clinical study to evaluate different energy-based devices for aesthetic treatments.

Conditions: Dermatologic Conditions

Summary: the goal of the energy-based devices used in this study is to evaluate their safety and performance to treat unwanted dermatologic conditions.

up to 50 subjects will be enrolled at 1 study center. subjects will be enrolled into 4 groups: group a, group b, group c, or group d. subjects may enroll in more than one group, however the last treatment in the previous group would be at least 30 days before the subject is enroll in the next group if treatment area is the same.
