PubMed Reference: Chang YC, Lee SJ, Chung HJ. J Cosmet Laser Ther. 2018 Feb;20:21-23.

Study Details: 

  • 3 Asian subjects with 585 nm PDL-induced purpura after treatment of acne erythema.
  • Treated with 595 nm Vbeam at 3 days (Figure below - case 1), 2 days (case 2) or same day (case 3) following PDL-induced purpura.
  • All patients had clinically-significant improvement following 1 or 2 Vbeam treatments with 595nm.
  • Treatment with 595nm PDL, which targets hemoglobin and its breakdown products, after initial PDL treatment may reduce post-PDL purpura & speed the resolution of purpura.
