At $180 per visit, intralesional steroid injections represent a mid-range cost option for treating keloid acne scars—those thick, raised scars that extend beyond the original wound boundaries. This price point typically covers a single treatment session where a dermatologist injects corticosteroids directly into the keloid tissue to flatten and soften the scar. A person with three or four significant keloids on their chest or shoulders might expect to spend $540 to $720 for an initial treatment round, which often requires multiple sessions spaced weeks apart for optimal results. The cost is reasonable compared to surgical removal (which can run $500–$2,000 per scar) but more expensive than topical treatments or laser work, making it a popular middle-ground choice for patients seeking noninvasive reduction of keloid thickness.
The $180 price typically includes the physician’s assessment, the injection procedure itself, and follow-up evaluation. Costs may vary depending on whether you’re treating one small keloid or multiple larger scars, your geographic location, and whether your dermatologist charges by individual keloid or by session. Insurance coverage for steroid injections is inconsistent; some plans cover it as a medical necessity for symptomatic keloids, while others classify it as cosmetic, leaving you to pay out of pocket. Understanding what’s included in that $180 visit can help you decide whether the investment makes sense for your specific situation.

What Are Intralesional Steroid Injections for Keloid Scars?
Intralesional steroid injections involve injecting corticosteroid medication directly into the body of a keloid scar. The most commonly used steroid for this purpose is triamcinolone acetonide, typically at a concentration of 10–40 mg/mL. A dermatologist uses a very fine needle to place the medication into the core tissue of the keloid, where it works to suppress the excessive collagen production and inflammation that make keloids grow and remain thick. This is fundamentally different from topical steroid creams, which sit on the surface of skin and cannot penetrate deep enough to affect internal scar tissue.
Keloids are pathological scars that result from an overzealous healing response. Unlike normal scars, which gradually flatten and fade over years, keloids continue to grow beyond the original injury site, becoming raised, firm, and sometimes itchy or tender. acne scars that develop into keloids are particularly stubborn because acne lesions themselves trigger inflammation deep in the skin. Intralesional steroid injections interrupt the inflammatory and proliferative signals that fuel keloid growth, gradually causing the scar tissue to soften and flatten. A typical keloid may require three to six injections spaced three to four weeks apart to see meaningful improvement, which means your true out-of-pocket cost could reach $540 to $1,080 for a complete treatment course on a single scar.
How Intralesional Steroid Injections Treat Keloid Acne Scars
The mechanism behind these injections is rooted in how corticosteroids suppress immune and inflammatory responses in the skin. When injected directly into a keloid, the steroid reduces the activity of fibroblasts—the cells responsible for producing collagen. It also decreases inflammatory cytokines and growth factors that perpetuate scar tissue proliferation. Over the course of weeks and months, this suppression leads to visible flattening, softening, and reduced redness in the keloid. Some keloids flatten significantly, while others reduce in size and firmness but do not disappear entirely. Clinical studies on triamcinolone injection for keloids show success rates of 40–60% for substantial improvement, depending on scar characteristics and how early treatment begins.
Newer, smaller keloids tend to respond better than large, established ones that have been present for years. For example, a person who had acne five years ago and developed a quarter-inch-thick, dome-shaped keloid on their shoulder may see a 30–40% reduction in height after a complete treatment series, whereas someone treating a keloid that emerged just six months prior might achieve 60–70% flattening. The steroid injection works best when combined with other therapies, such as silicone gel pads or pressure garments worn after each injection, which reinforce the anti-proliferative effect. One important limitation is that intralesional steroids do not work equally well for all keloid types or on all skin tones. Keloids are significantly more common and more aggressive in people with darker skin, and anecdotal evidence suggests that treatment response may be slower or less complete in these populations, though research on this disparity remains limited. Additionally, keloids on certain body areas—the chest, shoulders, and earlobes—tend to be more resistant to steroid injection than those on the face or arms, possibly due to differences in blood supply and skin tension in those zones.
Understanding the $180 Per-Visit Cost Structure
The $180 per-visit cost reflects several factors: the dermatologist’s expertise and time, the pharmaceutical cost of the corticosteroid medication, the clinical infrastructure required to administer injections safely, and geographic variation in healthcare costs. In major metropolitan areas like new York or Los Angeles, a single steroid injection session might run $200–$300, while in smaller towns or rural areas, the same procedure could be $120–$160. Teaching hospitals and academic dermatology clinics often charge less—sometimes as low as $100–$150 per visit—whereas private cosmetic dermatology practices may charge more. Insurance reimbursement further complicates the cost picture.
If your dermatologist can document that the keloid is symptomatic (causing pain, itching, or functional impairment), there is a stronger case for insurance coverage. Some insurers will cover three to four injections per keloid per year, making your out-of-pocket cost zero to your co-pay amount. However, if the keloid is considered purely cosmetic—even if it bothers you emotionally—many insurers will deny the claim outright. It’s worth calling your insurance company before scheduling to ask whether intralesional steroid injections for acne-related keloids fall under your plan’s coverage. Paying out of pocket for a series of six injections at $180 each costs $1,080, which is why some patients opt for fewer injections or spread treatments over a longer timeline to manage costs.
What to Expect During and After Treatment
During an intralesional steroid injection session, your dermatologist will likely apply a topical numbing cream to the keloid area five to ten minutes before the procedure, so you feel minimal discomfort during the injection itself. The actual injection takes one to five minutes, depending on the number and size of keloids being treated. You may feel a brief stinging sensation as the needle enters, followed by a dull pressure as the steroid solution is deposited into the scar tissue. Most people describe the sensation as tolerable—less uncomfortable than a typical acne extraction or mole removal.
After the injection, you can typically return to normal activities immediately. Some dermatologists recommend avoiding heavy exercise or excessive sweating for 24 hours, and you should not massage or apply pressure to the injected area for at least a week. Mild redness, swelling, or bruising at the injection site is common and resolves within a few days. More importantly, you will not see dramatic flattening overnight; the steroid takes two to four weeks to noticeably soften the keloid tissue. Comparing this to surgical removal, which produces immediate results but involves downtime, pain, and a risk of keloid recurrence (up to 50% of surgically removed keloids return), steroid injections offer a gentler approach even if it requires patience.
Potential Side Effects and Limitations of Steroid Injections
While intralesional steroid injections are generally considered safe for localized treatment, they do carry potential side effects. The most common local side effect is subcutaneous atrophy—a thinning or depression in the skin around the injection site—which occurs in 5–10% of cases when the steroid dose or frequency is too high or when the injection penetrates into the dermis rather than remaining in the scar tissue itself. In darker skin types, corticosteroid injections can occasionally trigger hypopigmentation (white spots) or hyperpigmentation (darkening) in the treated area, adding a cosmetic concern atop the original keloid issue. Systemic absorption of the steroid is rare with intralesional injection because the medication is deposited locally in scar tissue, not intravenously.
However, patients with diabetes, immunosuppression, or active skin infections should inform their dermatologist before treatment. Additionally, there is a small risk that steroid injection could exacerbate active acne in the surrounding area, so keloid treatment is ideally deferred until acne is under control. A major limitation that sometimes goes unmentioned is that steroid injections do not permanently eliminate keloids; they reduce their size and symptoms, but without maintenance treatments or additional therapies, some keloids gradually regrow over one to three years. This means you may need periodic “touch-up” injections every 12–24 months to maintain results.
How Steroid Injections Compare to Other Keloid Treatments
Several treatment modalities exist for acne keloids, and steroid injection is just one option in a multimodal toolkit. Surgical excision is the most definitive approach but carries a 40–50% recurrence rate if not combined with adjunctive treatment like radiation or additional steroid injections. Laser therapy (specifically pulsed dye laser or Nd:YAG) can improve the redness and flatten keloids somewhat but is less effective for thick, dome-shaped scars and typically costs $300–$500 per session. Silicone gel pads or sheets, which cost $20–$50, work slowly over months but involve no medication or needles and can be used alongside steroid injections for synergistic benefit.
A person deciding between options might weigh cost, downtime, permanence, and scar characteristics. If you have a small, fresh keloid and want to avoid injections, silicone pads alone might suffice over six months to a year. If you have large, established keloids and want the fastest results, surgical excision followed by steroid injections and radiation therapy could be the most effective route—but would cost several thousand dollars. Intralesional steroid injections, at $180 per visit, occupy a middle ground: moderate cost, no downtime, gradual but reliable results, and low risk of serious complications, making them appealing to many patients who want to avoid the commitment or expense of surgery.
Long-Term Results and Treatment Planning
Long-term results from intralesional steroid injections for acne keloids are encouraging but not miraculous. Studies tracking patients for two to five years show that 50–60% of keloids achieve a 50% or greater reduction in size, roughly 25–30% achieve 25–50% reduction, and 10–15% show minimal improvement. The timeline matters: visible improvement typically emerges at the four-week mark, with maximal benefit often not apparent until 12 weeks after the final injection.
Some dermatologists recommend a “test” injection on one keloid first to gauge your individual response before committing to treatment of multiple scars. Looking forward, the combination of intralesional steroids with emerging therapies—such as botulinum toxin injections (which may reduce mechanical tension and keloid proliferation) or newer targeted biologic agents that interfere with specific growth factors—shows promise in research settings. For now, if you are considering steroid injections for acne keloids, realistic long-term planning involves committing to a series of injections over three to four months, accepting a 40–60% improvement likelihood, and remaining open to periodic maintenance treatments or combination with other modalities if your results plateau. This approach prevents the disappointment that can arise when someone expects steroid injections to completely erase a keloid after one or two sessions.
Conclusion
Intralesional steroid injections at $180 per visit offer a practical, moderately priced option for reducing the appearance and symptoms of acne-related keloid scars. The procedure is quick, has minimal downtime, and carries few serious side effects when administered by an experienced dermatologist.
Most patients require a series of three to six injections spaced weeks apart, bringing the total cost to $540–$1,080 for meaningful improvement, though insurance coverage can significantly reduce this burden if the keloid meets medical-necessity criteria. Before booking your first injection, consult with a dermatologist to assess your specific keloid characteristics, discuss realistic expectations for your skin type and scar location, and clarify the total cost including all planned sessions. If intralesional steroid injections alone do not achieve your desired result, you and your dermatologist can plan a combined approach incorporating pressure garments, laser therapy, or other adjunctive treatments to maximize your outcome.
