If a small cut, spot, piercing or surgical incision has left you with a raised, firm scar that keeps growing beyond the original wound, you may have a keloid. Keloids can itch, feel tender, catch on clothing and affect your confidence — and because they tend to grow rather than fade, they rarely improve fully on their own. The good news is that keloids respond well to the right treatment, especially when it is started early and matched to your skin and the scar’s location. In this guide, the specialist team at Precision Surgery in Birmingham explains what keloids are, why they form, and how the main treatment options compare, so you can approach your consultation with confidence.
Keloid or Hypertrophic Scar: Why the Difference Matters
Not every raised scar is a keloid, and the distinction genuinely changes your treatment. A hypertrophic scar stays within the boundaries of the original wound. It rises above the skin, can be red and itchy for a few months, but then gradually flattens and fades over one to two years without needing anything more than patience and good scar care.
A keloid behaves quite differently. It grows beyond the edges of the original injury, spilling into normal skin that was never damaged. Keloids keep growing for months or even years, they do not regress on their own, and they can appear after trivial injuries — a graze, an insect bite, an acne spot or an ear piercing. Some keloids appear spontaneously with no obvious injury at all. Keloids also have a strong tendency to come back after treatment, which is why a one-size-fits-all approach rarely works.
Getting this diagnosis right at your first appointment matters because hypertrophic scars and keloids respond differently to steroid injections, surgery and pressure therapy. A scar that is misdiagnosed as a keloid can be overtreated, while a true keloid that is treated as a simple raised scar often recurs.
Why Keloids Form — and Who Is Most at Risk
Keloids are the result of an overactive healing response. After the skin is injured, cells called fibroblasts produce collagen to close the wound. In people prone to keloids, this production does not switch off at the right time. Collagen keeps accumulating, the scar keeps expanding, and the resulting lump can become much larger than the injury that caused it.
Certain factors make keloids considerably more likely:
- Skin tone: Keloids are far more common in people with darker skin, including African, Caribbean and South Asian backgrounds, where they may be up to fifteen times more common than in people with fair skin.
- Age: Keloids most often develop between the ages of roughly 10 and 30, when wound healing is at its most active.
- Family history: A tendency to form keloids often runs in families, so if a parent or sibling has keloids, your own risk is higher.
- Body site: The chest, shoulders, upper back, jawline and ears are the classic keloid hotspots. Skin tension across the chest and shoulders is thought to be one reason these areas are so prone.
- Type of injury: Deep wounds that are slow to heal, burns, piercings and wounds that become infected all carry a higher keloid risk than clean, quickly healing cuts.
If you have formed a keloid before, it is worth telling your surgeon before any future procedure, because preventive steps taken at the time of surgery can dramatically reduce the chance of another one.
Keloid Treatment Options: How They Compare
There is no single “best” keloid treatment. The right choice depends on the scar’s size and maturity, where it sits on your body, whether it is causing symptoms and whether you have had previous treatment. These are the main options and how they compare.
Steroid Injections
Injections of a corticosteroid such as triamcinolone are the most widely used first-line treatment. The steroid reduces collagen production and softens and flattens the keloid, and it also relieves itching and tenderness. Treatment is typically given every four to six weeks for several sessions, so you should judge results over three to six months rather than after one visit. Smaller and newer keloids respond best; old, hard, long-established keloids are more resistant. Side effects can include temporary skin lightening, which is an important consideration for patients with darker skin tones and something your surgeon will discuss openly with you.
Silicone Gel Sheets and Gels
Medical-grade silicone, applied as a sheet worn for several hours a day or as a gel massaged into the scar, hydrates the scar surface and helps regulate collagen production. Silicone is painless, has virtually no side effects and is the standard treatment for early, thin keloids and for scars that are newly forming. Its main limitation is that it rarely flattens a thick, mature keloid on its own, so it is usually combined with injections or used after surgery to prevent recurrence.
Cryotherapy
Freezing the keloid with liquid nitrogen destroys the overactive scar tissue, and it is particularly useful for smaller keloids, especially on the ears. Multiple sessions are usually needed. Cryotherapy can be uncomfortable for a few days afterwards and carries a risk of temporary or occasionally permanent skin lightening, so it is chosen carefully depending on your skin tone and scar site.
Surgical Excision — With a Plan for Recurrence
Surgically removing a large, troublesome keloid can transform comfort and appearance, and for bulky scars it is often the only realistic way to achieve a flatter result. The critical point to understand is that surgery alone carries a high recurrence risk — a keloid can return larger than before. For this reason, surgery is almost always combined with follow-up treatment such as steroid injections into the healing wound, silicone therapy, pressure garments or earrings, and in stubborn cases radiotherapy. Excision works best when the surgeon removes the scar meticulously, closes the skin under minimal tension and commits to a structured aftercare plan.
Other and Combination Therapies
Laser therapy can soften redness and flatten early keloids and is sometimes combined with steroid injections. Pressure treatment, using specially fitted garments or clip-on pressure earrings, needs to be worn for many hours daily over months, but it is effective for earlobe keloids and after excision. Your surgeon may also discuss intralesional treatments such as 5-fluorouracil, sometimes combined with steroid, for resistant scars. At Precision Surgery we frequently use a combination approach, because keloids that have failed single treatments often respond when therapies are layered together in the right sequence.
Which Treatment Is Right for You?
As a general guide, a new, small or mildly raised keloid usually starts with steroid injections, silicone, or both. A soft, early keloid on the ear may do well with pressure therapy or cryotherapy. A large, dense, long-standing keloid on the chest or shoulder, or one that is painful, ulcerating or severely affecting your quality of life, may be best treated with surgical excision followed by a combination of injections, silicone and pressure to protect the result.
Your treatment plan also needs to account for your skin tone, your history of previous keloids, and your priorities. Some patients are content with flattening and symptom relief; others want the most refined cosmetic result possible. Both goals are entirely reasonable, and your consultation is where a realistic, personalised plan is agreed.
At your appointment, your surgeon will examine the scar, ask about how and when it formed, and review any previous treatments you have tried. Photographs are taken so that progress can be measured objectively at each review, and you will leave with a written plan outlining which treatments are recommended, in what order, over what timeframe, and what results you can reasonably expect.
Recurrence, Long-Term Care and Realistic Expectations
Honesty matters with keloids: they are a recurring condition, and no treatment can guarantee a scar will never return. What good treatment does is dramatically shift the odds in your favour. Most recurrences happen within the first year, which is why we review patients regularly after excision and continue protective treatment while the scar is young. Even when a keloid cannot be removed completely, flattening it, easing the itch and tenderness and fading its colour can make an enormous practical difference.
If you know you are prone to keloids, prevention for future wounds is worth planning too: avoid unnecessary piercings and cosmetic skin procedures in high-risk areas, treat any acne on the chest and shoulders promptly, and if you do need surgery, tell your surgeon in advance so that meticulous closure technique and early scar therapy can be arranged from day one.
