Intralesional injections are targeted dermatological procedures in which medication is delivered directly into a specific skin lesion to achieve concentrated therapeutic effect. This approach is commonly used in the management of keloids, hypertrophic scars, inflammatory acne nodules, alopecia areata patches, cystic lesions, and certain benign growths. By injecting medication precisely into the affected tissue, intralesional therapy minimizes systemic exposure while maximizing localized response.

Keloids and hypertrophic scars represent one of the most frequent indications. These scars result from excessive collagen production during wound healing and may extend beyond the original injury site. Patients often experience itching, tenderness, cosmetic concern, and progressive thickening. Intralesional therapy works by reducing collagen synthesis, decreasing inflammation, and flattening raised tissue over time.

Before treatment, a detailed dermatological evaluation determines lesion type, age, size, and symptom burden. Treatment intervals and dosing are individualized based on lesion characteristics and prior response history. Patients are counseled on expected gradual improvement rather than immediate transformation.

The procedure itself is performed in an outpatient setting using a fine needle to deliver medication into the lesion. The session is brief and requires minimal preparation. Mild discomfort may occur during injection, but it is generally well tolerated. After treatment, temporary swelling or localized sensitivity may be present for a short period.

Multiple sessions are often required for optimal results, particularly in large or longstanding keloids. Follow-up allows monitoring of response and adjustment of dosage or frequency. Combination approaches may be considered for resistant lesions to improve outcomes.

One advantage of intralesional injections is precision. Instead of treating large skin areas, therapy is localized to the problem tissue. This makes it ideal for patients seeking non-surgical scar management options with minimal downtime.

Expected outcomes include reduction in scar height, improved texture, symptom relief, and enhanced cosmetic appearance. Early intervention often yields better results than treating very mature scars.

Intralesional injections provide effective, minimally invasive lesion control when carefully selected and professionally administered. With proper evaluation and monitoring, this technique significantly improves symptomatic and cosmetic dermatological concerns.
