Brand Introduction
Rentox is a botulinum toxin type A injectable manufactured in South Korea, most consistently attributed across supplier listings to Pharma Research Bio. It's marketed in the wholesale/export channel as a "premium class" botulinum toxin — a positioning built around two specific manufacturing claims: a formulation that reportedly excludes protein stabilizers like albumin and gelatin, and a lower diffusion profile compared to other toxins on the market, meaning the effect is claimed to stay more localized to the injection site rather than spreading into surrounding tissue.
It's positioned in the same competitive tier as Botulax and other Korean-manufactured botulinum toxins — export-focused, priced for the wholesale/practitioner market, and marketed heavily through B2B trade platforms (Beautetrade, B2Brazil, Supl.biz) rather than through a polished direct-to-consumer or clinical brand presence. That distribution pattern itself is worth noting: Botulax and Elasty both have identifiable corporate parents (Hugel, Huons) with investor-facing websites, conference presences, and published trial data. Rentox does not show up the same way — its footprint is almost entirely wholesale-listing based, which is a meaningfully different evidence tier.
A handful of listings attribute Rentox to Hugel Inc. instead of Pharma Research Bio.

Product Specifications
Active ingredient: Clostridium botulinum toxin type A
Form: Lyophilized (freeze-dried) white powder; reconstituted with 0.9% saline into a colorless, transparent liquid
Available strengths: 100U, 200U
Composition: Marketing copy describes the formulation as free of albumin, gelatin, and protein stabilizers. However, at least two separate wholesale listings give a specific excipient breakdown that includes human serum albumin (0.5mg for the 100U vial, 1.0mg for the 200U vial) and sodium chloride. These two claims cannot both be true of the same product — either the "protein-free" marketing line is inaccurate, or those specific listings are describing a different/older formulation. This needs to be resolved before it goes on your page.
Onset: Reported around day 3 post-injection
Duration: Cited at roughly 6–8 months
Diffusion: Marketed as the lowest diffusion among currently known botulinum toxins — this is a strong claim with no cited data behind it in any of the available listings
Potency range: One listing cites a controlled potency fluctuation range of 191–215 units (for the 200U product), suggesting some quality-control documentation exists somewhere, even if not publicly accessible
Storage: 2–8°C
Shelf life: ~3 years under proper freeze-dried storage
FAQs
Is Rentox the same as Botox or Botulax?
No. Different manufacturer, different formulation — marketed as a lower-cost alternative within the same botulinum toxin type A category.
How fast does it work, and how long does it last?
Onset is reported around day 3, with duration cited at 6–8 months. These are manufacturer/listing claims rather than published clinical trial results, so treat them as typical ranges rather than guarantees.
Does Rentox actually contain albumin?
Unresolved. Marketing language says no; at least two specific ingredient breakdowns say yes. This is the single biggest thing to verify with your actual supplier before publishing anything definitive.
Is Rentox FDA-approved?
No indication of FDA or EMA approval in any available sourcing. References point to KFDA (Korean) approval, which is a different, and more limited, regulatory bar than what Botulax (via its FDA-approved Letybo listing) can claim.
What areas is it used for?
Facial mimic wrinkles, glabellar lines, crow's feet, neck and lip contouring are the most commonly cited cosmetic uses, alongside a broader set of therapeutic/medical indications depending on market.
Why is there so much less information on Rentox compared to Botulax or Elasty?
Rentox doesn't appear to have the same corporate-backed public presence — no dedicated manufacturer website, investor materials, or published clinical trials came up in research. Its documentation lives almost entirely in wholesale trade listings, which is a thinner evidence base than the other two products in your catalog.
