Most people need 1 to 3 fine CO2 laser sessions to remove syringomas in Korea, spaced several weeks apart. Because syringomas sit deep in the dermis and are prone to returning, some cases need extra touch-ups over time. The number depends on lesion count, depth, and skin tone, confirmed at consultation.

For most people, syringoma removal in Korea is planned as a short course of 1 to 3 fine CO2 laser sessions spaced several weeks apart, because these small benign sweat-duct growths sit within the dermis and are treated by carefully vaporising them in controlled passes. Discrete, shallower papules often clear within one or two sessions, while plaque-type or mixed clusters usually need the full range or more.
Syringomas are known to be recurrence-prone: because the lesions are embedded in the dermis, complete removal is difficult and some can return months or years later, which is why touch-up sessions are sometimes needed even after a good initial result. The spacing between sessions matters because the treated skin must heal fully before the next pass, and treating too aggressively in one sitting raises the risk of scarring or pigment change, especially around the delicate under-eye area.
At Reberry Clinic, the session count is consultation-led rather than a fixed package, because lesion depth, number, and skin tone strongly affect 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 and any touch-ups can be paced around return trips.
Syringomas are small benign tumours of the eccrine sweat ducts that sit within the dermis, most often clustered under and around the eyes. Fine CO2 laser removes them by emitting light at a 10,600 nm wavelength absorbed by water in the tissue, vaporising the lesion in controlled micro-passes; because they are deep-seated, the doctor works cautiously layer by layer rather than ablating aggressively in one go. This conservative, staged approach is exactly why one gentle session is often not enough for clustered or deeper lesions, and why a short series is planned.
Around the thin skin of the eyelids, over-treating in a single session raises the risk of scarring, redness, and pigment change, particularly in darker tones. Reberry Clinic is a dermatology clinic where fine ablative laser work is performed by the clinic’s doctors, who set conservative parameters and explain how syringoma removal fits within the broader options on the laser treatment page.

The clinic’s doctors count and grade lesion depth and skin tone to estimate whether 1, 2, or 3 sessions fit your goals.
A conservative first pass vaporises the most treatable lesions in about 15 to 30 minutes, setting a baseline for how your skin heals.
You wait several weeks, often 4 or more, so the delicate treated skin recovers fully before any repeat session.
Your doctor reviews clearance after healing and treats remaining or deeper lesions in the next 1 or 2 sessions.
Most plans finish within 1 to 3 sessions, though occasional touch-ups may follow since syringomas can recur.

The clinic’s doctors count and assess your lesions and skin tone in English and estimate whether 1 to 3 sessions fit your goals.
After 30 to 60 minutes of numbing, the fine laser work usually takes 15 to 30 minutes depending on lesion count.
Expect a warm, prickling sensation during treatment and small crusts with redness for several days after each session.
Treated lesions settle over 2 to 4 weeks per session, with remaining lesions addressed in later sessions.
Strict sun protection and gentle care aid healing; because syringomas can recur, your doctor advises whether touch-ups may be useful later.



Most people need 1 to 3 fine CO2 laser sessions spaced several weeks apart, with clustered or deeper lesions sometimes needing more. Because syringomas are dermal and recurrence-prone, occasional touch-ups can follow. The clinic’s doctors confirm your plan after counting the lesions; you can review related options on our laser treatment page.
Syringomas sit deep in the dermis, so the doctor removes them conservatively layer by layer rather than ablating aggressively in one sitting, which would raise scarring risk. Clustered or deeper lesions therefore usually need 2 to 3 sessions spaced weeks apart for healing. A staged approach protects the delicate under-eye skin while clearing lesions safely.
Sessions are usually spaced several weeks apart so the treated skin heals fully before the next pass, especially around the thin eyelid area. Shorter gaps raise the risk of scarring and pigment change without benefit. Your doctor confirms timing based on how your skin heals, reviewing progress among our laser treatment options.
Yes, syringomas can recur because the lesions are embedded in the dermis and complete removal is difficult, so some return months or years later. Recurrence does not mean the treatment failed; it reflects the nature of the condition. Your doctor explains this at consultation and may suggest occasional touch-up sessions rather than a single definitive treatment.
Usually no, because sessions need several weeks between them for healing, 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 one heals properly.
Yes, darker skin tones use gentler, more conservative settings to limit post-inflammatory pigmentation, which can mean an extra session to reach the same clearance. This trade-off favours safety over one aggressive pass, especially near the eyes. Your doctor matches depth to your tone, so the session count reflects safe parameters for your skin.
Yes, each session leaves small crusts and redness at the treated points, usually settling over about 5 to 7 days as the skin renews. Around the eyes this can be visible, so plan social and travel timing around each recovery window. Your doctor gives gentle aftercare instructions to protect healing between sessions.
Treated lesions flatten as the crusts heal over 2 to 4 weeks, with the treated area looking clearer once redness fades. Remaining or deeper lesions are addressed in later sessions, which is why clearance builds across the course. Your doctor reviews progress before deciding on the next session, on our laser treatment page.
The under-eye area is the most common site and needs extra caution because the skin is thin, so the doctor works conservatively across sessions to protect it. This careful pacing can mean more sessions than a more forgiving area would need. Your doctor plans depth and density specifically for the delicate periorbital skin.
Both are ablative lasers used for syringomas; fine CO2 vaporises lesions with some collateral heat, while Er:YAG offers precise depth control with less residual heat. Neither eliminates recurrence, since lesions are dermal. Your doctor recommends the approach suited to your lesion type and skin tone from our laser treatment options.
Not always; benefit accumulates across a planned course but over-treating the delicate under-eye skin adds scarring and pigment risk without proportional gain. Because syringomas can recur regardless of session count, the goal is safe, meaningful clearance rather than the most sessions. Your doctor judges when to stop or plan a later touch-up instead.
Between sessions, keep the crusts clean and moisturised, avoid picking them, and use strict broad-spectrum sunscreen daily, since sun exposure raises pigment risk around the eyes. Gentle supportive care, such as our skin care options, aids healing, and your doctor provides a plan to follow before the next session.
Yes, syringoma removal can sit within a wider skin plan, though it is spaced from other resurfacing to allow the delicate area to heal. Some studies pair laser with adjuncts to reduce session numbers. Your doctor sequences any additional treatments so the eyelid skin is never over-stressed while you complete the course.
Because crusting is visible for several days, staying about 5 to 7 days lets you have a consultation, one session, and settle the initial redness before travelling. If your schedule is tight, your doctor can adjust how much is treated. Our English-speaking team helps plan each session around your trip dates.
International patients can complete removal across one or more visits, and the clinic offers remote check-ins in English to monitor healing and any recurrence between sessions. You can also book gentler care such as ongoing skin care on return trips. Your treatment notes are kept on file so each session continues the plan.
