What are intralesional injections?
Intralesional injections contain a corticosteroid, and are injected into a lesion on the skin in order treat dermal inflammation and improve the appearance of the skin.
How do they work?
When an intralesional injection is administered, the medicine is injected directly into the area of skin that needs to be treated. The medicine is injected by means of a very thin needle, which allows a high level of precision into the area of skin that requires treatment.
The medicine used in intralesional injections is a type of steroid known as a corticosteroid, which works by reducing inflammation and the amount of collagen in the skin. Because the steroid is injected directly into the problem area of skin, this treatment is more effective than topical steroid creams and ointments.
Several intralesional injections may be required, depending on the condition for which you are being treated, as well as the size of the area that requires treatment.
It is quite normal to feel some mild discomfort after the injection and you may notice a small amount of bleeding at the site of injection. Although infection is rare, let your dermatologist know if you experience severe pain or if an abscess develops, as this will need to be treated with antibiotics. In some cases, patients may notice a change in pigmentation at the site of injection, and the skin may either lighten or darken.
Why are they administered?
Intralesional injections are often recommended to treat a range of skin conditions. These include acnes lesions, cysts, alopecia, eczema, skin lupus, psoriasis, and some kinds of scars.
