The Pulsed Dye Laser (PDL) is a highly effective and low risk laser for the treatment of a wide range of vascular lesions. PDL releases brief pulses of selectively absorbed optical radiation which can cause selective damage to pigmented structures (blood vessels) and cells. The PDL is used to treat port-wine stains, facial telangiectasias and haemangioma. Newer PDLs with longer wavelengths and extended pulse durations have made deeper tissue penetration possible and improved clinical outcomes with reduced risk. PDL treatments are performed with a topical anaesthetic.
- Reduced redness by causing necrosis in the targeted capillaries
- Reduced scar volume (height)
- Reducing itch
- Improved pliability
- Improved pigmentation
Effects of PDL are not necessarily permanent and multiple sessions may be needed depending on the severity/volume of the area.
- Mild swelling (resolves itself)
- Mild purpura (bleeding)
- Transient dyspigmentation (darker/lighter skin colour)
- Vesiculation (very rare)
