Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: 532nm KTP Laser vs 595nm Pulse Dye Laser<br>This is a single-center prospective, randomized, controlled split-face study in 20 subjects diagnosed with Erythematotelangiectatic Rosacea and/or Papulopustular Rosacea. This two arm, split-face study will consist of: Treatment arm involving treatments with 532nm KTP laser Active control arm involving treatments with 595nm Pulse Dye Laser (PDL) Each subject's face will be divided in half and labeled as A (Right Side of the Face) or B (Left Side of Face). The allocation of treatment (532nm KTP laser) and active control treatment (595nm PDL) arms will be determined by randomization. | Device: 532nm KTP Laser vs 595nm Pulse Dye Laser<br>* Intervention for the Cutera Excel V system is to cease treatment to any subject that is experiencing any adverse reaction.<br>|
