MYOBLOC IN LOS ANGELES: 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 Los Angeles Asking About It?
If your Botox results aren’t lasting like they used to—or if your expression lines are no longer responding—you may be experiencing neurotoxin resistance. At Plump Medical Spa, just a short drive from Los Angeles, Beverly Hills, and Santa Monica, we offer Myobloc: a physician-only injectable solution designed specifically for those who no longer respond to traditional botulinum toxins like Botox, Dysport, or Xeomin.
Plump is one of the only medical practices in Southern California that consistently carries Myobloc (rimabotulinumtoxinB) for both cosmetic and functional treatments.
Why Choose Myobloc Over Botox?
Myobloc is a Type B neurotoxin, while Botox, Dysport, and Xeomin are Type A. This structural difference makes Myobloc an excellent choice for clients who’ve built up antibodies to Type A products.

FAQs: MYOBLOC IN LOS ANGELES
Is Myobloc stronger than Botox?

How fast does Myobloc work?
You may notice visible effects within 2–3 days, slightly faster than traditional Botox.
Does Myobloc hurt more than Botox?
Some patients experience mild sensitivity during injection, but numbing and technique make the experience very comfortable.
