Mapping Visible Telangiectasia Before Treatment
Placeholder: visible red vessels are mapped before laser or IPL treatment begins.
- 0.1–1mm: Typical vessel size (placeholder metric)
- Cheeks/nose: Common location (placeholder metric)
- I–IV: Skin types treated (placeholder metric)
- Photography: Pre-treatment step (placeholder metric)
Identifying target vessels for treatment planning
Placeholder text: clinicians map visible capillaries prior to selecting laser parameters.
Selective Photothermolysis — Targeting Without Damaging Skin
Placeholder: selective photothermolysis heats a chromophore while sparing surrounding tissue.
- ~ms: Thermal relaxation time (placeholder metric)
- Pulse duration: Key parameter (placeholder metric)
- Anderson & Parrish: Concept origin (placeholder metric)
- Selective damage: Goal (placeholder metric)
Matching pulse duration to vessel thermal relaxation time
Placeholder text: pulse duration is matched to vessel size for selective heating.
Hemoglobin Chromophore Absorption of Laser and IPL Light
Placeholder: hemoglobin absorbs specific wavelengths more than surrounding tissue.
- 532/585/1064nm: Key wavelengths (placeholder metric)
- Oxyhemoglobin: Chromophore (placeholder metric)
- ~577nm: Absorption peak (placeholder metric)
- Laser / IPL: Device type (placeholder metric)
Wavelength selection for hemoglobin-specific absorption
Placeholder text: chosen wavelengths favor hemoglobin absorption over melanin.
Thermal Coagulation and Closure of Dilated Capillaries
Placeholder: absorbed heat coagulates vessel walls, closing the capillary.
- ~70°C: Coagulation temp (placeholder metric)
- Collapse: Vessel response (placeholder metric)
- Days–weeks: Healing time (placeholder metric)
- Purpura fades: Visible sign (placeholder metric)
How coagulated vessels are cleared by the body
Placeholder text: closed capillaries are gradually resorbed by the body.
Multiple Session Treatment Protocols for Full Clearance
Placeholder: full clearance usually needs several spaced treatment sessions.
- 3–5: Typical sessions (placeholder metric)
- 3–4 weeks: Session interval (placeholder metric)
- 50–75%: Clearance rate (placeholder metric)
- Annual touch-up: Maintenance (placeholder metric)
Planning a multi-session course for durable results
Placeholder text: sessions are spaced to allow healing between treatments.
Placeholder highlight: consistent sessions improve long-term vessel clearance.
