Primary outcomes

  1. Tattoo Clearing at 6 Weeks Post-final Laser Treatment for Each Treatment Arm as Assessed by Blinded Reviewers.

    Time frame: 6-weeks post-final treatment

    Physician's Global Assessment Scale: 0 (min) - 4 (max) Higher scores represent better tattoo clearing 4 = Very Significant Clearing (> 75%) 3 = Significant Clearing (51 - 75%) 2 = Moderate Clearing (26 - 50%)

    1 = Mild Clearing (5 - 25%) 0 = No Change (< 5%)

Secondary outcomes

  1. Comparison of Subject Discomfort (Pain) Between Treatment and Active Control Treatment Arms During Treatment

    Time frame: During treatment, approximately 10 minutes

    Numeric Pain Rating Scale (Min=0; Max=10) Higher scores mean worse outcome
