Lutronic PicoPlus Exploratory Clinical Trial

This pilot clinical trial will evaluate the capability of the Lutronic PicoPlus technology to
remove unwanted tattoos and benign pigmented lesions. This trial is designed as a
multi-center exploratory, open-label clinical trial comparing each subject's condition before
and after treatment. Subjects meeting all entrance criteria will be assigned to Group A for
treatment of unwanted tattoos and Group B for treatment of unwanted benign pigmented lesions,
melasma, or other skin conditions such as skin rejuvenation. Subjects in each treatment group
will receive a series of treatments, e.g., 2-5, and will be asked to complete 1 and 3 month
follow-up visit(s) following each treatment to assess treatment efficacy and safety. At
investigators' discretion, additional follow-up visits, e.g., at 6 months following
treatment, may take place to observe the time course of reactions after treatment and/or
assess efficacy. Outcome measures include clinician grading and subject satisfaction
post-treatment. Pre-treatment study photos will be obtained at baseline; post-treatment study
photos will be obtained at each post-treatment follow-up visit.
