Conditions

Outcome Measures

Primary Outcomes (1)

  • Change in acne scarring compared to baseline after treatments

    The change in acne scarring is measured using a quantitative global scarring grading system to compare baseline to the treatment.

    Baseline and 36 weeks

Study Arms (2)

Multiple Subcision

EXPERIMENTAL

Subjects will receive multiple subcision treatments to their randomized side of the face 5 times total spaced 4 weeks apart.

Procedure: Multiple Subcision

Control

NO INTERVENTION

Subjects will receive no intervention control on the other side of the face.

Interventions

At the start of the procedure, a straight vitrectomy knife will be inserted subdermally and will be slowly advanced parallel to the dermis. Rapid advancement and retraction of the needle under the scarred area in a lancing motion will be performed to abrade the underside of the dermis followed by side to side sweeping motions attempting to break any fibrous attachments to the deeper tissues.

Multiple Subcision
