Acne is a common skin condition that affects millions of people across the globe. Its impacts range from mild discomfort and cosmetic concerns to deep, painful nodules and cysts that can cause long-lasting scars. For many, traditional treatments like topical treatments or oral medications may not be enough to control deep, inflamed acne lesions. In such instances, a quick and highly effective solution can be found in Kenalog injections (intralesional triamcinolone), a treatment offered by many dermatologists for stubborn acne lesions.
In this article, we’ll explore everything you need to know about Kenalog injections for acne — what they are, how they work, their benefits and risks, and when this treatment might be the best option for your skin.
What is Kenalog?
Kenalog is a brand name for triamcinolone acetonide, a potent corticosteroid medication used to reduce inflammation and suppress the immune system in various medical treatments. In dermatology, it is administered as an intralesional injection — a tiny, precisely targeted injection administered directly into a pimple, nodule, or cyst.
Kenalog works by reducing the swelling, redness, and discomfort associated with inflamed acne lesions, making it ideal for treating:
-
Large, deep pimples
-
Cystic acne
-
Inflammatory nodules
-
Persistent acne that doesn’t respond well to topical treatments
How Do Kenalog Injections Treat Acne?
Acne occurs when pores become clogged with excess oil, dead skin, and bacteria, triggering an inflammatory response from the body. This leads to swelling, redness, and sometimes pain. In the case of cystic acne, the lesion can be deep and stubborn, making it difficult for topical treatments to penetrate.
Kenalog, as a corticosteroid, reduces the local immune response and decreases the release of inflammatory chemicals. When injected directly into the acne lesion, it:
-
Reduces swelling.
-
Alleviates discomfort.
-
Speeds up the healing process.
-
Helps flatten the lesion within 24–72 hours.
In many instances, patients notice significant improvement within a day or two after receiving the injection.
What to Expect During a Kenalog Injection Appointment
If your dermatologist determines that a Kenalog injection is an appropriate treatment for your acne, here’s an overview of the procedure:
1. Consultation
Your doctor will assess the acne lesion and determine if it’s a suitable candidate for an intralesional steroid injection. Kenalog is generally used for larger, inflamed cystic lesions that cause discomfort and have not responded well to other treatments.
2. Cleaning the Area
The area around the acne lesion will be cleansed with an alcohol swab to reduce the risk of infection.
3. Injection
A very fine needle is used to inject a tiny amount of the steroid solution directly into the acne lesion. The quantity of Kenalog used is highly precise, minimizing the risk of side effects.
4. Aftercare
Patients can generally return to normal activities immediately after the procedure. The treated lesion should shrink within 24–72 hours.
Benefits of Kenalog Injections for Acne
Kenalog injections have become popular due to their quick and targeted effectiveness. Here are some benefits:
-
Rapid Reduction of Inflammation: Results can be seen within a day or two, making it ideal for people with urgent needs (e.g., before an important event).
-
Targeted Treatment: Works directly on the problem area, avoiding systemic side effects.
-
Pain Relief: Reducing the size and pressure of the lesion can alleviate discomfort and tenderness.
-
Short Recovery Period: Most patients experience minimal downtime and no significant restrictions post-treatment.
-
Reduced Risk of Scarring: By quickly decreasing the lesion’s size and depth, Kenalog injections can help reduce the risk of long-term scarring.
Potential Side Effects of Kenalog Injections for Acne
Although Kenalog injections are generally safe when administered correctly, it’s important to be aware of potential side effects:
1. Atrophy and Depression of the Skin
The most common side effect is a depressed area or divot at the site of the injection due to the steroid causing loss of collagen and subcutaneous tissue. This can occur if too much steroid is administered or if it’s injected too superficially.
How long does it last?
Most depressions resolve within a few months, although in rare cases, the indentation can be long-lasting.
2. Skin Discoloration
Some patients, especially those with darker skin tones, may experience hypopigmentation (lighter patches) or, rarely, hyperpigmentation (darker patches) at the site of the injection.
3. Temporary Redness and Bruising
As with any injection, mild bruising or redness can occur and typically resolves within a few days.
4. Systemic Side Effects
Although rare due to the tiny dose used, systemic effects such as hormonal disturbances can occur if multiple injections are administered across large areas.
When to Consider Kenalog Injections for Acne
Kenalog injections are not intended for every acne breakout. Instead, they are best suited for:
-
Large, painful acne cysts.
-
Lesions that have been persistent for weeks or months despite other treatments.
-
Patients seeking quick improvement for special occasions.
-
Situations where traditional treatments have failed or are contraindicated.
Important Note: Kenalog injections are NOT a substitute for a long-term acne treatment regimen. They are best used as a spot treatment in combination with other treatments, such as:
-
Topical treatments: Retinoids, salicylic acid, and benzoyl peroxide.
-
Oral treatments: Antibiotics, hormonal treatments, or isotretinoin.
-
Light and laser treatments.
How Frequently Can You Get Kenalog Injections?
Kenalog injections can be administered every 4–6 weeks if needed. However, it is generally recommended to limit their use due to the risk of skin thinning or indentation over time. Always consult with a qualified dermatologist to assess if and when a Kenalog injection is appropriate for your acne.
Cost of Kenalog Injections for Acne
The cost of a Kenalog injection can vary based on geographic location, the expertise of the provider, and the number of lesions treated. In the United States, the cost can range from $50 to $150 per lesion. In other countries or clinical settings, pricing may be different. It is always best to confirm the cost and discuss insurance or payment options with your provider beforehand.

5. Are Kenalog injections covered by insurance?
It depends on your insurance plan and the medical necessity of the injections. Consult your provider for details.
The Role of Kenalog Injections in an Overall Acne Treatment Plan
Kenalog injections can be a valuable part of an acne treatment regimen when used appropriately. Ideally, these injections are used to manage:
-
Severe, painful breakouts.
-
Large cystic acne lesions.
-
Flare-ups that require quick intervention.
For long-term acne control, dermatologists often combine Kenalog injections with treatments such as:
-
Topical treatments: Retinoids, salicylic acid, or azelaic acid.
-
Oral treatments: Antibiotics, spironolactone, or isotretinoin.
-
Light therapy and chemical peels: To maintain long-term skin health.
How to Minimize the Risk of Side Effects
Here are some tips to reduce the risk of side effects from Kenalog injections:
-
See an experienced, licensed professional.
Proper technique and dosing are crucial for minimizing side effects. -
Limit the number of injections.
Avoid treating the same area too frequently. -

Your doctor may recommend applying ice to reduce swelling or using a gentle skincare routine post-injection. -
Report any changes to your doctor.
If you notice indentation, discoloration, or other side effects, consult your doctor promptly.
Final Thoughts
Kenalog injections can be a highly effective and quick solution for treating stubborn, inflamed acne lesions. When administered by a trained professional, this treatment can reduce discomfort, minimize scarring, and help restore clearer, smoother skin within a matter of days.
However, it’s important to remember that Kenalog injections are a complementary therapy, not a standalone or long-term solution for acne. Patients dealing with recurring acne outbreaks should work closely with their dermatologists to create a tailored treatment plan that addresses both the symptoms and the underlying causes of acne.
