Reticular veins are the bluish 1 to 3 mm feeder veins beneath the skin; a long-pulsed 1064-nm Nd:YAG laser can close many of them over a short series, while larger veins are referred for sclerotherapy assessment.
Reticular vein treatment in Seoul, Korea typically uses a long-pulsed 1064-nm Nd:YAG vascular laser that heats and closes the bluish feeder veins so the body reabsorbs them over weeks. Smaller veins respond well; larger feeder veins are referred for sclerotherapy assessment. At Reberry Clinic, the clinic’s doctors map your veins first, then plan a short series in English.

Reticular veins are the flat, bluish or greenish veins that sit just beneath the skin, most often on the legs, typically 1 to 3 mm wide. They are larger than the fine red spider veins (telangiectasias) on the surface but smaller than bulging varicose veins, and they frequently act as feeder veins that supply the tiny surface spider veins. Because of that feeder role, treating the reticular vein can improve both the visible vein and the spider veins it feeds.
The core in-clinic treatment is a long-pulsed 1064-nm Nd:YAG vascular laser. This wavelength passes through the upper skin and is absorbed by the oxygenated and deoxygenated blood inside the vein, heating the vessel wall so it seals and is gradually reabsorbed. It is well suited to smaller reticular veins and to patients who prefer a needle-free approach. Larger, more prominent feeder veins, or veins linked to underlying venous reflux, are not ideal for laser alone and are referred for sclerotherapy assessment, where a sclerosant solution is injected to collapse the vein.
At Reberry Clinic, care is consultation-led. The clinic’s doctors examine and map your veins, decide whether laser, a sclerotherapy referral, or a combination fits, and explain the plan in English. International patients are supported in Seoul, Korea across our operating locations, so treatment can be timed around travel.
The long-pulsed 1064-nm Nd:YAG laser targets haemoglobin, the pigment inside blood, rather than the skin’s surface. Because 1064 nm is a deeply penetrating wavelength, it reaches reticular veins sitting a few millimetres below the surface while the epidermis is spared, and contact cooling protects the skin during each pulse. The laser delivers energy in relatively long pulses, often in the tens of milliseconds, which heats the full diameter of a 1 to 3 mm vein evenly so the vessel wall is damaged and the vein seals shut. Over the following weeks the sealed vein is broken down and reabsorbed by the body, so the visible line fades gradually rather than disappearing instantly. Larger vessels tend to respond to more energy than very fine ones, which is why the doctor selects fluence and pulse duration to match each vein’s calibre. When a reticular vein is too large, tortuous, or connected to deeper venous reflux, laser alone is less effective and the vein is referred for sclerotherapy, where an injected sclerosant collapses the vessel from within. This is why vein mapping at consultation matters: it decides which tool suits which vein.

The clinic’s doctors assess each vein and separate the 1 to 3 mm reticular veins suited to laser from larger veins that need sclerotherapy assessment.
For laser, fluence and a pulse duration in the tens of milliseconds are matched to each vein’s calibre, since larger veins need more energy than fine ones.
The 1064-nm Nd:YAG laser is passed along the vein with contact cooling; a session usually takes about 15 to 30 minutes depending on how many veins are treated.
The sealed vein fades over 4 to 8 weeks as the body reabsorbs it, so results appear gradually rather than immediately after 1 session.
At the follow-up, usually about 4 to 6 weeks later, the doctor checks the response; veins that need more or are too large are referred for sclerotherapy or a further session.
See representative outcomes from Reberry Clinic. Results build gradually and vary by individual; your plan is assessed at consultation.
The clinic’s doctors map and measure your veins, decide between laser and a sclerotherapy referral, and explain the plan and expected sessions in English.
A laser session usually takes about 15 to 30 minutes depending on how many veins are treated, with contact cooling for comfort.
Many reticular veins need 1 to 3 sessions spaced several weeks apart, so treatment is planned as a short course rather than one visit.
Treated veins fade over roughly 4 to 8 weeks as the body reabsorbs the sealed vessel, and your doctor reviews the response at follow-up.
Closed veins usually do not return, but new veins can form over years, so occasional review and sun protection of treated skin are advised.
Reticular vein treatment usually means a long-pulsed 1064-nm Nd:YAG vascular laser that heats and seals the bluish 1 to 3 mm feeder veins so the body reabsorbs them. Larger veins are referred for sclerotherapy. A consultation maps your veins first, which you can begin via our laser treatment page.
Reticular veins are the flat, bluish feeder veins about 1 to 3 mm wide sitting beneath the skin, while spider veins are the fine red surface lines they often supply. Because reticular veins feed spider veins, treating the feeder can improve both. Your doctor identifies each type when mapping your veins at consultation.
Most patients feel a brief warm snapping sensation with each pulse, eased by contact cooling on the skin, and the treatment is needle-free. Comfort is generally good and sessions are short. If your veins are larger and need sclerotherapy instead, that involves minor needle sticks that are also usually well tolerated.
Many reticular veins clear over 1 to 3 laser sessions spaced several weeks apart, since the vein fades gradually as it is reabsorbed. Larger or stubborn veins may need more sessions or a sclerotherapy referral. Your doctor confirms the likely number after mapping your veins and seeing how they respond.
Treated reticular veins fade over roughly 4 to 8 weeks as the sealed vessel is reabsorbed, not immediately after the session. Larger veins take longer than fine ones. Your doctor reviews the result at follow-up and decides whether a repeat pass or a sclerotherapy referral will improve remaining veins.
Larger reticular veins, tortuous veins, or veins linked to deeper venous reflux respond better to sclerotherapy, where an injected solution collapses the vein. Laser suits smaller feeder veins. Your doctor decides during vein mapping, and you can read about related energy-based options on our laser treatment page.
Laser vein treatment usually has little to no downtime, so most patients resume normal activity the same day. Mild redness, warmth, or temporary bruising over the vein can occur and settles within days. A gentle skin care routine keeps the treated area comfortable while it heals.
A successfully sealed vein usually does not return, but the tendency to form veins remains, so new reticular or spider veins can appear over years. Treatment addresses existing veins, not the underlying tendency. Occasional review helps catch new veins early, and your doctor discusses realistic expectations at consultation.
Yes, laser is often combined with a sclerotherapy referral for mixed vein sizes, treating small feeder veins with laser and larger ones by injection. Surface spider veins may also be addressed. Your doctor sequences a combined plan so each vein is treated with the most suitable tool for its size.
Adults with smaller 1 to 3 mm bluish reticular veins who prefer a needle-free option are typically good candidates. Larger varicose veins or suspected venous reflux are assessed first, as these may need vascular referral. A consultation maps your veins and confirms whether laser, sclerotherapy, or both fit your case.
The 1064-nm wavelength is comparatively skin-safe because it targets blood rather than surface pigment, and contact cooling protects the epidermis. If any temporary marks appear, our dark spot removal approach can address them. Your doctor adjusts settings for your skin tone to treat the vein safely.
Aftercare is usually simple: protect the treated area from strong sun, avoid vigorous heat exposure for a short period, and follow any support-wear advice if given. Gentle skincare helps the skin recover. A supportive skin care routine keeps treated skin comfortable while the vein reabsorbs over the following weeks.
Often yes, because reticular veins frequently feed the surface spider veins, so sealing the feeder can reduce the pressure that maintains the spider veins. Some spider veins still need direct treatment afterwards. Your doctor plans the sequence during vein mapping so the underlying feeder is addressed before treating surface lines.
For a first session, 2 to 3 days is comfortable, allowing vein mapping, the procedure, and a short review. Because some veins need repeat sessions, many international patients begin in Seoul and return for follow-ups. Our English-speaking team helps coordinate timing around your travel plans and any support advice.
Yes, flying within a day or so is generally fine after laser vein treatment, which is non-invasive. Because long-haul flights involve prolonged sitting, staying hydrated and moving your legs during the flight is sensible. If you have any support-wear advice, your doctor will explain how to manage it while you travel.
International patients can complete vein treatment across one or more visits, and the clinic offers remote check-ins in English between trips so the plan stays on track. You can continue gentle skin care at home. Your vein map and treatment notes are kept on file for continuity across sessions.
