Neurotoxin to the platysma, injected personally by Dr. Amir Mortazavi, MD.
The platysma is a broad, thin sheet of muscle running from the collarbone up across the neck to the jawline. With age it loses its even tone and separates into vertical cords — the bands that stand out when you tense your neck, grimace, or speak.
Relaxing those bands softens the cords and smooths the neck contour.
It also pulls down on your jawline, which most patients don't realize.
Because the platysma attaches along the jaw, its downward pull works directly against the muscles that define the jawline. Relaxing it releases that tension and allows the jaw border to sit slightly higher and appear cleaner.
This effect is sometimes called a Nefertiti lift. It's subtle — a softening of the downward pull rather than an actual lift — but for patients whose main complaint is a jawline losing definition, addressing the neck is frequently the missing piece.
What this treats — and what it doesn't.
Does: vertical bands and cords that appear when the neck is tensed · the downward pull on the jawline · horizontal neck lines caused by muscle activity
Doesn't: loose or excess skin · crepey texture · horizontal lines etched from skin quality rather than movement · fullness under the chin · significant laxity
The self-check. Look in a mirror and clench your teeth or grimace hard.
Vertical cords stand out → platysmal bands. This treatment.
Skin looks loose or crepey but nothing cords up → a skin quality problem. See Sculptra for the neck or CO2 laser for the neck.
Softness or fullness under the chin → Kybella or surgery.
Skin you can grasp and lift → surgical. No injectable addresses that, and Dr. Mortazavi will tell you so rather than treating toward a result this can't produce.
Most necks have more than one component. The assessment determines which parts are treatable here.
What to expect: injections placed along the length of each band. About 15 to 20 minutes. Onset day 3 to 5, full effect around two weeks. Duration is typically three to four months.
The neck warrants more caution than facial areas. The platysma sits over muscles involved in swallowing and neck movement. Excessive dosing or product spreading beyond the intended plane can cause temporary difficulty swallowing or neck weakness. It resolves — but it lasts as long as the treatment does.
Dosing is deliberately conservative and injections are placed superficially along the band rather than deep. This is performed by Dr. Mortazavi personally.
