Treatment for Acne Cysts and Scars

An intralesional steroid injection involves a corticosteroid such as triamcinolone acetonide injected directly into a lesion on or immediately below the skin. It delivers anti-inflammatory and collagen reducing substances into the skin to help with acne cysts and scarring conditions like hypertrophic scars. In Australia, steroid injection is available in 2 strengths: 10 mg per ml and 40 mg per ml.
