简要总结
This is a prospective, multi-site trial to be conducted at 2 clinical sites. Up to 20 subjects will receive study treatments. Following study treatments, follow-up visits will occur at 60, 90 and 180 days from each subject's last study treatment.
详细描述
Subjects with moderate to severe atrophic acne scars will be enrolled. Subjects will receive up to three dual-depth treatments to the cheek and temple areas impacted by acne scars, treating the number of treatment squares necessary to cover the area of scarring. Each treatment square will receive 30 lines per transducer depth for a total of 60 lines per treatment square. Three treatments 30 days apart will be required.
