Rentox 100U is the standard 100-unit vial of PharmaResearch Bio’s botulinum toxin type A. Its main selling point is the formula: no albumin and no gelatin, which is unusual among Korean toxins.
What is Rentox 100U?
Rentox 100U is one vial of 100 units of freeze-dried Clostridium botulinum toxin type A, made without human serum albumin or animal gelatin. It arrives as a white freeze-dried cake.
The 100-unit size fits clinics that treat toxin patients steadily across the week and want to open only what they will use.
What is Rentox 100U used for?
Aesthetic use centers on dynamic lines in the upper face. Permitted uses depend on your country, so work within local rules.
- Frown lines and forehead lines
- Crow’s feet
- Masseter slimming
- Underarm and palm sweating
How is Rentox 100U prepared?
Check the seal and the color of the powder, then add sterile 0.9% saline slowly down the inside wall of the vial. Swirl gently rather than shaking. The solution should be clear and colorless.
Patients usually notice reduced movement from about the third day. Store sealed vials at 2 to 8 °C, away from light. Rentox 100U is for licensed medical professionals only.
