Background: Milia are a usual consultation in dermatologic practice and optimal treatment modalities are not established.
Objective: To evaluate the efficacy and the safety of CO(2) laser vaporization in the treatment of milia.
Methods: We report four patients, aged from 12 to 50 years old, with different variants of milia: milia en plaque, milia post-photodermatitis, multiple eruptive milia and milia post-trauma. They were treated with the CO(2) laser in superpulsed and focused mode at 2 W/cm(2), with two passes in each session. The follow-up was 12-36 months.
Results: All patients showed marked improvement after a few sessions of CO(2) laser. No-one had recurrence or noticeable side effects.
Conclusion: The CO(2) laser is an option in adult and child patients with multiple milia lesions or milia en plaque, obtaining good cosmetic results with minimal side effects.
