Most patients need 2 to 4 Nd:YAG laser sessions spaced 6 to 8 weeks apart, while stubborn leg veins can need more.
Most people need 2 to 4 Nd:YAG laser sessions for spider veins in Korea, spaced about 6 to 8 weeks apart, while larger or deeper leg veins often need the higher end or more. The exact count depends on vessel size, location, skin tone, and how well each vein responds, so the clinic’s doctors confirm your plan at consultation.

For most facial and fine spider veins, Nd:YAG laser treatment in Korea is planned as a short course of 2 to 4 sessions spaced roughly 6 to 8 weeks apart, allowing each treated vessel to fully clear before the next visit. Small facial telangiectasias sometimes respond in one or two sessions, while leg veins, which are larger and deeper, generally need more because they clear more gradually.
Spider vein treatment is progressive rather than instant: the laser heats and collapses targeted vessels, and the body then reabsorbs them over the following weeks, so a spaced series lets each round settle before treating what remains. The 6 to 8 week gap also lets any temporary bruising or pigment fade before the next session. The clinic’s doctors review each area after treatment and adjust settings and the number of remaining sessions accordingly.
At Reberry Clinic, the session count is consultation-led rather than a fixed package, because vessel size, depth, and skin tone strongly affect how many passes are worthwhile and how conservatively the laser must be set. International patients are supported in English across three Seoul-area locations (Gangnam, Myeongdong, Incheon Airport), so a plan can be paced around return trips if needed.
The long-pulsed 1064 nm Nd:YAG laser targets oxygenated haemoglobin inside the vessel, heating the blood and vessel wall so the spider vein collapses and is gradually reabsorbed. Its longer wavelength reaches deeper vessels than shorter-wavelength devices, which is why it is often chosen for both facial and leg telangiectasias. Because each pass treats the vessels visible and reachable that day, and the body clears them over weeks, more than one session is usually needed to reach the vessels that remain.
Deeper, wider, or clustered leg veins clear more slowly, so treatment is spaced 6 to 8 weeks apart to let each round resolve and any bruising fade before the next. Reberry Clinic is a dermatology clinic where this vascular laser work is performed by the clinic’s doctors, who use conservative settings in darker tones to limit pigment change and explain when a different approach on the laser treatment page may need a different session plan.

The clinic’s doctors examine vessel size, depth, and skin tone to estimate whether 2, 3, or 4+ sessions fit your goals.
A conservative first pass treats the visible vessels, setting a baseline for how well they collapse and clear.
You wait about 6 to 8 weeks so treated veins are reabsorbed and any bruising fades before the next session.
Your doctor reviews clearance and refines settings for the next 1 or 2 sessions, targeting the vessels that remain.
Most facial plans finish within 2 to 4 sessions, while leg veins may run further before maintenance.

After brief preparation, a session usually takes about 15 to 30 minutes depending on the area treated.
Expect a quick snapping or warm sensation as each vessel is treated, with possible temporary redness or bruising after.
Treated veins clear over the weeks after each session, with fuller results building across the planned course.
Sun protection and any advised compression help; your doctor decides if further sessions are worthwhile after reviewing clearance.

Each pass treats the vessels reachable that day, and the body then reabsorbs them over the following weeks, so a single session rarely reaches everything. Spacing sessions 6 to 8 weeks apart lets treated veins clear and bruising fade before the next round. This is why a short course, not one pass, gives fuller clearance.
Sessions are usually spaced about 6 to 8 weeks apart so treated vessels are reabsorbed and any bruising or pigment fades before the next pass. Shorter gaps offer little benefit and can raise irritation. Your doctor confirms timing based on how your veins respond, reviewing progress with options on our laser treatment page.
Yes, leg spider veins are larger and deeper, so they clear more slowly and generally need 4 or more sessions, while fine facial telangiectasias may respond in 2 to 3. Vessel depth strongly drives the count, and your doctor examines each area on our laser treatment page to set a realistic number of sessions.
Usually no, because sessions need 6 to 8 weeks between them for veins to clear, so a full course rarely fits one short visit. Many international patients have one session per trip or pace a plan across return visits. Our English-speaking team helps schedule sessions around your travel so each area settles properly.
Yes, darker skin tones use gentler, more conservative laser settings to limit pigment change, which can mean an extra session to reach the same clearance. This trade-off favours safety over one aggressive pass. Your doctor matches the settings to your tone, so the session count reflects safe parameters for your skin.
Usually mild, with possible temporary redness, mild swelling, or small bruises for a few days after each session, and occasionally brief pigment change. Most patients return to normal activity quickly. Because this can repeat with each session, plan any social timing around the short recovery window when scheduling a multi-session course.
Treated veins fade over the weeks following each session as the body reabsorbs them, rather than disappearing instantly, so improvement builds gradually. This is why sessions are spaced and why leg veins improve across the course. Your doctor reviews clearance before deciding on the settings and timing of the next session.
Once treated, an individual spider vein that has fully cleared does not typically return, so results from a completed course can last a long time. However, new spider veins can form over the years due to genetics, sun, and other factors, so occasional maintenance sessions, rather than a full repeat course, are sometimes helpful.
Yes, laser vein work is often part of a wider plan and is spaced from other facial treatments to avoid over-stressing skin. A gentle hydrating facial can suit non-treated areas between sessions. Your doctor sequences treatments so each area heals properly while you complete a multi-session vein course.
For deeper or more defined vessels, the long-pulsed 1064 nm Nd:YAG laser reaches deeper than IPL, which suits diffuse surface redness better, so they often serve different needs rather than one always winning. Your doctor recommends the approach and session count that fits your specific vessels and skin tone at consultation.
Between sessions, protect the area with strict sunscreen, avoid heat and vigorous activity right after treatment, and follow any compression advice for leg veins. A gentle supportive routine, such as our skin care options, aids recovery, and your doctor provides a written plan to follow before the next session.
Not always; clearance accumulates across a planned course but plateaus once the reachable vessels are treated, so extra sessions beyond what your veins need add little while raising irritation risk. Your doctor judges when results have peaked and recommends stopping or spacing maintenance. The aim is the right number of sessions, not the most.
Often just 1 to 2 days per session is enough, since downtime is usually mild and veins clear at home over the following weeks. Staying a little longer lets you have a consultation and one session comfortably. Our English-speaking team helps plan each session around your trip dates.
International patients can complete a spider vein course across one or more visits, and the clinic offers remote check-ins in English to review clearance between sessions. You can also book gentler maintenance such as ongoing skin care on return trips. Your treatment notes are kept on file so each session continues the plan.
