Primary Outcome Measures :
  1. 2 level improvement of cellulite severity on photonumeric scale [ Time Frame: Day 22, Day 43, Day 90, and Day 180 ]
    Proportion of responders defined as subjects with an improvement in cellulite severity from baseline of at least 2 levels of severity on the Investigator-rated Clinician-Reported Photonumeric Cellulite Severity Scale (CR-PCSS) with ratings raging from 0 (none), 1 (almost none), 2 (mild), 3 (moderate), to 4 (severe). A 2-level improvement would be for example a change from 4 (severe) to 2 (mild).


Other Outcome Measures:
  1. 1 level improvement of cellulite severity on photonumeric scale [ Time Frame: Day 22, Day 43, Day 90, and Day 180 ]
    Proportion of responders defined as subjects with an improvement in cellulite severity from baseline of at least 1 level of severity on the Investigator-rated Clinician-Reported Photonumeric Cellulite Severity Scale (CR-PCSS) with ratings raging from 0 (none), 1 (almost none), 2 (mild), 3 (moderate), to 4 (severe). A 1-level improvement would be for example a change from 4 (severe) to 3 (moderate).

  2. Subject Satisfaction with Cellulite Treatment [ Time Frame: Day 180 ]
    At Day 180, subjects will rate their satisfaction with cellulite treatment using the 5-point subject satisfaction scale. Ratings could be satisfied (+1), very satisfied (+2), neither satisfied nor dissatisfied (0), or dissatisfied (-1), very dissatisfied (-2).
