Pulsed Dye Laser (PDL)

Why Pulsed Dye Laser (PDL)?

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.

Main improvements

  • 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.

Adverse effects

  • Mild swelling (resolves itself)
  • Mild purpura (bleeding)
  • Transient dyspigmentation (darker/lighter skin colour)
  • Vesiculation (very rare)
  • Crusting/scabbing
  • Scarring

F.A.Q.

Is Pulsed Dye Laser (PDL) treatment suitable for all types of scars?

Pulsed Dye Laser (PDL) is primarily suitable for scars with vascular components, such as those with redness or purple discoloration due to vascular lesions. It is effective for reducing scars caused by conditions like port-wine stains, small blood vessels on the face, and hemangiomas. However, for scars primarily characterized by other factors, such as texture changes or pigmentation, PDL may be less suitable.

How many Pulsed Dye Laser (PDL) sessions are usually needed for noticeable improvements in scars?

The number of PDL sessions required for noticeable improvements in scars can vary depending on factors such as the severity and size of the scars, as well as the individual skin response to the treatment. Generally, multiple sessions are recommended, often ranging from 3 to 6 sessions, with intervals of 6 to 8 weeks between each session.

What can I expect during and after PDL treatment for scars?

During PDL treatment for scars, you can expect the skin to be locally numbed to minimize discomfort. The laser emits short pulses of light that are selectively absorbed by the blood vessels, which may cause a mild sensation of discomfort or warmth during the procedure. After the treatment, you might experience redness, swelling, and possibly a slight tingling sensation in the treated areas, but these side effects usually resolve within a few days to a week. It is important to follow your provider's aftercare instructions, such as avoiding direct sun exposure and using specific skincare products.
