Keloids are stubborn, collagen-rich scars, so control usually needs a combined plan (steroid injections, pulsed dye laser, silicone) over 3 or more visits rather than a single procedure.
Keloid treatment in Gangnam, Seoul typically combines intralesional steroid injections to soften the scar, pulsed dye laser to reduce redness and thickness, and silicone support to lower recurrence. Because keloids are prone to coming back, care runs over a series of visits. At our Gangnam (Seoul) location, Dr. Yoongon Ryu builds the plan in English.

A keloid is a raised, firm scar that grows beyond the boundary of the original wound, unlike a normal scar that stays within it. Keloids form when the skin over-produces type I and III collagen during healing, driven by overactive fibroblasts and the TGF-beta pathway. They are more common in people with darker or Asian skin, with the incidence in people of African descent reported at roughly 5 to 15% versus under 1% in lighter skin, and they often appear on the chest, shoulders, earlobes, and jawline. Crucially, keloids are known to recur, so treatment aims to flatten, soften, and control them rather than promise a one-time cure.
Because no single tool reliably controls a keloid, modern care in Seoul is combination-based. Intralesional corticosteroid injections, usually triamcinolone, remain first-line: they soften the scar and reduce itch and redness over a series of sessions. Pulsed dye laser (PDL) targets the blood vessels that feed the scar, easing redness and thickness. Silicone gel or sheeting supports the healing surface and helps lower recurrence. For firmer or resistant keloids, doctors may add 5-fluorouracil to steroid injections to improve response.
At Reberry Clinic, keloid care is consultation-led and delivered in English. At our Gangnam (Seoul) location, Dr. Yoongon Ryu assesses the keloid’s size, age, and location, then sequences steroid injections, laser, and silicone support into a realistic, multi-visit plan. Gangnam is easily reached (Seocho, about 2 minutes from Gangnam Station exit 10), and international patients are supported across our three Seoul-area locations.
Keloid control works best when several mechanisms are combined, because a keloid is both an overgrown collagen mass and an over-vascularised, inflamed scar. Intralesional triamcinolone is injected directly into the scar to suppress the overactive fibroblasts and excess collagen, flattening the keloid and easing itch over roughly 3 to 4 sessions spaced about 4 weeks apart. Pulsed dye laser delivers 585 to 595nm light that is absorbed by the scar’s blood vessels, reducing the redness and thickness that feed keloid growth; studies of PDL combined with steroid report better flattening than steroid alone. Silicone gel or sheeting, applied daily over weeks, hydrates and occludes the scar surface and is supported as a first-line adjunct for lowering recurrence. For thick or resistant keloids, adding 5-fluorouracil to the steroid injection can improve softening and reduce relapse. Because keloids commonly recur, the doctor sequences these tools, monitors response, and continues maintenance rather than treating once and stopping.

The doctor grades size, age, location, and symptoms, since a 6-month earlobe keloid differs from a years-old chest keloid.
Intralesional triamcinolone is injected over about 3 to 4 sessions spaced roughly 4 weeks apart to flatten and soften the scar.
PDL at 585 to 595nm targets the scar’s blood vessels across several sessions to reduce redness and thickness.
Daily silicone gel or sheeting over weeks helps flatten the scar surface and lowers the chance of recurrence.
For firm or relapsing keloids, 5-fluorouracil may be combined with steroid, since combination therapy reports recurrence near 17% versus higher rates for single agents.

At our Gangnam (Seoul) location, Dr. Yoongon Ryu assesses the keloid’s size, age, and location, then explains a realistic combined plan in English.
A steroid injection session usually takes about 15 to 20 minutes, and laser can be layered in during the same course.
Keloid care runs as a series, typically 3 to 4 injection sessions about 4 weeks apart, plus daily silicone support at home.
Flattening and reduced itch build over several sessions across months, and your doctor reviews progress to adjust the plan.
Because keloids can recur, maintenance reviews and continued silicone use help hold results rather than treating once and stopping.
Keloids in Gangnam are usually treated with a combined plan: intralesional steroid injections to soften the scar, pulsed dye laser to reduce redness and thickness, and silicone support to lower recurrence. Because keloids recur, care runs over several visits. You can see the broader approach on our laser treatment page.
A keloid is a raised, firm scar that grows beyond the edges of the original wound, unlike a normal scar that stays within it. It forms when skin over-produces type I and III collagen during healing. Keloids commonly appear on the earlobe, chest, shoulder, and jawline, and are more frequent in darker and Asian skin.
Keloids are managed and controlled rather than cured in one visit, because they are prone to recurrence even after good flattening. A combined plan lowers the risk of return, but honest clinics do not promise a permanent one-time fix. Ongoing silicone support and maintenance reviews help keep the scar flat and comfortable over time.
Intralesional steroid injections cause a brief stinging or pressure sensation as the medication enters the firm scar, which most patients tolerate well over the short session. Techniques and a fine needle help manage comfort. Your doctor explains each step, and you can review related options on our laser treatment page.
Downtime is minimal for most keloid modalities. Steroid injections may leave brief soreness at the site, pulsed dye laser can cause temporary redness or light bruising for a few days, and silicone is painless. You can return to normal activity quickly, and your doctor advises on any short-term care between sessions.
Most keloid plans use about 3 to 4 steroid injection sessions spaced roughly 4 weeks apart, often with laser layered in and daily silicone at home. The exact number depends on the keloid’s size, age, and how it responds. Your doctor reviews progress between visits and adjusts the plan accordingly.
Combined treatment aims to flatten and soften the keloid substantially, though the degree varies by scar and skin type. Injections reduce bulk, laser eases redness, and silicone supports the surface. Results build across sessions rather than instantly, and your doctor sets realistic expectations about how flat a particular keloid is likely to become.
Yes, pulsed dye laser targets the blood vessels feeding the scar, reducing redness and helping flatten thickness, and studies show it improves results with steroid injections. Explore related laser treatment options with your doctor, who decides how many sessions suit your keloid at consultation.
Keloids relate to how fibroblasts and collagen behave during healing, and this tendency is stronger in darker and Asian skin, with reported incidence of about 5 to 15% in people of African descent versus under 1% in lighter skin. This is why doctors tailor injection strength and laser settings carefully for each skin type to balance results and safety.
Yes, 5-fluorouracil is sometimes combined with steroid for firm or resistant keloids, and studies report recurrence around 17% for the combination at nearly 2 years, better than many single-agent results. Whether it is added depends on how your keloid responds. Your doctor explains this option and its role within your overall plan.
Most adults with a diagnosed keloid on the earlobe, chest, shoulder, or jawline suit a combined plan, and skin-supportive options like Rejuran Healer may aid recovery. A consultation grades the scar; if you are pregnant or on certain medications, your doctor adapts the approach to keep it safe.
Keloid treatment is a well-established dermatological process and is generally considered safe when a trained doctor tailors injection strength and laser settings to your scar and skin type. A consultation reduces risks like skin thinning from over-injection. You can review the approach on our laser treatment page first.
Daily silicone gel or sheeting, sun protection, and avoiding tension or trauma on the scar all help reduce recurrence between sessions. Consistency matters because keloids can regrow. A supportive skin care routine keeps the area healthy, and your doctor schedules reviews so any early return is treated promptly.
Our Gangnam (Seoul) location is in Seocho, about 2 minutes from Gangnam Station exit 10, where Dr. Yoongon Ryu provides keloid care in English. International patients are also supported across our other Seoul-area locations, so you can choose the branch that best fits your stay. Directions are confirmed at booking.
Because keloid care runs as a series, many international patients begin a course in Seoul during 2 to 3 days for the first injection and consultation, then continue on return visits or with remote guidance. Our English-speaking team helps plan session timing around your travel so the plan stays on track.
Yes, flying within a day or so is generally fine after steroid injections or pulsed dye laser, which are minor procedures. Any redness or soreness settles quickly. Continue your silicone support and sun protection while travelling, and your doctor arranges follow-up so the next session and progress review stay coordinated from abroad.
