Botox relaxes muscle. Filler adds volume. Biostimulators build collagen. They solve different problems, and most people arrive asking for the one that doesn't fix their concern.
Six categories, each with a different mechanism. Neurotoxin relaxes muscle. HA filler adds volume and reverses. Biostimulators build your own collagen slowly and don't reverse. Kybella destroys fat permanently. Hyaluronidase removes filler. And a set of therapeutic uses that aren't cosmetic at all. Which you need depends on the concern, not the brand.
Forehead lines when you raise your brows, crow's feet when you smile. That's muscle — a neurotoxin question.
A hollow under the eye, a flat cheek, a soft jawline. That's volume or structure — a filler question.
Most people have both, in different places, and the plan uses both. But this single distinction resolves more consultations than anything else — and it's why filler placed where the problem is movement never looks right, no matter how much goes in.
A third possibility: if what bothers you is colour or texture rather than shape, no injectable fixes it. That's resurfacing or pigment treatment.
Botulinum toxin blocks the signal from nerve to muscle, reducing movement in a specific area. Less movement means the lines that movement creates soften.
Lasts three to four months. Not reversible, but it wears off — which makes it the lowest-commitment injectable there is.
Beyond the standard facial areas, the same mechanism treats jaw clenching, trapezius tension, sweating, and migraine.
Gel placed beneath the skin to restore structure that's been lost or add projection that wasn't there. The result is visible the same day.
The one category that reverses. Hyaluronidase dissolves all of it, which makes HA the sensible starting point for anyone new to filler or unsure about an area.
Products differ in firmness and flexibility rather than quality — matching the property to the tissue is what determines whether it looks right.
These don't add volume — they prompt your body to make collagen over months. Nothing much happens at first, then volume develops gradually and lasts considerably longer than filler.
Not reversible. No enzyme removes Sculptra or Radiesse, which is a real reason to build across sessions rather than place a large amount at once.
Suits patients who'd rather nobody noticed a change happening, and works for body areas where filler volumes would be impractical.
Deoxycholic acid disrupts fat cell membranes, and the cells are cleared permanently. Used mainly for submental fullness — the area under the chin.
The result is permanent and irreversible. Those fat cells are gone. That's the appeal and the reason it's approached conservatively.
Swelling afterward is substantial and lasts longer than most patients expect. It also does nothing for loose skin — if the complaint is laxity rather than fat, this isn't the treatment.
The enzyme that breaks down hyaluronic acid. Used for filler that migrated, was overplaced, or simply isn't what the patient wanted.
Performed here under live ultrasound. Imaging confirms whether filler is actually present, where it has moved to, how deep it sits, and where the vessels run — rather than injecting enzyme into an estimated location.
Filler placed at other practices is routinely treated, and a significant proportion of the work here is correction.
Not cosmetic. Same medications, different purpose — and several are FDA-approved for these indications specifically.
Neurotoxin for chronic migraine, excessive sweating, jaw clenching, and plantar fasciitis. Corticosteroid for inflamed acne cysts and raised scars.
Worth knowing before treatment rather than after.
That table is the argument for starting with HA filler if you're new to injectables or uncertain about an area. It costs a little more over time than a biostimulator, and it buys you the ability to change your mind.
Patients frequently request filler for the nasolabial folds — the lines from nose to mouth — because that's where the shadow is.
But the fold is often a consequence rather than the problem. Midface volume descends, the cheek deflates, and the tissue above the fold drops onto it. Filling the fold directly treats the symptom and can make the midface look heavier.
Supporting the cheek frequently softens the fold without touching it. That's the kind of thing a consultation is for, and it's why "what would you like done" is a less useful question than "what bothers you."
Every injection here is mine — not delegated to a nurse injector or an assistant. That matters most in the cases where the right answer is less than what was asked for, or a different treatment entirely, or nothing. Those conversations are harder to have when the person holding the syringe didn't do the assessment.
What is the difference between Botox and filler?
They address opposite problems. Neurotoxin relaxes muscle, so it treats lines caused by movement — the forehead, between the brows, around the eyes. Filler adds volume, so it treats hollowing and lost structure — cheeks, lips, jawline, temples. A line that appears only when you make an expression is a neurotoxin problem. A shadow or hollow that is there when your face is completely still is a volume problem. Many patients need both, in different places.
Which injectable is right for me?
It depends on what the concern is rather than which treatment is popular. Look at your face at rest and then in movement. Anything visible only in movement is generally treated with neurotoxin. Anything visible at rest is generally a volume, texture, or skin quality issue. Volume responds to filler or biostimulators; texture and pigment need resurfacing rather than injection. This is the assessment a consultation is for.
What is the difference between filler and a biostimulator?
Hyaluronic acid filler adds volume immediately and is reversible with hyaluronidase. Biostimulators such as Sculptra and Radiesse stimulate your own collagen production over three to six months, produce gradual change, and are not reversible. Filler suits patients who want to see a result now and retain the option to undo it. Biostimulators suit patients willing to wait for something that develops slowly and lasts longer.
Which injectables can be reversed?
Only hyaluronic acid fillers, including Juvederm, Restylane, and RHA, which dissolve with hyaluronidase. Neurotoxin cannot be reversed but wears off in three to four months. Radiesse and Sculptra are not reversible. Kybella destroys fat cells permanently and cannot be undone. Reversibility is worth knowing before treatment rather than after, and it is a genuine reason to treat conservatively with the permanent options.
Can injectables treat skin texture or pigment?
No. Injectables address muscle movement and volume. Surface concerns — sun damage, pigmentation, fine texture, pore appearance, and scarring — need resurfacing or light-based treatment instead. Patients frequently request filler for a complaint that is actually a skin quality problem, and adding volume does not improve it.
Who performs injections at Plump Medical Spa?
Dr. Amir Mortazavi, MD performs every injection personally. Nothing is delegated to nurse injectors, nurse practitioners, physician assistants, or aestheticians. California law permits delegation under physician supervision, and supervision does not always mean the physician is present — which is why the distinction matters.
Can I have multiple injectable treatments in one visit?
Frequently, yes. Neurotoxin and filler are commonly performed in the same appointment, and biostimulators can often be combined with either. The sequence and spacing depend on the areas treated and are determined at consultation.
That's the normal state of affairs, and it's what the consultation is for. Sometimes the answer is a different treatment entirely, and sometimes it's nothing yet.
