the goal of treatment.
Both Xeomin and Botox are prescription medicines. Neither should be bought, dosed, or injected without an in-person consultation and assessment by a licensed medical injector. Nothing below is a substitute for that consultation.
Xeomin and Botox: same drug class, different brands
Botulinum toxin type A is a purified protein that temporarily blocks the nerve signal telling a muscle to contract. Relax the muscle that creases the skin and the overlying line softens. That single mechanism is shared by every brand on the market. The brands differ mainly in how the molecule is formulated and packaged.
Botox (onabotulinumtoxinA), made by Allergan/AbbVie (USA). This is the original cosmetic botulinum toxin and the most studied brand worldwide. The active toxin is bundled with surrounding "accessory proteins" (sometimes called complexing proteins) that come from the manufacturing process. It first received US FDA approval for medical use in 1989 and specifically for cosmetic frown lines (the glabella) in 2002, so the cosmetic track record runs a little over two decades, not "30 years" as is often loosely claimed.
Xeomin (incobotulinumtoxinA), made by Merz (Germany). Xeomin uses the same core toxin but strips away those accessory proteins, which is why it is marketed as a "naked" or purified toxin. The theoretical advantage is a potentially lower chance of the immune system producing neutralising antibodies over years of repeat treatment, which would otherwise make the toxin gradually stop working. Xeomin also does not require refrigeration before reconstitution, a minor logistics point.
A practical detail the marketing often skips: Xeomin and Botox are dosed at approximately a 1:1 unit ratio. One unit of Xeomin does roughly the same work as one unit of Botox. That matters because it makes per-unit and per-area pricing directly comparable between the two, unlike Dysport (a different brand dosed at roughly 2.5 to 3 units per 1 unit of Botox).
Plain-language glossary. *Accessory proteins:* extra proteins packaged around the active toxin; Xeomin removes them. *Antibody resistance:* when the immune system learns to neutralise the toxin so treatments work less well over time; this is uncommon in cosmetic dosing but is the main theoretical reason some long-term users prefer Xeomin.
What the evidence actually says about "which lasts longer"
This is where the older version of this article went wrong, claiming Botox "sometimes lasts slightly longer." The honest, evidence-based answer is that neither brand reliably outlasts the other, and the right summary depends on what you are treating.
For medical conditions, the two are broadly interchangeable at a 1:1 dose. A prospective open-label cross-over study in cervical dystonia (Dressler and colleagues, 2013) found near-identical treatment duration for incobotulinumtoxinA (Xeomin) and onabotulinumtoxinA (Botox), with both falling inside the predefined therapeutic-equivalence range. Broader experience in conditions such as blepharospasm points the same way.
For cosmetic upper-face use, the picture is less settled. At least one head-to-head study (Prager and colleagues, 2015) found Botox modestly outperformed Xeomin at a strict 1:1 ratio for upper-face wrinkles, and some clinicians respond by dosing Xeomin slightly higher to match. There is also basic-science data suggesting incobotulinumtoxinA may carry marginally lower per-unit biological activity. None of this is a knockout difference, and you may equally see a manufacturer-linked study pointing the other way. For most men the practical gap is small.
For cosmetic use, both brands typically:
Begin working in 3 to 7 days. Some men notice a change as early as day 2 to 3.
Reach full effect at around 2 weeks. This is when any touch-up should be assessed, not before.
Last about 3 to 4 months on the upper face, with a realistic range of 3 to 6 months depending on the area, the dose, and your metabolism. Strong, frequently used muscles (and many men's muscles are strong) can metabolise the toxin faster, sometimes shortening duration.
The bottom line: do not choose on a "lasts longer" claim in either direction. Choose based on the right indication, an accurate dose, and a skilled injector, because those decide your result far more than the brand on the vial.
Quantified results: what men can realistically expect
Glabella (frown lines between the brows): in pivotal cosmetic trials, a large majority of treated patients reached "none or mild" wrinkle severity at peak effect (around 2 to 4 weeks), versus a small minority on placebo. Men often need a higher dose here because the corrugator and procerus muscles are bulkier.
Forehead lines: softened, not erased. The goal in men is usually to keep some natural movement so the brow does not look heavy or surprised.
Crow's feet (lateral eye lines): reliably softened; results are dose-dependent.
Masseter / jawline slimming (off-label cosmetic use): visible slimming of the lower face typically appears over 4 to 8 weeks as the chewing muscle reduces in bulk, and can last longer than upper-face treatment, often 4 to 6 months, because the dose is higher.
"Results" in men should mean refreshed, not frozen. A masculine-preserving approach uses conservative dosing in the forehead to avoid the smooth, feminised, or expressionless look.
Men-specific dosing: why your unit count is usually higher
Average male facial muscles are larger and stronger than female ones, and male skin is thicker. Across most clinics, men tend to need more units per zone than the textbook female ranges to get an even, lasting result. Typical indicative unit counts (your injector will tailor these):
Treatment zone | Typical unit range (men) | Notes for male anatomy |
Glabella (frown lines) | 20 to 40 units | Bulky corrugator/procerus; under-dosing fades fast |
Forehead lines | 10 to 20 units | Dose conservatively to keep brow natural |
Crow's feet (per side) | 8 to 15 units | Dose-dependent softening |
Masseter / jaw slimming (per side) | 20 to 50 units | Higher dose; results build over weeks |
Underarm sweating (hyperhidrosis, per side) | ~50 units | Medical indication; long-lasting relief |
Because the unit count drives the price, men should expect to pay toward the upper end of any "per area" range. This is the single biggest reason a generic price quote can mislead.
Cost in Bangkok: real THB pricing (and how it compares)
Bangkok is one of the best-value places in the world for genuine, FDA- or Thai-FDA-approved botulinum toxin, largely because clinic overheads and consultation fees are lower than in the West while injector skill is high. Pricing is quoted two ways: per treated area (a flat package for a zone) or per unit (you pay for exactly how many units are used, which is more transparent for men needing higher doses).
Brand | Per unit (THB) | Per area (THB) | Approx. US/UK equivalent | Notes |
Xeomin (Merz, Germany) | ~180 to 300 | ~9,000 to 15,000 | ~2 to 3x higher | "Naked" toxin; 1:1 with Botox |
Botox (Allergan/AbbVie, USA) | ~200 to 350 | ~10,000 to 18,000 | ~2 to 3x higher | Most-studied brand; premium pricing |
*Indicative ranges only; confirm exact pricing at consultation.* For context, the same Botox treatment that costs THB 10,000 to 18,000 per area in Bangkok commonly runs the equivalent of two to three times that in the US, UK, or Australia.
What drives your final price:
Units used, not "areas." A man treating bulky frown muscles may use 30+ units; a per-area quote can understate the real cost. Per-unit pricing is fairer here.
Brand. Xeomin is usually slightly cheaper per unit than Botox at the same clinic.
Number of zones. Forehead, glabella, and crow's feet together cost more than one zone.
Injector seniority and whether the price is for an aesthetic doctor or a senior dermatologist.
Consultation fee and whether it is credited toward treatment (ask; at many clinics it is).
Touch-ups. A 2-week review touch-up may or may not be included; clarify before you book.

Who should NOT have Botox or Xeomin (contraindications)
Botulinum toxin is very safe in trained hands, but it is genuinely not for everyone. Tell your doctor about your full medical history. You should avoid treatment, or be treated only with specialist caution, if any of the following apply:
Neuromuscular disorders such as myasthenia gravis, amyotrophic lateral sclerosis (ALS), or Lambert-Eaton syndrome, where the toxin can dangerously amplify muscle weakness.
Known allergy to botulinum toxin or to any ingredient in the specific formulation (for example human albumin).
Active skin infection or inflammation at the planned injection site.
Pregnancy or breastfeeding. Safety has not been established, so treatment is not recommended.
Certain medications, especially aminoglycoside antibiotics (such as gentamicin) and other agents that interfere with neuromuscular transmission, which can potentiate the toxin's effect. Bring a current medication list.
A history of bleeding disorders or use of strong blood thinners increases bruising risk and should be discussed.
This list is not exhaustive. Only an in-person assessment can confirm whether toxin is appropriate for you.
Procedure and recovery timeline
A typical male toxin appointment is quick:
Consultation and mapping (10 to 20 minutes). The injector assesses your muscle strength, animation pattern, and goals, then plans dose and injection points.
Cleansing and optional numbing. A topical anaesthetic or ice may be used; most men find the injections very tolerable.
Injection (about 5 to 10 minutes). A series of tiny injections with a fine needle into the mapped muscles.
Done. You can usually return to work the same day.
Aftercare (the first 24 hours matter most):
Stay upright for about 4 hours. Do not lie flat or have a massage facing down.
Do not rub or press the treated area, which can move the toxin to unintended muscles.
Avoid strenuous exercise, alcohol, saunas, and intense heat for about 24 hours.
Gently animate the treated muscles in the first hour if your injector advises it.
Onset begins in 3 to 7 days; full effect at about 2 weeks. Book any touch-up review at the 2-week mark, not sooner.
Side effects and red flags
Common and temporary (usually resolve in hours to a few days):
Redness, minor swelling, or small bruises at injection sites
Mild headache after forehead or glabella treatment
A feeling of tightness or heaviness as the muscle relaxes
Less common, usually self-limiting (resolve over weeks):
Eyelid or brow droop (ptosis) from toxin spreading to nearby muscles, often from rubbing the area or from imprecise placement
Asymmetry (one side relaxing more than the other), correctable with a small touch-up
A temporarily "heavy" or "surprised" brow if the forehead is over- or under-dosed
Seek urgent medical care if, in the days after treatment, you develop difficulty swallowing, slurred speech, trouble breathing, generalised muscle weakness, or visual disturbance. These signs of toxin spread beyond the injection area are rare with correct cosmetic dosing but must be assessed immediately.

Choosing a safe clinic in Bangkok (and spotting red flags)
The biggest real-world risk is not the molecule. It is counterfeit or improperly stored product, and unqualified injectors. Bangkok has excellent clinics and some that are not. Protect yourself:
Confirm the product is genuine and Thai-FDA-approved. Ask to see the sealed Botox or Xeomin vial and its hologram/batch label before reconstitution. Genuine Allergan and Merz vials carry verifiable authenticity features.
Insist on a licensed doctor injector, not a technician or a beautician.
Be wary of prices that look too good to be true. A 50-unit "Botox" promotion at a fraction of the going rate is a flag for diluted, grey-market, or counterfeit toxin.
A real clinic requires a consultation and takes a medical history. If a venue will inject you with no questions asked, leave.
Ask where the vial is stored and how it is reconstituted. Toxin must be handled and stored correctly.

Xeomin vs Botox: side-by-side comparison
Feature | Xeomin (incobotulinumtoxinA) | Botox (onabotulinumtoxinA) |
Maker / origin | Merz, Germany | Allergan / AbbVie, USA |
Formulation | "Naked" toxin, accessory proteins removed | Toxin with accessory proteins |
Unit dosing | ~1:1 with Botox | Reference standard |
Onset | 3 to 7 days | 3 to 7 days |
Peak effect | ~2 weeks | ~2 weeks |
Typical duration | ~3 to 4 months (range 3 to 6) | ~3 to 4 months (range 3 to 6) |
Antibody-resistance theory | Potentially lower long-term risk | Low, but theoretically possible |
Evidence vs each other | Broadly equivalent in medical use; cosmetic head-to-head data are mixed (one study favoured Botox at strict 1:1) | Broadly equivalent in medical use; modest cosmetic edge in one upper-face study at 1:1 |
Bangkok price (per area) | ~THB 9,000 to 15,000 | ~THB 10,000 to 18,000 |
Best fit | Frequent re-treaters; anyone wanting a purified toxin or who suspects resistance | Men who want the most-studied brand and predictable, well-documented results |
So which should a man choose?
For most men, either brand will give an excellent result when the injector is skilled and the product is genuine. Use the indication, not the hype:
Lean toward Xeomin if you re-treat often (several times a year), you want the purified "naked" toxin, or a previous course of toxin seemed to stop working over time (a possible sign of antibody resistance). It is also usually a little cheaper.
Lean toward Botox if you value the longest cosmetic track record and the largest body of published data, and predictable, well-characterised behaviour matters to you. Where the two have been compared directly for upper-face wrinkles, Botox has shown a slight edge at a strict 1:1 dose, though many clinicians simply nudge the Xeomin dose up to match.
The brand is a smaller variable than dose accuracy, injection technique, and a masculine-preserving treatment plan. That is what determines whether you look refreshed or frozen.
This is a prescription medical treatment. A licensed Menscape doctor will confirm your suitability, map your dose to your male anatomy, and recommend the right brand for your goals at an in-person consultation. Book a Botox consultation at Menscape Bangkok to compare Xeomin and Botox for your face.
Frequently Asked Questions
Is Xeomin the same as Botox?
No. They are two distinct brands of botulinum toxin type A. Botox (onabotulinumtoxinA) is made by Allergan/AbbVie in the USA; Xeomin (incobotulinumtoxinA) is made by Merz in Germany. Calling either one 'the other's Botox' is incorrect. Xeomin is a purified, accessory-protein-free toxin, while Botox includes those accessory proteins.
Is 'Allergan' a type of Botox?
No. Allergan (now part of AbbVie) is the pharmaceutical company that manufactures Botox. Botox is the product name; Allergan is the maker. The correct comparison is Xeomin vs Botox, not 'Xeomin vs Allergan'.
Which lasts longer, Xeomin or Botox?
Neither reliably outlasts the other. In medical-condition studies they perform comparably when dosed at the same 1:1 unit ratio, with both typically lasting about 3 to 4 months (range 3 to 6). In cosmetic upper-face use the head-to-head data are mixed, with one study (Prager 2015) finding Botox modestly outperformed Xeomin at a strict 1:1 ratio. The practical difference is small, and injector skill matters more than the brand.
Do men need more units than women?
Usually yes. Male facial muscles are typically larger and stronger and male skin is thicker, so men often need higher unit counts per zone to get an even, lasting result. Because price tracks units, men should expect to pay toward the upper end of any per-area quote, which is why per-unit pricing is more transparent.
How much do Xeomin and Botox cost in Bangkok?
Indicatively, Xeomin runs about THB 9,000 to 15,000 per area (roughly THB 180 to 300 per unit) and Botox about THB 10,000 to 18,000 per area (roughly THB 200 to 350 per unit). That is commonly two to three times cheaper than the US or UK. Confirm exact pricing at consultation, as the final figure depends on how many units you actually need.
Who should not get Botox or Xeomin?
Avoid treatment if you have a neuromuscular disorder (such as myasthenia gravis, ALS, or Lambert-Eaton syndrome), a known allergy to the toxin or formulation, an active skin infection at the injection site, or if you are pregnant or breastfeeding. Tell your doctor about all medications, especially aminoglycoside antibiotics, which can amplify the toxin's effect. Only an in-person assessment can confirm suitability.
When will I see results and how long do they take to peak?
Most men notice softening within 3 to 7 days, with full effect at about 2 weeks. Any touch-up should be assessed at the 2-week review, not earlier, because the toxin is still taking effect before then.
Can I switch between Xeomin and Botox?
Yes. Because they are dosed at roughly a 1:1 unit ratio, switching is straightforward and a licensed injector can move you between them. Some men switch to Xeomin if they suspect their results have been fading earlier over time, which can occasionally indicate antibody resistance.
Will Botox make me look frozen or feminised?
Not if it is dosed correctly. A masculine-preserving plan uses conservative forehead dosing so you keep natural movement and a strong brow. The goal for men is to look refreshed and less tired, not expressionless. Technique and dose matter far more than which brand you choose.
How do I make sure the product is genuine in Bangkok?
Ask to see the sealed, labelled Botox or Xeomin vial with its authenticity features before it is reconstituted, confirm the brand is Thai-FDA-approved, insist on a licensed doctor injector, and be suspicious of prices far below the market rate, which can signal diluted or counterfeit toxin. A legitimate clinic always takes a medical history and requires a consultation.
