Vascular Laser in Seoul: Treat Redness and Visible Vessels
The short answer
A vascular laser targets haemoglobin in blood vessels to shrink or close visible capillaries, reducing facial redness, rosacea, spider veins and red acne marks. In Gangnam a facial session typically costs about ₩100,000–₩400,000, takes 15–30 minutes, and leaves mild redness for a day, or bruising for about a week at stronger settings. Most people need 3–5 sessions spaced 3–6 weeks apart.
Key facts
- Treats: broken capillaries, rosacea, red acne marks, cherry angiomas, spider veins
- Common lasers: pulsed dye (V-Beam), long-pulsed Nd:YAG, KTP, Excel V
- Session time: 15–30 minutes
- Downtime: redness for 1 day; possible bruising for 5–7 days
- Sessions: typically 3–5, every 3–6 weeks
- Typical Seoul price: about ₩100,000–₩400,000 per facial session
How vascular lasers work
Vascular lasers emit wavelengths that are absorbed strongly by oxyhaemoglobin, the red pigment in blood. The light turns into heat inside the targeted vessel, damaging its wall so that it collapses and is gradually absorbed by the body. Surrounding skin is protected by cooling and carefully chosen pulse durations. Because the laser targets the vessel itself, it can treat redness that creams and skincare cannot reach.
Conditions a vascular laser can treat
- Broken capillaries (telangiectasia) on the nose and cheeks
- Background redness and flushing from rosacea
- Red marks left after acne (post-inflammatory erythema)
- Cherry angiomas and small spider angiomas
- Fine leg veins, usually with Nd:YAG
- Redness in new surgical scars

Laser options compared
| Laser | Wavelength | Best for | Bruising risk |
|---|---|---|---|
| Pulsed dye (V-Beam) | 595 nm | Diffuse redness, fine vessels, red marks | Higher at purpura settings |
| KTP | 532 nm | Small superficial vessels | Low |
| Long-pulsed Nd:YAG | 1064 nm | Deeper or bluish vessels, leg veins | Low |
| IPL | Broad spectrum | Redness with sun spots | Very low |
Some Gangnam clinics combine wavelengths in one platform to treat both fine red vessels and deeper blue ones in a single visit.
What happens during treatment
You wear protective eye shields while the doctor passes the handpiece over the area. Each pulse feels like a quick elastic snap, often with a burst of cold from the cooling system. Small vessels may visibly disappear or darken as they are treated. A facial session usually takes under half an hour, and numbing is rarely needed. Afterwards you may feel warmth like mild sunburn.
Downtime and aftercare
With non-purpuric settings, redness and mild swelling usually settle within 24 hours. If the doctor uses stronger purpuric settings for stubborn redness, grey-purple bruising can last five to seven days. For the first few days:
- Avoid hot showers, saunas, alcohol and strenuous exercise
- Use a gentle cleanser, moisturiser and mineral sunscreen
- Sleep with your head slightly raised if swelling appears
- Avoid exfoliants and retinoids for about a week
Results and maintenance
Treated vessels fade over one to two weeks. Larger single vessels may go in one or two sessions, while diffuse redness typically needs three to five. New vessels can still form over time, particularly with rosacea, sun exposure or alcohol, so many people book a maintenance session once or twice a year.
Is it safe for Asian and darker skin?
Yes, with appropriate settings. Melanin can also absorb some wavelengths, so careful parameter selection and test spots reduce the risk of pigmentation. Nd:YAG is often preferred for deeper skin tones. Our guide to Korean lasers for Asian skin explains how clinics adapt treatments.
Typical costs
Small spot treatments, such as a few cherry angiomas or a single vessel, can start around ₩50,000–₩100,000. Full-face sessions for diffuse redness usually cost ₩150,000–₩400,000 depending on the device and settings. Packages of three to five sessions are common and often include calming care. Leg veins are usually priced by area.
Planning treatment as a visitor
If you have a short stay, ask for non-bruising settings or schedule stronger sessions early so marks settle before you fly. Confirm which device will be used, whether a doctor performs the laser, and whether the price covers the full face or a single area. Bring photos of your redness on bad days to help the doctor plan.

Patient questions
Frequently asked questions
Will a vascular laser leave bruises?
At standard settings bruising is uncommon; stronger purpuric settings can cause bruising for about a week.
How many sessions do I need?
Single vessels may need 1–2 sessions, while diffuse redness typically needs 3–5.
Can broken capillaries come back?
Treated vessels do not return, but new ones can form, so occasional maintenance is common.
Does it hurt?
It feels like quick elastic snaps with cooling; most people tolerate it without numbing.
Can I wear makeup afterwards?
Usually from the next day, once any redness or swelling has settled.
