PULSED DYE LASER (PDL)

The Pulsed Dye Laser (PDL) is a specialist medical laser that targets blood vessels in the skin using a concentrated beam of yellow light. It is widely used in dermatology to treat conditions that cause redness, broken blood vessels, or vascular birthmarks.

As a Consultant Dermatologist in London, Dr Kentley has extensive training in medical and cosmetic use of this laser, and the assessment of suitable skin conditions for its use.

What Can Pulsed Dye Laser Help With?

PDL treatment may be recommended for:

  • Rosacea-associated redness

  • Thread veins and broken blood vessels (telangiectasia)

  • Facial flushing

  • Port-wine stain birthmarks

  • Spider angiomas

  • Certain vascular scars or marks

  • Redness after acne or surgery

How Pulsed Dye Laser Works

  • The PDL emits a wavelength of light that is absorbed by haemoglobin (the red pigment in blood).

  • This light energy selectively destroys abnormal or unwanted blood vessels without damaging surrounding skin.

  • The body gradually reabsorbs the treated vessels, leading to a clearer, more even skin tone.

What to Expect from Treatment

  • A consultation is required to assess suitability and discuss treatment goals.

  • The procedure is performed in a specialist outpatient clinic, usually in a 30 minute appointment.

  • Patients often describe a mild snapping sensation as the laser is applied.

  • Treated areas may appear red or bruised temporarily, usually settling within a few days.

  • Multiple sessions may be needed for the best results, depending on the condition.

Aftercare and Recovery

  • Mild redness, swelling, or bruising can occur and typically resolves within 5–10 days.

  • A gentle skincare routine and broad-spectrum sunscreen are recommended after treatment.

  • Avoiding heat and intense exercise for 24–48 hours may help reduce temporary redness or swelling.
