Does pulsed dye laser treatment treat spider veins?

Spider veins are small visible blood vessels near the skin surface. Pulsed dye laser light is absorbed by blood within selected vessels, creating heat that can make them fade as the skin heals. It is generally more useful for fine red vessels than for larger blue veins or veins that bulge. Some vessels may need more than one appointment, and new vessels can appear later because the treatment does not change every factor that contributes to them. Bruising, swelling, temporary colour change, or tenderness can follow treatment.

Have the area examined before booking a laser session. A clinician may distinguish spider veins from varicose veins, a vascular birthmark, or another skin change. Tell them about previous clotting problems, circulation symptoms, medicines, tanning, and a history of dark marks after skin injury. Ask whether laser, another procedure, or observation fits the vessel size and location. Follow instructions about shaving, skincare, cooling, dressings, and sun protection after treatment.

Arrange medical assessment promptly if a new vein is painful, warm, hard, rapidly enlarging, or surrounded by marked swelling. Seek urgent help for sudden one-sided leg swelling, chest pain, or breathlessness. After laser treatment, contact the clinic for severe pain, blistering, skin breakdown, spreading redness, or signs of infection such as worsening warmth and discharge.

Ask whether the vessels are suitable for pulsed dye laser, what colour change or fading is realistic, and whether another treatment is more appropriate for larger veins. Discuss the chance of temporary bruising or pigment change, preparation for your skin tone, aftercare, and what symptoms would need review.
