Keloids are overgrowths of scar tissue that form at the site of a skin injury. They can be unsightly, itchy, and sometimes painful. One of the most effective treatments for keloids is the injection of corticosteroids, specifically triamcinolone. This article provides an in-depth look at triamcinolone keloid injections, including their mechanism of action, procedure, benefits, potential side effects, and more.
Understanding Keloids
What are Keloids?
Keloids are thick, raised scars that can develop after skin injuries such as cuts, burns, surgical incisions, or even acne. Unlike regular scars, keloids extend beyond the original wound site and may continue to grow over time. They are more common in individuals with darker skin tones and can occur anywhere on the body, although they are most frequently found on the chest, shoulders, earlobes, and cheeks.
Causes and Risk Factors
The exact cause of keloid formation is not entirely understood, but it involves an abnormal response to skin injury. Factors that may increase the risk of keloid development include:
- Genetic predisposition
- Ethnicity (higher prevalence in African, Asian, and Hispanic populations)
- Hormonal changes
- Certain types of skin trauma (e.g., ear piercings, surgical wounds)
Introduction to Triamcinolone
What is Triamcinolone?
Triamcinolone is a corticosteroid used to reduce inflammation and suppress the immune response. It is commonly prescribed for conditions like eczema, psoriasis, arthritis, and allergies. In dermatology, triamcinolone is used to treat keloids and hypertrophic scars through intralesional injections.
How Does Triamcinolone Work?
Triamcinolone works by reducing inflammation and collagen production in the scar tissue. When injected directly into a keloid, it helps to flatten and soften the scar by:
- Reducing the activity of fibroblasts (cells responsible for collagen production)
- Decreasing the synthesis of extracellular matrix components
- Suppressing inflammatory cytokines that contribute to scar formation
The Injection Procedure
Pre-Procedure Consultation
Before undergoing triamcinolone injections, a consultation with a dermatologist or a qualified healthcare provider is necessary. During this consultation, the provider will:
- Assess the size, location, and characteristics of the keloid
- Review the patient’s medical history and any previous treatments
- Discuss potential risks, benefits, and expected outcomes
- Provide instructions for pre-procedure care, such as avoiding certain medications that may increase bleeding
The Injection Process
The actual injection process is relatively straightforward and typically takes only a few minutes. Here is what to expect during the procedure:
Preparation: The area around the keloid is cleaned with an antiseptic solution.
Anesthesia: Depending on the patient’s pain tolerance and the size of the keloid, a local anesthetic may be applied to minimize discomfort.
Injection: Triamcinolone is injected directly into the keloid using a fine needle. The dosage and concentration of the steroid depend on the size and severity of the keloid.
Post-Injection Care: The injection site may be massaged gently to distribute the medication. A small bandage may be applied to protect the area.
Frequency and Number of Treatments
Triamcinolone injections are usually administered in a series of treatments spaced several weeks apart. The exact number of injections required varies depending on the individual’s response to the treatment and the characteristics of the keloid. On average, patients may need 3 to 5 sessions, but some may require more.
Benefits of Triamcinolone Injections
Effectiveness
Triamcinolone injections are considered one of the most effective treatments for keloids. They can significantly reduce the size, thickness, and redness of keloids, improving both the appearance and symptoms such as itching or tenderness. Studies have shown that up to 70% of patients experience a noticeable improvement in their keloids after treatment.
Minimal Invasiveness
Compared to surgical removal of keloids, triamcinolone injections are minimally invasive. They do not involve cutting or suturing the skin, which reduces the risk of infection and further scarring.
Quick Procedure with Minimal Downtime
The injection process is quick, typically taking less than 15 minutes per session. Patients can resume their normal activities immediately after the procedure, making it a convenient option for those with busy schedules.
Potential Side Effects and Risks
Common Side Effects
Like all medical treatments, triamcinolone injections come with potential side effects. Most side effects are mild and temporary, including:
- Redness and swelling at the injection site
- Mild pain or discomfort during and after the injection
- Skin discoloration (hypopigmentation or hyperpigmentation)
- Thinning of the skin (atrophy) around the injection site
Less Common but Serious Side Effects
While rare, some patients may experience more serious side effects, such as:
- Infection at the injection site
- Allergic reactions to the medication
- Formation of small blood vessels (telangiectasia) in the treated area
Long-Term Risks
Repeated steroid injections over a long period can potentially lead to systemic absorption, although this is uncommon with intralesional injections. Patients with diabetes or other chronic conditions should discuss the risks with their healthcare provider.
Who Should Avoid Triamcinolone Injections?
Contraindications
Triamcinolone injections may not be suitable for everyone. Contraindications include:
- Active skin infections or untreated skin conditions in the injection area

Precautions
Patients should inform their healthcare provider about any medications they are taking, as some drugs may interact with corticosteroids. It’s also important to disclose any history of allergic reactions to medications or other medical conditions.
Alternative Treatments for Keloids
Surgical Excision
Surgical removal of keloids involves cutting out the scar tissue. This method carries a risk of the keloid returning, often larger than before. It is typically combined with other treatments, such as radiation therapy or steroid injections, to minimize recurrence.
Laser Therapy
Laser treatment can reduce the size and discoloration of keloids. It works by targeting blood vessels within the keloid, reducing redness and flattening the scar. Multiple sessions may be required for optimal results.
Cryotherapy
Cryotherapy involves freezing the keloid tissue with liquid nitrogen, causing it to shrink. This method is often used for smaller keloids and may be combined with steroid injections.
Silicone Gel Sheets and Pressure Therapy
Silicone gel sheets and pressure garments can help flatten and soften keloids over time. These methods are often used as adjunctive treatments following surgery or other primary therapies.
Radiation Therapy
Post-surgical radiation therapy can reduce the recurrence rate of keloids. It involves directing low-dose radiation to the site immediately after surgical excision, preventing excessive scar tissue formation.
Post-Treatment Care and Management
Immediate Aftercare
After receiving a triamcinolone injection, patients should:
- Keep the injection site clean and dry
- Avoid strenuous activities that may irritate the area
- Apply an ice pack if there is swelling or discomfort
