Xeomin explained: brand profile, how long results last, and Thailand vs Korea pricing

Botulinum toxin from Merz Pharma — who it suits, where it is used, and what it should cost

Quick answer

Xeomin is a botulinum toxin from Merz Pharma (Germany). It is a naked type A toxin with the complexing proteins removed, which lowers the chance of long-term immune response. Results typically last 3–4 months. Reference pricing is about 10,000–16,000 บาท per 100 units in Thailand versus roughly 7,000–12,000 บาท per 100 units in Korea. The average gap is around 25–30%, roughly 3,000 baht per vial. Registration: Thailand — Registered; Korea — Registered.

Xeomin's selling point is the removal of accessory proteins, leaving only the active molecule. In theory that means fewer triggers for antibody formation, so the people who benefit most are those injecting three or four times a year over many years.

Technically, it needs no refrigeration before reconstitution, making transport and storage stable and reducing potency loss from a broken cold chain. That matters because it dictates how firm or soft the product feels, how far it spreads and which tissue plane it belongs in. Experienced injectors pick the sub-model to match the site rather than choosing on brand name alone.

Popular placement: glabella, forehead, crow's feet and spasticity indications. Good planning starts from a whole-face assessment rather than filling only the spot the patient points at, because balance comes from distributing volume sensibly, not from maximising one area.

On longevity, Xeomin typically holds 3–4 months. It fades sooner with a fast metabolism, frequent intense exercise, smoking, highly mobile areas such as lips and perioral skin, and under-dosing relative to what the face actually needs. It lasts longer with correct plane placement, a sub-model matched to local tissue pressure, and a top-up before the effect disappears completely.

Who it suits: long-term users worried about resistance, people whose results have been shortening, and anyone wanting the most stripped-down formulation.

Not suitable or best avoided: bargain hunters, since per-unit pricing sits in the premium tier. This also covers pregnancy and breastfeeding, active infection at the injection site, and any known allergy to the product's components.

Thailand versus Korea: reference market pricing runs about 10,000–16,000 บาท per 100 units in Thailand and roughly 7,000–12,000 บาท per 100 units in Korea. The average gap is around 25–30%, roughly 3,000 baht per vial. The honest comparison includes travel cost — flights, accommodation, interpreting and time. For a single small treatment the gap rarely covers a trip; combined with several procedures in one visit, the difference starts to matter.

A less-discussed advantage is thermal stability. Where cold-chain handling is imperfect or stock travels between countries, Xeomin loses potency less readily — a bigger deal than most patients realise for smaller or upcountry clinics.

Safety and authenticity: Side effects mirror other type A toxins, and while the resistance risk is lower it is not zero. Before treatment, ask to see the sealed box and label, check the registration number against Thailand's FDA or Korea's MFDS, photograph the lot number and expiry, and have the doctor open the product in front of you. A price far below market is usually a sign of unregistered stock or over-dilution.

Bottom line: Xeomin is worth it when it is matched to a real concern, injected by a doctor who reads the whole face, and understood as a temporary result that needs maintenance rather than a one-off fix. Compare prices per unit or per cc of registered product — never a promotional price against a standard one.

Frequently asked questions

  • How long do Xeomin results last?

    Usually 3–4 months, depending on the volume used, the site treated and individual metabolism. Heavy exercisers and highly mobile areas tend to fall below the average.

  • Is the Thailand–Korea price gap significant?

    The average gap is around 25–30%, roughly 3,000 baht per vial. Reference ranges are 10,000–16,000 บาท in Thailand and 7,000–12,000 บาท in Korea per 100 units; add travel and interpreting before deciding.

  • Is Xeomin registered in Thailand and Korea?

    Compiled status: Thailand — Registered; Korea — Registered. Registration is granted per sub-model, so always inspect the actual box and verify the number with the authority before treatment.

  • How long before a top-up?

    A common approach is to reassess one to two months before the effect ends: topping up while some product remains needs less volume and keeps the result stable instead of swinging back and forth.

  • Is Xeomin right if toxin has stopped working for me?

    It is a common choice when resistance is suspected, but rule out other causes first: under-dosing, excessive dilution or poor storage.

  • Does the result differ visibly from Botox?

    In practice they are close, with roughly 1:1 unit conversion; perceived differences usually come from injector technique rather than the product.
