Rentox 100UI — Premium Botulinum Toxin Type A
Rentox 100UI is a botulinum toxin type A product from Pharma Research Bio in South Korea. It carries KFDA approval and has become a popular choice in clinics across Korea and Japan. Each vial contains 100 units, supplied as a fine, lyophilized powder for reconstitution.
Practitioners often note Rentox’s fast onset and extended duration compared to some other toxin brands. Because the powder is so fine, the vial can look nearly empty before dilution — this is normal.

Preparation and administration
Dilution reference
| Diluent added | Units per 0.1 mL | Total volume |
|---|---|---|
| Saline Added (100U vial) | Resulting Concentration | |
| 1.0mL | 10 units per 0.1mL | |
| 2.0mL | 5 units per 0.1mL | |
| 2.5mL | 4 units per 0.1mL | |
| 4.0mL | 2.5 units per 0.1mL |
Administration notes
Practitioners reconstitute Rentox with sterile, preservative-free 0.9% saline. A standard dilution for the 100-unit vial uses 2.5mL of saline, producing a concentration of 4 units per 0.1mL.
Once reconstituted, use the solution within 24 hours and store it refrigerated at 2–8°C in the meantime.
Dosage and technique
For glabellar lines, a common protocol uses a 30G needle to inject 0.1mL per point across 5 sites — 2 injections in each corrugator muscle and 1 in the procerus muscle — for a total of 20 units. These muscles pull the brows together and downward, contributing to deep frown lines.
- When injecting below the orbital ridge (such as for crow’s feet), place a finger beneath the ridge to help prevent the product from migrating
- Direct the needle toward the upper center of the injection point, using a controlled volume per site
- Individual response varies by metabolism, antibody status, and lifestyle factors
After treatment
- Remain upright for at least 4 hours after treatment to help prevent product migration
- Avoid touching, rubbing, or massaging the treated area for at least 24 hours
- Avoid applying makeup for 24 hours
- Avoid strenuous exercise, hot showers, saunas, and excessive sun exposure for 24 to 48 hours
- Avoid bending over or activities that cause a rush of blood to the head for up to 7 to 10 days
- Avoid antibiotics or other medications that affect blood clotting around the time of treatment, unless directed otherwise by a physician
Keeping the product within specification
- Store refrigerated at 2–8°C
- Do not freeze
- Use within 24 hours after reconstitution

Fast delivery; Easy to use product; good results @ five days !
Mine seemed to take a little longer to show the effect than I expected. It did eventually work, but personally I'd probably return to a more familiar option next time.
Worked eventually, but the onset felt a little unpredictable for me compared with what I'm accustomed to. I'd probably try another toxin before repeating it.
The parcel reached me quickly and the outer packaging was sturdier than expected. The toxin did work, but the effect developed unevenly for me during the first several days before fully settling.
Full effect took around 8 or 9 days on me. It worked fine once it kicked in, I'm just used to faster products.
It did work but mine took closer to a week to really show. I think I was just expecting it sooner based on other reviews.
Took about a week to fully see it on me. Slower than expected so taking off two stars, but yes it did work.
This was my first time trying Rentox and I'd honestly book it again.
Worked well enough. I think I simply respond faster to other toxin brands.
Glad I gave this one a shot. I'll probably stick with it for a while.
