Baseline Facial Vessel Tone
Placeholder: superficial facial vessels sit at normal resting diameter.
- Normal: Resting vessel tone (placeholder metric)
- Steady: Baseline flow (placeholder metric)
- Quiet: Nerve signal (placeholder metric)
- Even tone: Skin appearance (placeholder metric)
Normal vascular tone
Placeholder: healthy vessels constrict and relax within a narrow, stable range.
Neurovascular Dysregulation Mechanism
Placeholder: sensory nerve and vessel signaling loop becomes miscalibrated.
- Elevated: TRPV/TRPA activity (placeholder metric)
- Increased: Neuropeptide release (placeholder metric)
- Amplified: Vessel responsiveness (placeholder metric)
- Lowered: Threshold to trigger (placeholder metric)
Signal miscalibration
Placeholder: sensory nerve fibers over-signal to nearby dermal vessels.
Trigger-Induced Vasodilation Response
Placeholder: heat, spice, or stress rapidly widens facial vessels.
- Seconds: Response latency (placeholder metric)
- High: Dilation magnitude (placeholder metric)
- Heat, spice, stress: Common triggers (placeholder metric)
- Flushing: Visible sign (placeholder metric)
Acute overshoot
Placeholder: the vasodilation response overshoots normal proportional limits.
Persistent Erythema / Flushing Pattern
Placeholder: redness fails to fully resolve between trigger episodes.
- Prolonged: Recovery time (placeholder metric)
- Reddened: Baseline shift (placeholder metric)
- Increasing: Episode frequency (placeholder metric)
- Compromised: Skin barrier (placeholder metric)
Incomplete resolution
Placeholder: vessels stay partly dilated between successive triggers.
Chronic Vessel Dilation (Telangiectasia)
Placeholder: repeated dilation cycles leave vessels permanently widened.
- Fixed dilation: Vessel state (placeholder metric)
- Persistent: Visibility (placeholder metric)
- Low: Reversibility (placeholder metric)
- Laser therapy: Typical treatment (placeholder metric)
Structural vessel change
Placeholder: vessel walls remodel into visibly dilated, fixed telangiectasia.
Placeholder key insight: chronic hyperreactivity can leave lasting vascular marks.
