Keloid injections deliver a corticosteroid, commonly triamcinolone, directly into the scar. The steroid reduces inflammation and slows the excess collagen production that makes keloids grow, so the scar gradually flattens and softens. At Re:berry Hongdae these injections are typically repeated every four to six weeks over several sessions, depending on the scar.

What is a keloid?
A keloid is a raised scar that grows beyond the boundaries of the original wound. It forms when the body produces too much collagen during healing. Keloids are more common on the earlobes, chest, shoulders and jaw, and after piercings, acne or surgery. They can itch, feel tender and continue to enlarge over time. Genetics and skin type play a role.
How does the injection flatten a keloid?
Corticosteroids work in three main ways when injected into scar tissue:
- Reducing inflammation: calming the activity that drives scar growth.
- Slowing collagen production: reducing the overactive fibroblasts that build the scar.
- Breaking down existing collagen: helping the scar soften and shrink over time.
Many patients notice less itching and tenderness first, followed by gradual flattening across several sessions. More on our Keloid and Scar Injection page.
How many injections are needed?
The number depends on the keloid's size, age and location. Small, recent keloids may respond within a few sessions, while larger or older ones may need more. Spacing of around four to six weeks allows the doctor to assess response and adjust the dose. See how many keloid injections are needed.
Who should not have steroid injections?
Tell the doctor if you are pregnant or breastfeeding, have diabetes, an infection near the scar or a history of reacting to steroids. These do not always rule out treatment, but they change how it is planned. Very large keloids may need combined treatment rather than injection alone.
What are the side effects?
Possible effects include temporary pain at injection, skin thinning or a slight dent, lighter skin color around the scar and small visible blood vessels. Careful dosing reduces these risks. Keloids can recur, so combination approaches, such as laser or pressure therapy, may be discussed. Pricing depends on scar size and plan and is confirmed in writing at consultation.

Related questions
Do keloid injections hurt?
Keloid tissue is dense, so injections can be uncomfortable, especially on sensitive areas like earlobes or the chest. The procedure is quick, often a few minutes. Numbing options may be offered. Many patients find that discomfort decreases in later sessions as the scar softens.
Can keloids come back after injections?
Yes, keloids can recur, particularly after trauma to the area or in people prone to them. Continuing follow-up, avoiding new piercings or injury nearby and using combination treatment when advised can help. Your doctor will discuss a plan to reduce the chance of recurrence.
Can I get keloid injections while traveling?
A single session is possible during a visit, but keloids usually need several injections spaced four to six weeks apart. Travelers may start treatment in Seoul and continue with a qualified local doctor. Keep a record of the medication and dose so your next provider can follow up safely.
