Platysmal bands: what causes them,
What the platysma
actually is
The platysma is a broad, thin, rectangular sheet of muscle sitting directly beneath the skin of the front and sides of the neck. It arises from the fascia over the chest and shoulder, and its fibres ascend obliquely upward and inward, crossing the clavicle, up the neck.
At the top, it inserts onto the lower border of the mandible, into the skin of the lower face, into the corner of the mouth, into the orbicularis oris, and along the depressor anguli oris. So the muscle is not only in the neck. It attaches into the muscles of the lower face, which explains why what happens in the neck affects the whole lower face.

Why the platysma also pulls
the whole lower face down
- Jowling, by pulling downward on the jawline and upper neck
- Marionette lines, because its fibres blend with the depressor anguli oris
- Deepening nasolabial and malar folds through downward pull on midfacial tissues
- A shorter, wider-reading neck through its action on the mandible
Two different bands,
two different mechanisms
Medial bands
Lateral bands
Why the platysma is so thin,
and what that changes
When bands are a sign
of something else
- Sudden or rapid appearance of a band that does not correlate with expression
- A firm lump in the neck, related to the band or separate from it
- Difficulty swallowing, changes in voice, or unexplained neck pain
- A history of thyroid disease or symptoms of it
- Recent unintended weight loss
- New pressure or tightness in the neck at rest
Two things worth
saying plainly
What a neck bands
assessment covers
- Whether the bands are medial, lateral, or both, at rest and on tension
- Whether the pattern is consistent with absent midline decussation
- Extent and depth of banding, and how far they extend from jaw to collarbone
- Skin quality, thickness and laxity across the neck
- Fat distribution above and below the platysma, since submental fullness changes what an approach can achieve
- Jawline continuity and any jowling that reads as connected to the neck finding
- Marionette lines and lower face position, since the platysma contributes to both
- Presence of horizontal neck lines as a separate finding
- Chin projection, since a receded chin makes bands more prominent
- Medical history, including thyroid disease and recent weight change
- Whether anything is clinically appropriate, including the option of nothing, and whether a surgical or medical assessment is the appropriate course
What to know before
your consultation
Factors that may make an approach inadvisable
- Pregnancy or breastfeeding
- Active infection or inflammation over the neck
- Certain neuromuscular conditions, including any history of difficulty swallowing
- Certain medications, including blood thinning medication
- Significant skin laxity or established heavy jowling, where a surgical opinion is the appropriate course
- Sudden or unexplained change in the neck, which should be medically assessed first
- Untreated thyroid disease
- Expectation of removing bands entirely by non-surgical means
- Unrealistic expectations about achievable change

Questions patients
ask
Neck bands are the visible edges of the platysma muscle. In youth, the two halves of the muscle join at the midline of the neck. With age, that central connection weakens and the medial edges separate, becoming visible as vertical cords during expression.
Anatomy from birth. About 10 per cent of people are born without any midline join between the two halves of the platysma. Only necks with no decussation produce true medial vertical bands, and those patients tend to show prominent banding earlier and more starkly, regardless of age.
Stand in front of a mirror, relax your face, then pull the corners of your mouth downward or grimace as though disgusted. If two vertical cords appear from around the jawline down toward the collarbone, the muscle mechanism is present. If the neck stays smooth under tension, banding is unlikely to be your main issue.
Not necessarily. Bands and skin laxity are different findings, though they often coexist. The literature also notes bands often recur after traditional facelifts because the aging, thin platysma cannot hold well with mastoid fascia fixation. A surgical opinion is appropriate where laxity is dominant, and this is discussed at consultation.
No. The muscle producing the band sits up to a centimetre beneath the skin surface, and no topical formulation reaches the muscle layer. Skincare improves how the skin reads overall but does not address the mechanism.
No, and they can make them worse. Exercise strengthens muscle. The platysma is already contracting too much. Reinforcing it works in the wrong direction.
Yes. Contraction of the platysma pulls the whole lower face down, deepens nasolabial and marionette lines, and contributes to jowling. That is why the neck, jawline and lower face are assessed together.
If a band appeared suddenly, if there is a firm lump, if you have difficulty swallowing or a voice change, if you have thyroid symptoms or recent unintended weight loss, or if the neck feels tight or under pressure at rest. Those need a medical assessment first.
