BACKGROUND Rosacea is a common inflammatory skin condition affecting approximately 5% of the world population. Therapeutic approaches to rosacea are focused on symptom suppression by means of anti-inflammatory agents. More recently, photodynamic therapy, especially light-emitting diodes, has been introduced as a valid alternative to conventional therapy. CASE PRESENTATION In the present work, we reported the efficacy and safety of light-emitting diodes therapy combining blue (480 nm) and red (650 nm) light for the treatment of two patients with papulopustular rosacea: a 22-year-old Caucasian woman and a 68-year-old Caucasian man. CONCLUSIONS This kind of treatment could represent an effective, safer, and well-tolerated approach for the treatment of such conditions.
