Long-pulsed 1064 nm Nd:YAG laser targets vessels up to about 3 mm wide, sparing surface skin so most patients need only 1 to 3 sessions.
Spider vein treatment is safe in Korea when a trained doctor uses a long-pulsed 1064 nm Nd:YAG laser matched to your skin tone and vessel size. The laser heats the vein while sparing the surface, so most patients need 1 to 3 sessions with little downtime. A consultation and conservative settings reduce risks such as bruising or temporary pigment change.

Spider veins (telangiectasias) are fine red, purple, or blue vessels visible near the surface of the skin, common on the face and legs. Laser spider vein treatment uses a long-pulsed 1064 nm Nd:YAG laser to deliver heat that is absorbed by the blood inside the vessel, coagulating it so the body gradually clears it. The overlying skin is spared, which is why lasers can treat vessels without cutting or injecting.
Because the treatment heats blood vessels, safety questions centre on bruising, temporary pigment change, and, rarely, small blisters if energy is too high. The 1064 nm wavelength is chosen partly for safety in darker skin, since it passes the epidermal melanin more readily than shorter wavelengths and reaches deeper vessels. Correct settings and cooling are what keep these risks low.
At Reberry Clinic, spider vein treatment is consultation-led: the clinic’s doctors assess vessel size, location, and your skin tone before choosing energy and pulse settings. International patients are supported in English in Korea, so screening, realistic expectations, and aftercare are explained clearly before anything is done.
The long-pulsed 1064 nm Nd:YAG wavelength is absorbed by haemoglobin in the vessel while passing through surface skin with relatively little melanin absorption, which is why it suits Fitzpatrick types III to V better than shorter vascular wavelengths. Heat coagulates the vessel wall so the body reabsorbs it over weeks. The doctor sets fluence (energy), pulse duration (matched to vessel diameter, longer for larger vessels), and spot size, while contact or air cooling protects the epidermis and reduces discomfort. Conservative settings on darker skin limit post-inflammatory pigmentation, and careful energy control keeps bruising and rare blistering uncommon. The biggest safety variable is the operator selecting settings appropriate to the vessel and skin tone, not the device alone, and confirming the veins are cosmetic surface vessels rather than a sign of underlying venous disease.

A consultation reviews vessel size, location, skin tone, and history to confirm the veins are cosmetic before any of the 1 or more passes.
The 1064 nm beam passes surface melanin, making it a safer choice for Fitzpatrick types III to V than shorter vascular wavelengths.
Energy and pulse duration are set to the vessel, using longer pulses for larger veins up to about 3 mm to heat them evenly.
Contact or air cooling protects the surface during each of the pulses, which lowers discomfort and the small risk of blistering across the 1 to 3 session course.
Sun protection and gentle care over the following weeks help minor bruising fade and keep pigment change unlikely.
See representative outcomes from Reberry Clinic. Results build gradually and vary by individual; your plan is assessed at consultation.
The clinic’s doctors examine vessel size, location, and skin tone, confirm the veins are cosmetic, screen for contraindications, and explain risks in English.
After cleansing and optional numbing, treating a small area usually takes 15 to 30 minutes with cooling applied during each pulse.
You may feel a brief snap with each pulse; mild redness and occasional light bruising settle over the first few days.
Treated vessels darken then fade as the body clears them, usually over 2 to 6 weeks, often across 1 to 3 sessions.
Treated veins are cleared, but new vessels can form over time; sun protection and gentle care keep pigment change unlikely.

The laser heats the vein while sparing the surface, so most patients need only 1 to 3 sessions. A consultation and conservative settings keep risks like bruising low.
The most common effects are temporary redness, mild swelling, and occasional light bruising that fade within days. Post-inflammatory pigment change is possible, mainly in darker skin, and small blisters are rare with correct energy. Proper screening and settings, explained on our laser treatment page, keep these risks low.
Spider vein treatment can be safe for Asian and darker skin because the 1064 nm Nd:YAG wavelength passes surface melanin to reach vessels, lowering the risk of pigment change. Skin tone assessment at consultation guides conservative settings, and strict sun protection afterwards is important. Reports in Fitzpatrick types III to IV note little lasting pigment change with careful energy.
The 1064 nm Nd:YAG laser delivers heat that is absorbed by blood inside the vessel, coagulating the vein wall so the body gradually reabsorbs it over 2 to 6 weeks. The surface skin is spared, which is why no cutting is needed. You can compare vascular options on our laser treatment page.
Healthy adults with cosmetic surface spider veins on the face or legs are usually good candidates. A consultation confirms the veins are not a sign of underlying venous disease and rules out contraindications. Darker skin tones are treatable with conservative settings, so a doctor’s assessment ensures the treatment is both safe and suitable for you.
Most patients feel a brief snap or heat with each pulse, often compared to a rubber band, eased by surface cooling and sometimes numbing cream. Legs can be slightly more sensitive than the face. Afterwards the area may feel warm for a short time, similar to mild sunburn, which settles over the first day.
Downtime is minimal: expect brief redness and sometimes light bruising that fades over a few days to about two weeks. You can usually return to normal activities immediately, avoiding intense heat, hot baths, and strenuous exercise for a day or two. Sun protection helps the treated area heal without pigment change.
Treated vessels often darken first, then fade as the body clears them over about 2 to 6 weeks. Fine veins can respond after a single session, while denser or larger vessels usually improve across 1 to 3 sessions. Your doctor sets realistic expectations, since not every vessel clears fully at the same rate.
Most cosmetic spider veins are addressed in 1 to 3 sessions spaced several weeks apart, allowing each treated vessel to clear before the next pass. More extensive areas may need additional sessions. Your doctor confirms a safe schedule at consultation. You can compare options on our laser treatment page.
A vessel that is properly treated is cleared and does not typically return, but the tendency to form spider veins remains, so new ones can appear over time due to genetics, sun, or hormones. These new vessels can be treated the same way. Sun protection and skin care help slow new vessel formation.
Yes, spider vein treatment can be staged with other facial or skin care, though not always on the same spot on the same day. Once any redness settles, a supportive skin care routine can continue. Your doctor sequences treatments so each treated area recovers fully between sessions.
Expect brief redness, mild swelling, and possibly light bruising over the treated vessels for a few days. Temporary darkening along the vein path is common as it clears, then fades. Less commonly, transient pigment change or, rarely, a small blister can occur; cooling and correct energy markedly lower these risks for most patients.
Avoid intense heat, hot baths, and vigorous exercise for a day or two, apply any prescribed soothing product, and use daily sunscreen with sun avoidance early on. A gentle skin care routine supports healing. Your doctor gives written aftercare suited to your skin tone and the vessels treated.
No, recent significant sun exposure or a fresh tan raises the risk of burns and pigment change, so treatment is usually postponed. Doctors prefer skin that is not sun-stressed before vascular laser work. Planning your trip so treated skin avoids heavy sun before and after the session keeps spider vein treatment safer for your skin.
Staying about 3 to 5 days lets you have a consultation, a session, and an early review while any bruising is minor. If you want to space multiple sessions, a longer stay or split trip can be arranged, since sessions are weeks apart. Our English-speaking team helps coordinate timing around your travel.
Yes, flying within a day or two is generally fine, as laser spider vein treatment is non-surgical with minimal downtime. If your legs were treated, moving during the flight and staying hydrated is sensible. Keep skin protected from sun at your destination, and your doctor will confirm timing based on the area treated.
International patients can complete a spider vein plan over one or more visits, and the clinic offers remote check-ins in English between trips to review how vessels are clearing. You can also arrange related care such as ongoing skin care when you return, with your treatment notes kept on file.
