Rentox is PharmaResearch Bio's botulinum toxin type A, supplied in 100-unit and 200-unit vials. Shipped worldwide from Seoul.
PharmaResearch is better known internationally for its PN skin booster line, and Rentox is the company's entry into the toxin category. What distinguishes it is a formulation decision rather than a marketing one: it is made without human serum albumin and without animal-derived gelatin, which puts it in a small group of Korean products alongside Innotox.
For most clinics that is the whole reason the order lands here. Patients increasingly ask what is in the vial, and an albumin-free answer is easier to give than an explanation of why albumin is used. Everything else about Rentox is conventional — lyophilised powder, reconstituted with sterile saline, stored between 2 and 8 °C.
The Rentox range
The standard vial and the sensible place to start. One hundred units covers a full upper-face session without leaving much behind on a quieter week, which makes it the right size for a mixed list or for trialling the brand against whatever is already in your fridge.
The volume vial. Same manufacturer, same formulation, twice the fill and a lower cost per unit. It earns its place where unit counts climb quickly — masseter reduction, calf slimming, trapezius contouring — or simply where the list is full enough that a 100-unit vial means opening a second box mid-session.

The formulation is identical between the two, so this is purely a throughput decision. An opened vial has a limited working life, and product discarded costs more than the saving on a larger box.
Storage and shipping
Both vials require 2-8 °C storage, sealed and protected from light. We ship from Seoul in insulated cold-chain packaging with coolant and track transit so the product arrives within its temperature range. Refrigerate on arrival; never freeze.
Buying Rentox from MY SKIN KOREA
We source Rentox directly through Korean supply channels, so what reaches your clinic is authentic product in original Korean packaging with a full remaining shelf life. Compare against the rest of our botulinum toxin range — Nabota, Meditoxin and Coretox are the closest alternatives. Many clinics add numbing cream to a toxin order, or consolidate dermal fillers into the same shipment to spread freight cost.
Clinic and distributor pricing is available through wholesale. For stock, lead times or questions about shipping to your market, contact our team.
These are professional-use products, supplied to licensed practitioners, clinics and registered distributors.
