Compare the effectiveness of nonablative fractional resurfacing to radiofrequency micrnoeedling for facial acne scars in all skin types
Quantify and compare the effectiveness of nonablative fractional laser (Fraxel re:store, Solta Medical, Bothell, WA) alone to nonablative fractional laser alternating with microneedling with radiofrequency (Intracel, Perigee Medical, Redwood City, CA) for the treatment of atrophic, facial acne scars in all skin types.

This will be alternated with radiofrequency microneedling treatment will include 3 passes each at a depth of 2 mm, 1.5 mm, and 0.8 mm, treatment level 5 (32 w, 50 ms)-7 (40 w, 60 ms), monopolar setting with cold air cooling (Zimmer MedizinSystems, Irvine, CA) set on level 5. To be repeated for a total of 4 sessions (2 of each modality) at 4-week intervals.

Time frame: To be done right after treatments
Subjective change
Subjects will rate their perceived global change in acne scarring based on the subjected assessed global improvement scale.
Time frame: 3 months after final treatment
Subject satisfaction
Subjects will rate satisfaction on a 1-5 scale.
Time frame: 3 months after final treatment
Adverse events
