Coretox: Does Botox Resistance Really Happen?
The real reason Botox resistance develops is due to complexing proteins — and Coretox eliminates them, so results stay consistent even with repeated procedures.
Does Botox Really Become Less Effective the More You Get It?
💡 Before You Read — Quick Q&A
Q. I've heard that the more Botox you get, the more resistant your body becomes until it stops working altogether. Is Coretox any different?
A. Resistance to conventional Botox doesn't develop against the pure neurotoxin itself — it's triggered by the complexing proteins surrounding it, which prompt your immune system to produce antibodies. Coretox is formulated without these complexing proteins, which significantly lowers the likelihood of resistance developing, even with repeated procedures.
Q. So how exactly is Coretox different from regular Botox?
A. The difference lies in the formulation. Both contain the same active neurotoxin that delivers results, but Coretox removes the unnecessary protein complexes that conventional Botox leaves intact.
"By eliminating the complexing proteins that trigger resistance, Coretox maintains consistent results across repeated procedures — making it our top recommendation at Beautystone for patients committed to long-term care."
— Dr. Wi Young-jin (Beautystone Clinic, Seoul)
What Is Coretox?
Coretox (manufactured by Medytox) is a botulinum toxin type A formulation that
eliminates the complexing proteins found in conventional products
and isolates only the pure neurotoxin (150 kDa),
making it a highly refined Botox-class procedure.
While conventional Botox formulations combine the active toxin with complexing proteins,
Coretox uses a "pure neurotoxin-only" structure by removing those protein complexes entirely —
and that distinction makes all the difference.
Botox Resistance? It Was a Protein Problem All Along
"After years of Botox, it just stopped working for me" —
it's one of the most common things I hear in the consultation room.
But here's something important to understand:
most people don't actually know
what causes Botox resistance in the first place.
The botulinum toxin itself — the core neurotoxin
that blocks nerve signals (the 150 kDa neurotoxin) —
is actually quite resistant to antibody binding on its own.
The real culprit is the complexing proteins (non-toxic proteins)
that surround it in conventional formulations.
These proteins act like "background noise,"
prompting your immune system to identify them as foreign substances
and begin producing antibodies.
As those antibodies accumulate,
they can attack or neutralize the toxin itself —
leading to the frustrating experience of "Botox that just doesn't work anymore."
To be straightforward about it:
conventional Botox formulations have always been used
without fully removing these complexing proteins.
Coretox takes a fundamentally different approach.
It starts by removing the complexing proteins entirely,
leaving only the pure neurotoxin behind.
This dramatically reduces the "trigger" that gives your body a reason to form antibodies.
It's not simply a brand difference —
the molecular structure that initiates immune responses
has been fundamentally changed.
Now, it's worth noting —
not everyone develops Botox resistance.
It varies depending on individual physiology, treatment frequency, and dosage,
and the time it takes for resistance to develop differs from person to person.
That said, if you're getting Botox two to three times a year or more,
or managing multiple areas simultaneously — such as wrinkles, masseter, and calves —
your cumulative exposure is anything but small.
For patients like these,
choosing a formulation designed to minimize resistance risk
is simply the smarter long-term strategy.
👨⚕️ Key Takeaway from Dr. Wi Young-jin:
Botox resistance doesn't start with the toxin itself —
it begins when your body forms antibodies against the surrounding complexing proteins.
Coretox is a pure neurotoxin formulation with those complexing proteins removed,
which means results are far less likely to diminish with repeated procedures.
At Beautystone, this is precisely why we recommend Coretox
to patients who are committed to maintaining their Botox results over the long term.
Coretox vs. Conventional Botox — What's Actually Different?
There's a common misconception worth clearing up:
Coretox is not stronger, nor does it last longer.
The duration of effect and degree of muscle relaxation
are comparable to conventional Botox.
The difference isn't about how long a single treatment lasts —
it's about consistency over time, the ability to stay effective without diminishing returns.
Category | Conventional Botox | Coretox |
|---|---|---|
Contains complexing proteins | Yes | Removed |
Likelihood of antibody formation | Relatively higher | Relatively lower |
Single-session efficacy | Equivalent | Equivalent |
Efficacy with repeated procedures | May decline with accumulated resistance | Relatively stable |
Best suited for | Short-term or one-time treatment | Long-term, ongoing management |
Of course, every patient is different —
but here's how I generally approach the decision.
If you're getting Botox fewer than twice a year and treating just one area,
conventional Botox can absolutely deliver excellent results.
On the other hand, if you're regularly managing multiple areas —
wrinkles, masseter, calves, trapezius muscles, and so on —
or if you've already noticed that results "don't seem to last as long as they used to,"
Coretox is very likely the more strategic choice for you.
We've seen quite a few patients who had diminishing results from treatments elsewhere
switch to Coretox at our clinic and regain satisfying results within two to three sessions.
Frequently Asked Questions
Q1. I think I may have already developed Botox resistance. If I switch to Coretox, will it start working again?
A. If antibodies have already formed,
switching to Coretox won't immediately reverse your resistance.
However, since Coretox contains no complexing proteins,
it reduces further immune stimulation,
and as existing antibody levels gradually decrease,
efficacy may return over time.
A realistic approach is to monitor your response over two to three sessions after making the switch
and reassess from there.
Q2. Is Coretox more expensive? How often do I need to get it?
A. Because the manufacturing process is more precise and refined,
Coretox does come at a slightly higher cost than conventional Botox.
The recommended interval between sessions is typically four to six months,
and the duration of effect itself is not significantly different from conventional Botox.
Over the long term, however, the reduced risk of resistance
may mean fewer repeat procedures become necessary —
making the cost-to-benefit ratio well worth considering.
Q3. Are there side effects with Coretox? Anything I should watch out for?
A. It's important to be clear — Coretox isn't without considerations.
As a botulinum toxin-based procedure,
temporary reactions such as Swelling, Bruising, or headaches
are possible, similar to those seen with conventional Botox.
Additionally, pregnant or breastfeeding patients,
as well as those with neuromuscular conditions,
must consult with a physician before undergoing any Botox procedure.
That said, because complexing proteins have been removed,
allergic reactions and immune-related side effects
are reported to occur less frequently compared to conventional formulations.
I always recommend a thorough consultation before making your decision. This has been Dr. Wi Young-jin.
