Clinical Study to Evaluate Different Energy-based Devices for Aesthetic Treatments.

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.

* Received fillers or neurotoxin injections in the treatment area within the past 2 weeks.
* Has had a chemical or mechanical epilation within the last six weeks.
* Currently enrolled in an investigational drug or device trial or has received an investigational drug or been treated with an investigational device within the area to be treated 6 months to entering this study.
* Has any condition or is in a situation which in the investigator's opinion may put the subject at significant risk, may confound study results or may interfere significantly with the subject's participation.

Radiofrequency Device Only:

* Has a Pacemaker
* Has any embedded electronic devices that give or receive a signal.
* Has electronic implants, such as Implantable Cardiac Defibrillators (ICD) or Cardiac Resynchronization Therapy (CRT) devices: treatment may interfere with the functionality of the device and/or damage the electronic implant.
* Is allergic to adhesives such as glues on medical tape: they should be alerted that a rash may occur on the neutral electronic monitoring pad (NEM or neutral pad) site, and an over-the-counter preparation may be used to treat the area.
* Has nerve insensitivity to heat in the treatment area or in the neutral pad placement area.
* Is allergic to topical anesthetic
