What is the best laser therapy for treating telangiectasias (spider veins) on the face?

Best Laser Therapy for Treating Facial Spider Veins

Pulsed Dye Laser (PDL) is the treatment of choice for facial telangiectasias (spider veins), with current models using 595 nm wavelength, larger spot sizes, and longer pulse durations for optimal results. 1

Laser Options for Facial Telangiectasias

• PDL is the gold standard for treating facial telangiectasias due to its preferential absorption by hemoglobin and minimal risk of scarring 1
• Current PDL technology uses a wavelength of 595 nm with larger spot sizes (up to 10 mm) and higher fluences, allowing deeper penetration and more effective treatment 1, 2
• Longer pulse durations (1.5 ms or greater) facilitate the treatment of larger vessels, improving efficacy compared to older short-pulse models 2
• Dynamic cooling delivered to the skin before the laser pulse has made treatment safer and less painful 3

Treatment Considerations

• For facial telangiectasias specifically, PDL shows better results treating smaller vessels in upper skin regions 4
• Nd:YAG laser (1064 nm) may be more effective for deeper or larger vessels but is generally better suited for lower extremity vessels rather than facial telangiectasias 4
• Multi-wavelength approach combining 595-nm PDL followed by 1064-nm Nd:YAG can be considered for resistant cases, as PDL can target shallow vessels while Nd:YAG targets deeper components 5
• For smaller facial vessels (<0.75 mm), frequency-doubled Nd:YAG laser (532 nm) with longer pulse durations (10 ms) may also be effective 6

Pain Management During Treatment

• Cold air skin cooling is superior to ice gel analgesia in reducing pain during nonablative laser procedures on the face 3
• PDL treatment with cold air cooling is more comfortable and associated with fewer thermal side effects 3
• Regional nerve blocks can be considered for more extensive treatments, as they have been shown to be superior to topical anesthesia for patient-perceived pain during facial laser procedures 3

Potential Complications and Precautions

• Complications of laser treatment include atrophic scarring and hypopigmentation, particularly in individuals with darker complexion 3, 1
• Lasers can occasionally induce ulceration, though this is rare and seen more commonly in rapidly proliferating vascular lesions 3
• Multiple treatment sessions may be required for optimal results, typically spaced 6 weeks apart 2
• Ethyl chloride should be used with caution for analgesia before laser therapy as it is flammable and has been associated with burns 3

Treatment Protocol

• For optimal results with PDL, settings typically include:
  • Wavelength: 595 nm
  • Pulse duration: 1.5-10 ms (longer for larger vessels)
  • Fluence: 9.5-20 J/cm² (depending on vessel size and depth)
  • Spot size: 7-10 mm 1, 2, 5
• Multiple treatments (typically 2-3 sessions) spaced 6 weeks apart yield better results than single treatments 2
• Cold air cooling should be employed during treatment to reduce discomfort and thermal side effects 3
