Linetox is a botulinum toxin type A made in South Korea and distributed internationally, sold as a freeze-dried product in a 100-unit vial. The manufacturer states 99% purity (by SE-HPLC) and a molecular weight around 900 kDa. It is a straightforward high-purity export toxin, and the official guide is below for your records.

What is Linetox, and what are its stated specs?

Linetox is a 100-unit, freeze-dried botulinum toxin type A made in South Korea and distributed internationally (for example, by Maria Trading). The white to pale-yellow product dissolves to a clear solution. On paper, the manufacturer’s specs are tidy: 99% purity by SE-HPLC, a molecular weight around 900 kDa, and a pH of 6.0 plus or minus 0.5.

The manufacturer also reports a 36-month shelf life when stored at 2 to 8°C, with MFDS potency held within 90 to 115% of the label. Read those as the maker’s stated specifications. Linetox positions itself as a clean, high-purity export toxin rather than around any single novel feature, which makes its spec sheet the main thing to understand.

Log Notes. This explains what Linetox is and its stated specs, not how to use it. It gives no doses, units, dilution, injection points, depth, or frequency, all of which live in the official guide and belong to a licensed professional. Nothing here is medical advice, and this is not a do-it-yourself procedure.

How does botulinum toxin type A work?

It temporarily relaxes the targeted muscle. Botulinum toxin type A acts by blocking acetylcholine release at the neuromuscular junction, the chemical signal that tells a muscle to contract. The American Academy of Dermatology’s overview of botulinum toxin describes how this temporarily softens movement in the treated area, with results easing over weeks to months as nerve signaling returns.

Two honest notes on Linetox specifically. It is less independently studied than longtime names, and it is not FDA-approved, so its evidence base rests largely on the manufacturer’s spec sheet rather than broad published trials. Its brand recognition is also lower than that of Botulax or Nabota. None of that makes it good or bad; it just means the data behind it is thinner, which a professional should weigh.

What should you expect, and what is worth tracking?

A clear timeline and a careful record. The relaxing effect builds over days, then fades over weeks to months, so session-to-session comparison is what shows the pattern. For broader context, our overview of what Botox can do and the note on how long does Botox last set realistic expectations.

What should that record hold? Start with how long results lasted for you. The averages you read come from large groups, and your own duration may sit higher or lower. Note the date the effect began to ease and count back to your last session to find your personal range, which matters more here than any spec sheet.

Photos earn their place only when they stay consistent. Keep the same angle, the same lighting, and a neutral expression each time, ideally at a similar hour. A matched before-and-after pair beats memory or a flattering mirror moment. Because Linetox is less independently studied, your own consistent record carries unusual weight.

Add a short self-rating before your next appointment and always note the brand and batch. Score how relaxed the area still feels and whether you would repeat the same plan. With a thinner published evidence base, recording exactly which product was used is what lets you compare Linetox fairly against another toxin if you ever switch.

This is the cycle Dosefi is built to track. Add Linetox as a treatment, log each session with a date and photo, set a reminder for when results tend to ease, and let your self-rated notes build a trend over time. Because the published evidence here is thinner, an honest personal record is especially worth keeping.

A grounded takeaway

Linetox is a high-purity Korean botulinum toxin type A with a tidy spec sheet but a thinner independent evidence base, and it is not FDA-approved. Treat its purity and stability numbers as stated specs, keep a dated record, and leave candidacy, dosing, product choice, and the procedure to a licensed professional.
