Rentox 100U

Rentox is PharmaResearch Bio's botulinum toxin type A, and the 100-unit vial is the everyday presentation. PharmaResearch is better known internationally for its PN skin booster line, and Rentox is the company's move into the toxin category — which shows in the formulation choices rather than in the marketing. The one that matters to most buyers is the stabiliser. Rentox is made without albumin or gelatin, which puts it in a small group of Korean toxins alongside Innotox. For clinics whose patients ask what is actually in the vial, that is usually the reason the order lands here rather than on a conventional albumin-stabilised product like Botulax. It ships as a lyophilised white powder and is reconstituted with sterile saline before use — the standard format, and the reason it travels and stores as robustly as it does. Why practitioners choose Rentox 100U Formulated without albumin or gelatin The stabiliser system avoids human serum albumin and animal-derived gelatin. This is the practical differentiator, and it is a formulation fact rather than a performance claim. Contained spread PharmaResearch Bio positions Rentox on low diffusion from the injection point. Treat that as the manufacturer's own characterisation — but limited spread is genuinely what matters in the periorbital area and anywhere a millimetre changes the result. Onset within the first few days Most patients notice reduced movement from around day three, with the effect settling over the following week to two weeks. The right size for a mixed list One hundred units covers a full upper-face session comfortably without leaving much behind on a quieter week. Clinics running heavier masseter and body work generally move to Rentox 200U, where the cost per unit is lower. What it is used for The everyday aesthetic applications are glabellar lines, horizontal forehead lines and lateral canthal lines, plus masseter reduction for lower-face contouring and perioral work. It is also used for axillary and palmar hyperhidrosis. Therapeutic uses include blepharospasm and limb spasticity. Which of these are approved indications depends entirely on the market you practise in, and treatment should sit inside your own scope of practice and clinical judgement. Composition The active ingredient is Clostridium botulinum toxin type A at 100 units per vial. It acts by blocking acetylcholine release at the neuromuscular junction, producing temporary and fully reversible relaxation of the injected muscle. The preparation is formulated without albumin or gelatin. Rentox 100U specifications Product name Rentox 100U Manufacturer PharmaResearch Bio Country of origin South Korea Content 100 units per vial Format Lyophilised powder, 1 vial per box Preparation Reconstitution with sterile 0.9% sodium chloride required Appearance once reconstituted Clear, colourless solution Storage 2-8 °C, sealed and protected from light Handling Check that the seal is intact and the cake is white to slightly off-white before use. Reconstitute with sterile 0.9% sodium chloride, introducing the diluent gently down the wall of the vial rather than shaking — the active is a protein and mechanical stress degrades it. Diluent volumes and per-site dosing follow PharmaResearch Bio's prescribing information supplied with the box, not a protocol carried across from a different brand. Use reconstituted solution promptly and keep it refrigerated in the meantime. Duration of effect for most patients runs to roughly three to six months, varying with dose, treated area, muscle bulk and individual metabolism. This is a prescription product for administration by trained, licensed practitioners only. It is contraindicated in pregnancy and breastfeeding, in known hypersensitivity to any component, where infection is present at the intended injection site, and in neuromuscular disorders such as myasthenia gravis. How it compares Rentox 100U Botulax 100U Innotox 100U Manufacturer PharmaResearch Bio Hugel Medytox Format Powder Powder Ready-to-use liquid Stabiliser Albumin-free Human serum albumin L-methionine, polysorbate 20 Reconstitution Required Required Not required If albumin-free is the deciding factor, Rentox and Innotox are the two to compare — Innotox additionally removes the reconstitution step, at a higher price. Storage and shipping Rentox ships from Seoul in insulated cold-chain packaging with coolant and is held between 2 and 8 °C in transit. Refrigerate on arrival, keep vials sealed until use, and never freeze.
