Every practice says natural. The question worth asking is who's actually holding the needle — and at most medical spas in Orange County, it isn't a physician.
From $250 per area — forehead, frown lines, or crow's feet. Onset begins day 3 to 5, full effect at day 10 to 14, duration three to four months. Botox, Dysport, Xeomin, and Letybo are all type A toxins and work the same way; the differences are modest. Every injection at Plump Medical Spa is performed personally by Dr. Amir Mortazavi, MD — not a nurse injector, physician assistant, or aesthetician.
Search for Botox in Newport Beach and every result will promise natural, subtle, never-frozen results. The claim is universal, which means it tells you nothing.
Here is a question that does distinguish practices: who will physically be injecting you?
At most medical spas in Orange County, the answer is a registered nurse, nurse practitioner, or physician assistant working under physician supervision. That's legal in California and frequently very good care. Many nurse injectors are excellent.
It simply is not what happens here. Dr. Mortazavi performs every injection himself, every visit — and the person who assessed your face is the person who treats it and the person who sees how it settled at follow-up.
Over a single appointment, an experienced injector of any credential can do good work. Over years, something else determines the outcome: whether anyone is tracking your cumulative treatment.
The overfilled or overly frozen appearance almost never comes from one bad appointment. It develops gradually, across providers, with nobody watching the total — a few more units each visit, a syringe added here and there, and no single person holding the picture across five years.
Seeing the same physician is the thing that catches that drift.
All four are botulinum toxin type A. All work the same way, by interrupting the nerve signal that tells a muscle to contract. The differences between them are real but modest, and no one of them is meaningfully better than the others.
Product selection is based on treatment area, prior response, and your history. If you've done well on a particular product before, that carries real weight — there's no reason to change something that's working.
The most common reason patients feel their neurotoxin "didn't work" is not a bad product or a bad injector. It's under-dosing — receiving fewer units than the muscle actually required.
This happens for a straightforward commercial reason. Some practices quote per-area pricing built around a low unit count, which makes the treatment look competitive on a price list and underdelivers in the mirror. The patient concludes Botox doesn't really work for them.
Muscle mass varies considerably between patients, and men generally require meaningfully more than women. You'll be told what your treatment involves before it happens, rather than discovering at week three that it wasn't enough.
Over-treatment produces the frozen appearance everyone is trying to avoid — and it's not correctable. There's no way to remove neurotoxin once it's placed; you wait three months.
Adding a small amount at a two-week follow-up is straightforward. That asymmetry is the reason for starting conservatively rather than aiming for maximum effect on day one.
All four products on this page are type A toxins. If you've developed neutralizing antibodies to type A, they share the same target — changing brands within the category does nothing.
Myobloc is a type B toxin, structurally distinct, and it works when type A no longer does. Very few practices in Orange County carry it.
That said, most cases of "it stopped working" turn out to be under-dosing rather than antibody resistance — and that's a cheaper problem to fix. Dr. Mortazavi will determine which situation you're actually in before recommending type B. More on Botox resistance →
Neurotoxin treats dynamic lines — lines caused by muscle movement, which appear when you make an expression. It does not treat lines etched into the skin at rest, and it does not treat volume loss.
Most faces need some combination. If several areas are involved, facial balancing assesses the face as a structure rather than treating areas one at a time.
The patients I worry about aren't the ones who got too much in one appointment. They're the ones who've been treated by six different injectors over eight years, where each visit was reasonable and nobody was tracking the total. That drift is invisible until it isn't — and by then it's a longer conversation than it needed to be.
Who injects the Botox at Plump Medical Spa?
Dr. Amir Mortazavi, MD performs every injection personally. Treatment is not delegated to nurse injectors, nurse practitioners, physician assistants, or aestheticians. At most medical spas in Orange County the injector is not a physician, which is legal in California and often good care — it simply is not what happens here.
What is the difference between Botox, Dysport, and Xeomin?
All are botulinum toxin type A and all work the same way. Dysport tends to have slightly faster onset and spreads a little more, which suits broad areas such as the forehead. Xeomin contains no accessory proteins, which some patients prefer, particularly those concerned about developing resistance. Botox has the longest track record. Letybo is a newer type A option. Product choice is based on treatment area, prior response, and patient history.
How long does Botox take to work?
Onset typically begins day 3 to 5, with full effect at day 10 to 14. Judging the result before two weeks is not useful — the muscle is still relaxing. Duration is typically three to four months.
How much does Botox cost in Newport Beach?
At Plump Medical Spa treatment starts at $250 per area, with areas being forehead, frown lines, and crow's feet. Pricing for all treatments is published openly on the treatment menu rather than quoted only at consultation.
Why did my Botox stop working?
The most common reason is under-dosing rather than resistance — receiving fewer units than the muscle required. Genuine antibody-mediated resistance to type A toxin does occur, and in that case switching between Botox, Dysport, and Xeomin will not help because all three are type A. Myobloc is a type B toxin and works when type A no longer does.
Will Botox make me look frozen?
Not at appropriate dosing. A frozen appearance results from over-treatment — too much product, or treating muscles that should have been left alone. Conservative dosing with reassessment at two weeks produces softened lines while preserving expression. Adding a small amount later is straightforward; removing excess is not possible.
How many units of Botox will I need?
It depends on muscle strength, which varies considerably between patients. Men generally require more than women because facial muscle mass is greater. Under-dosing is the most common cause of a disappointing result, and you will be told what your treatment involves before it happens.
What areas can be treated with Botox?
Common areas include forehead lines, glabellar frown lines, and crow's feet. Additional areas include bunny lines on the nose, a lip flip, downturned mouth corners, the masseter for jaw slimming and grinding, platysmal neck bands, the trapezius, and underarms for excessive sweating.
What should I avoid after Botox?
Stay upright for four hours, avoid rubbing or massaging the treated area, and skip strenuous exercise for 24 hours. Mild redness or small bumps at injection sites typically resolve within an hour.
It's a fair question anywhere, and it's the one that actually distinguishes practices. Here the answer is always the same.
