Intralesional Steroids

At Livingstone Dermatology, we understand that your skin is a reflection of your health and well-being. We are committed to the latest advancements in dermatological science, and dedicated to providing you with quality care.

What are Intralesional Steroids?

Some skin conditions do not respond well to creams or may take a long time to improve. In these cases, doctors or dermatologists sometimes recommend intralesional steroid injections. This treatment involves placing a small amount of corticosteroid medication directly into the skin lesion, targeting the problem at its source. By acting locally rather than throughout the whole body, the treatment provides strong results while keeping side effects to a minimum.

How do Intralesional Steroids work?

Steroids are powerful anti-inflammatory medicines, but when applied to the surface of the skin, they cannot always reach deeper lesions. Injecting them into the affected area allows the medicine to act exactly where it is needed. 

On a cellular level, corticosteroids:

What conditions can Intralesional Steroids treat?

Because the injection works directly within the lesion, they are effective for a variety of stubborn skin problems. Our dermatologists commonly recommend them for:

  • Alopecia areata – to stimulate hair growth in patches of hair loss.
  • Granuloma annulare – to reduce ring-shaped inflammatory lesions.
  • Haemangiomas – to shrink vascular growths.
  • Inflammatory acne lesions – to shrink painful cyst and nodules quickly.
  • Keloids and hypertrophic scars – to flatten and soften raised scars.
  • Lichen planus and lichen simplex – to calm itchy and inflamed patches.
  • Psoriasis plaques – especially thick or resistant ones.

Intralesional steroid injections may also be used for other stubborn lesions that fail to respond to creams or oral medicines.

Intralesional steroid injections are effective at treating keloid scars as the medicine softens thickened tissue for a smoother appearance.

What are the benefits of Intralesional Steroids?
 

Many patients turn to these options after discovering that creams or tablets are insufficient. Some of the advantages of the treatment include:

  • Effective for resistant lesions such as thick scars or deep, inflamed acne nodules.
  • Fewer overall side effects compared to oral steroids.
  • Improved appearance that can boost confidence.
  • Quick, in-clinic procedure with minimal downtime.
  • Relief symptoms like itching, swelling and discomfort.
  • The medicine works directly at the treatment site.

What are the possible risks and side effects of Intralesional Steroids?

As with all medical procedures, intralesional steroid injections have some risks. Most are mild and temporary, but it is helpful to be aware of them.

This may include:

  • Dilated tiny blood vessels (telangiectasia).
  • Infection or allergic reaction.
  • Lightening of the skin, especially noticeable in darker skin tones.
  • Small surface depressions if the steroid is unevenly distributed.
  • Tenderness or bruising at the injection site.
  • Thinning of the skin in the treated area.

How are Intralesional Steroid injections administered?

An intralesional steroid injection is usually a quick and in-clinic procedure that does not require hospitalisation. Each step is designed to be as comfortable and safe as possible:

  • Preparation of the skin – the area is cleansed thoroughly with an antiseptic to lower the risk of infection.
  • Pain control – depending on the site and sensitivity of the lesion, a numbing cream or a small injection of local anaesthetic may be used. This ensures the procedure is well tolerated, even in delicate areas like the face or scalp.
  • Precise injection – a very fine needle is used to deliver a controlled amount of steroid directly into the lesion. If the patch is larger, thicker or irregular in shape, our dermatologist may use multiple small injections to distribute the medicine evenly.
  • Tailored dosing – the strength and volume of the steroid are carefully chosen based on the condition, location and size of the lesion, ensuring maximum benefit with minimal side effects.
  • Post-treatment care – once the injection is complete, the site may be covered with a small dressing. Most patients can return to work, school or their daily activities straight away with no downtime.

What to expect after an Intralesional Steroid injection?

Most people recover quickly after intralesional steroid treatment and can return to normal activities immediately. In the hours and days that follow, you may notice:

  • Mild soreness or swelling at the injection site, which usually settles within a day or two.
  • Gradual improvement in the lesions as the treated area begins to soften, flatten, shrink or lose redness over the next few days to weeks.
  • Symptom relief with less itching, pain or tenderness, making the skin feel more comfortable.
  • Visible cosmetic changes such as scars becoming flatter, acne cysts shrinking and in cases of alopecia areata, a reduction in bald patches.

What results can you expect?
 

Outcomes vary depending on the skin concern being treated. Our patients often see steady and meaningful improvement, which may include:

  • Raised scars gradually become flatter, softer and less red.
  • Areas of hair loss may begin to show regrowth within the treated patches.
  • Painful acne nodules often shrink noticeably within a few days.
  • Inflamed plaques such as psoriasis or lichen planus calm over several weeks with less redness, scaling or thickening.

Although the results are not immediate, most people notice visible changes that improve with time and ongoing sessions.

How many sessions are needed?

The number of treatments depends on the individual condition and how the skin responds. This includes:

  • A single session may be enough for smaller acne nodules.
  • A course of injections is often recommended for scars, alopecia areata or persistent plaques. The sessions usually span 4 to 6 weeks apart.
  • Maintenance treatments may be advised for conditions that tend to recur, helping to keep symptoms under control.

Frequently Asked Questions

Is the injection painful?

Most patients describe intralesional steroid injections as a quick pinch or mild sting. The discomfort is usually brief and well-tolerated. If you are sensitive to pain, our dermatologist can apply a numbing cream or a small local anaesthetic to make the process more comfortable.

Some people notice improvements within a few days, especially for painful acne nodules or inflamed cysts. For conditions like scars or alopecia areata, changes develop more gradually over a few weeks as the skin responds to treatment.

It depends on the condition and its severity. A single session may be enough for smaller acne lesions, but conditions such as keloids, hypertrophic scars or alopecia areata often require several injections spaced four to six weeks apart.

Results can be long-lasting, particularly for scars that flatten and soften permanently. In conditions that may come back, such as alopecia areata or psoriasis, follow-up or maintenance sessions may be recommended to keep the condition under control.

Intralesional steroids are considered safe when given by our dermatologist. However, your medical history, skin type and specific condition will be assessed first to ensure it is the right option for you. Pregnant women, breastfeeding mothers or patients with certain medical conditions may need alternative treatments.

The injection itself does not create a scar. On the contrary, intralesional steroids are often used to treat raised or thickened scars, helping them to flatten and blend more naturally with the surrounding skin.

This treatment is effective for a range of stubborn conditions, including keloids, hypertrophic scars, alopecia areata, cystic acne, psoriasis plaques, lichen planus, granuloma annulare and inflamed skin nodules.

Most injections are completed within minutes during a clinic visit. You can return to work, school or daily activities right after the appointment, making it a convenient option for busy patients.

Costs can vary depending on the size, number and type of lesions being treated. Your dermatologist will provide a clear estimate after assessing your condition during consultation.
