Precautions & safety
Regulatory status differs by country. Rentox is not registered or approved everywhere, and the buyer is responsible for confirming the legal status of import, supply and clinical use in the destination country before ordering.
Dose, dilution, injection technique and all clinical decisions follow the package insert and the treating clinician. Nothing on this page is dosing guidance.
Post-treatment care
- Stay upright for 4 hours
- Do not rub or massage the area for 4 hours
- Avoid heavy exercise, sauna and heat for 24 hours
It is not a dermal filler: it relaxes muscle and adds no volume, so it will not fill a static line or restore lost volume.
It is not a skin booster and does not hydrate or resurface the skin.
It is not ready to use: the vial holds freeze-dried powder and must be reconstituted before injection.
The 200-unit vial is not a stronger product than the 100-unit vial.
Rentox Botulinum Toxin (100U / 200U) FAQ
What is Rentox?
Rentox, also written ReNTox, is a purified botulinum toxin type A made by PharmaResearch Bio in South Korea. It is supplied as a freeze-dried white powder that is reconstituted with preservative-free 0.9% sodium chloride before use.
What is in the box?
One vial of freeze-dried powder in the size you select, 100 units or 200 units, with the package insert. Saline is not included.
Is Rentox 200U stronger than Rentox 100U?
No. It is the same toxin; the vial simply holds 200 units instead of 100, and needs twice the diluent to reach the same concentration. Choose the vial that matches how many units you use once it is opened, since a reconstituted vial has a short working window.
How does Rentox compare with Nabota 100U?
Both are Korean botulinum toxin type A vials we stock and both are reconstituted before use. Rentox comes from PharmaResearch Bio and is offered in a 200-unit vial as well as a 100-unit vial, which is the practical difference for clinics treating larger muscles or several patients in a session. Units are not interchangeable between brands, so compare the package inserts before switching.
Is Rentox approved in my country?
Regulatory status differs by country and botulinum toxin is a prescription-only medicine in most markets. Rentox is not registered everywhere. Confirm the legal status of import, supply and clinical use in your country before you order, and use it only within a licensed clinical setting.
Can I buy Rentox wholesale in the USA or Europe?
Yes. We ship worldwide from Seoul and handle customs clearance for US and EU orders. Contact us with your quantity and destination country for trade pricing. Payment is arranged with our team after the order is placed.

Rentox, also written ReNTox, is a botulinum toxin type A supplied worldwide from Seoul by Korean Aesthetic. It is made by PharmaResearch Bio in South Korea and offered here in two vial sizes, 100 units and 200 units, each box holding one vial of freeze-dried white powder that is reconstituted with preservative-free 0.9% sodium chloride before use.
What Rentox is used for
Rentox blocks the release of acetylcholine where nerves meet muscle, so the treated muscle relaxes for a period of months and the skin above it creases less. Clinics use it on dynamic wrinkles, meaning lines caused by movement, and on overactive muscles such as the masseter. As with other type A toxins, an effect is usually seen within a few days and is complete at around 2 weeks, results commonly last 3 to 4 months, and repeat treatments are kept at least 3 months apart.
What is in the vial, and which size to order
Rentox is purified Clostridium botulinum toxin type A supplied as a lyophilized powder, with the stabilisers listed on the package insert in the box. PharmaResearch Bio is part of the PharmaResearch group, which is also known for its Rejuran polynucleotide line. Both vial sizes hold the same toxin: the 200-unit vial is not stronger, it simply carries twice the units and needs twice the diluent to reach the same concentration. Choose the size that matches how many units you use once a vial is opened, because a reconstituted vial has a short working window and leftover units are usually wasted. Clinics treating one or two areas per patient tend to take the 100-unit vial, while those doing jawline work or several patients in a session tend to take the 200-unit vial.
How Rentox compares with the other Korean toxins we stock
Nabota 100U is another Korean botulinum toxin type A powder vial we hold, offered in the 100-unit size only. Innotox is supplied as a ready-to-use liquid, so there is nothing to reconstitute, where Rentox is a powder and must be mixed. Units are not interchangeable between toxin brands, so compare the package inserts before switching. The full range is in our botulinum toxins collection.
How Rentox is administered
Rentox is injected by a trained, licensed medical professional. Reconstitution volume, dose in units, depth and placement follow the manufacturer's instructions for use and the judgement of the treating clinician; Korean Aesthetic publishes no dosing or dilution guidance beyond what is printed on the insert in the box. Add the saline slowly down the side of the vial and swirl gently rather than shaking, and check that the reconstituted solution is clear and colourless before use. Keep unopened vials refrigerated at 2-8 °C and away from light; keep a reconstituted vial refrigerated and use it within 24 hours. Many clinics also keep a topical anaesthetic on hand for patient comfort.
