Advanced vascular laser treatment for birthmark management and cosmetic care

What it is

A port-wine stain (PWS) is a congenital vascular birthmark caused by dilated capillaries close to the skin surface. It appears as a flat pink, red, or purple patch at birth and tends to darken, thicken, and become nodular with age. PWS most commonly affects the face, neck, and limbs, but it can occur anywhere on the body.

Unlike other birthmarks, port-wine stains do not fade naturally. Left untreated, they may lead to cosmetic disfigurement, bleeding nodules, or associated conditions such as glaucoma or Sturge-Weber syndrome.

The pulsed-dye laser (PDL) is the gold standard treatment for port-wine stains. “Staged” means that multiple sessions are required over months or years, gradually lightening the lesion. PDL works by emitting yellow light at 585–595 nm, which is absorbed by hemoglobin in blood vessels, causing selective destruction of abnormal capillaries while sparing surrounding skin.

Why it’s done

PDL treatment for port-wine stains is performed for both medical and aesthetic reasons.

✔ Cosmetic improvement – Visible facial stains often cause social and psychological distress.

✔ Prevention of progression – Without treatment, stains darken and thicken, sometimes developing nodules that bleed easily.

✔ Functional benefit – Port-wine stains near the eyes may be linked to glaucoma; treatment forms part of broader management.

✔ Early intervention in children – Pediatric treatment is encouraged to prevent resistance, as vessels become more difficult to treat with age.

✔ Quality of life – Patients experience improved confidence and reduced stigma.

Alternatives

Although staged pulsed-dye laser is the preferred treatment, alternatives exist.

→ Observation – Leaving the birthmark untreated, though it usually worsens with time.

→ Camouflage makeup – Specialized cosmetics can cover lesions but do not address the cause.

→ Other lasers:

• Nd:YAG laser (1064 nm) – Useful for deeper vessels but carries a higher risk of scarring.
• Alexandrite laser (755 nm) – Sometimes used in resistant cases.

→ Photodynamic therapy (PDT) – Experimental, combining light with photosensitizers.

→ Surgery or cryotherapy – Rarely used due to poor cosmetic outcomes and scarring risk.

Despite alternatives, PDL remains the safest and most effective long-term solution, especially in Korea where advanced systems are available.

Preparation

Proper preparation ensures safe and effective treatment.

➤ Dermatologic evaluation – A full clinical exam confirms diagnosis and rules out associated syndromes.

➤ Photography – High-quality images are taken to track results over time.

➤ Sun protection – Patients must avoid tanning, as darker skin absorbs more laser energy.

➤ Anesthesia –

• For small lesions, topical numbing cream may suffice.
• For large areas or children, sedation or general anesthesia may be used.

➤ Parental counseling (in pediatric cases) – Families are informed about the staged nature of treatment and expected outcomes.

How it’s done

Staged pulsed-dye laser therapy follows a structured process.

➔ Protective measures – Goggles or shields are used for both patient and staff.

➔ Laser application –

• The PDL handpiece delivers short bursts of yellow light.
• The energy is absorbed by blood vessels, causing them to collapse.
• Cooling devices or cryogen sprays protect the skin surface.

➔ Treatment session – Each session lasts 15–45 minutes, depending on lesion size.

➔ Number of sessions – Multiple treatments are required, spaced 4–8 weeks apart, with progressive lightening over time.

Recovery

Recovery from PDL treatment is usually simple.

→ The treated area develops temporary bruising (purpura), lasting 1–2 weeks.

→ Mild swelling or redness may occur but resolves quickly.

→ Patients are advised to keep the skin clean, moisturized, and sun-protected.

→ Makeup can be applied after a few days to cover bruising.

→ Children and adults typically resume daily activities immediately.

→ Results improve gradually with each session; some lesions fade 50–90%, though complete clearance is rare.

Complications

While safe, PDL treatment has possible side effects.

✔ Temporary purpura (bruising) – Expected and part of the healing process.

✔ Redness and swelling – Short-term and mild.

✔ Pigmentation changes – Hypopigmentation or hyperpigmentation may occur, especially in darker skin tones.

✔ Blistering or crusting – Rare, heals with proper care.

✔ Incomplete clearance – Older or thicker stains may be resistant.

✔ Recurrence – Vessels may dilate again over time, requiring maintenance therapy.

Serious complications such as scarring are very rare in Korea due to advanced technology and expertise.
