Acne vulgaris is a common chronic skin disease involving blockage and/or inflammation of pilosebaceous units (hair follicles and their accompanying sebaceous gland). Acne can present as noninflammatory lesions, inflammatory lesions, or a mixture of both, affecting mostly the face but also the back and chest
These therapies may be suggested in select cases, either alone or in combination with medications.
- Lasers and photodynamic therapy. A variety of light-based therapies have been tried with some success. But further study is needed to determine the ideal method, light source and dose.
- Chemical peel. This procedure uses repeated applications of a chemical solution, such as salicylic acid, glycolic acid or retinoic acid. Any improvement in acne is not long lasting, so repeat treatments are usually needed.
- Extraction of whiteheads and blackheads. Your doctor may use special tools to gently remove whiteheads and blackheads (comedos) that haven't cleared up with topical medications. This technique may cause scarring.
- Steroid injection. Nodular and cystic lesions can be treated by injecting a steroid drug directly into them. This therapy has resulted in rapid improvement and decreased pain. Side effects may include thinning in the treated area.
