Myobloc in Newport Beach: An Expert Alternative for Botox Resistance
New to Myobloc? Read the full guide to Botox resistance and Type B toxin in Newport Beach — why resistance develops, how it's confirmed, and what to expect from Myobloc — before booking.
Type B botulinum toxin for patients who no longer respond to Botox, Dysport, or Xeomin. Administered personally by Dr. Amir Mortazavi, MD.
Botox, Dysport, Xeomin, and Jeuveau are all Type A botulinum toxins. If you've developed neutralizing antibodies to Type A, switching between those brands won't help — they share the same target. Myobloc is Type B, a structurally distinct serotype, which is why it can work when Type A no longer does.
Starting at $500 per treatment area.
Available for the following expression zones:
Forehead Lines (1 area) — horizontal lines across the forehead caused by repeated brow elevation.
Glabella (1 area) — the vertical "elevens" between the eyebrows that create a tense or fatigued appearance at rest.
Crow's Feet (1 area) — fine lines fanning from the outer corners of the eyes, most visible when smiling or squinting.
Multiple areas can be treated in the same session. Dr. Mortazavi will advise how many areas your concern actually requires — which is sometimes fewer than patients expect.
This is for you if: your neurotoxin used to work and progressively stopped · you've switched brands within Type A with no improvement · your results now last only a few weeks · you're not getting the same effect at doses that previously worked
What's different about Type B: onset is typically faster than Type A. Duration is often shorter. Dosing is measured on an entirely different scale, so unit counts are not comparable — a Myobloc dose looks nothing like a Botox dose on paper.
Consultation required before treatment. Not every case of "Botox stopped working" is antibody-mediated resistance. Underdosing, product dilution, injection technique, and unrealistic expectations account for many of them, and those are cheaper problems to fix. Dr. Mortazavi will determine which situation you're in before recommending Type B.
Myobloc is not carried by most medical spas. Stock is limited.
What Is Myobloc, and Why Are People in Newport Beach Asking About It?
If your Botox isn’t lasting like it used to—or if your results have become inconsistent—you may be experiencing neurotoxin resistance. At Plump Medical Spa, in Newport Beach, we offer Myobloc: a powerful, doctor-administered solution designed for clients who no longer respond to traditional botulinum toxins like Botox, Dysport, or Xeomin.
Why Choose Myobloc Over Botox?
Myobloc (rimabotulinumtoxinB) is a Type B neurotoxin, while Botox is Type A. This chemical difference makes Myobloc an excellent alternative for individuals who’ve built immunity to Type A products.

Works even if you’ve built up Botox resistance
May kick in faster
Offers smoother results in previously “stubborn” areas
Allows rotation between neurotoxins for long-term planning

FAQs: Myobloc in Newport Beach
Q: Is Myobloc stronger than Botox?
Myobloc isn’t stronger or weaker—it’s different. It uses a different protein structure (Type B) and is ideal for clients resistant to traditional neurotoxins.
Q: How fast does Myobloc work?
You may start seeing effects in 2–3 days, slightly faster than Botox in many cases.
Q: Is it safe to rotate between Myobloc and Botox?
Yes, rotating between toxins can be a healthy way to reduce immune response and prolong effectiveness.
Q: Does Myobloc hurt more than Botox?
Some patients report slightly more sensitivity at the injection site, but numbing cream and proper technique reduce this significantly.
Q: Is Myobloc FDA-approved?
Yes—for therapeutic uses like cervical dystonia. Its cosmetic use is off-label but backed by peer-reviewed studies.
