Acne Scars

Acne scar treatment has improved dramatically over the past two decades. Improvements in lasers allow for more predictable and better results. Fillers have also come a long way in terms of effectiveness and longevity.

Some patients require lasers. Others will benefit more from fillers. More commonly, patients with acne scars will benefit from a combination of both. While Dr. Rosenbach determines laser settings based on each individual patient, he and our providers conduct examinations and create customized treatments for each individual patient.


Our office uses two distinct lasers for acne scar treatments, depending on the shape, size, and color of the scar. For red scars in particular, our V-Beam Pulsed Dye Laser is used. These treatments, conducted by our clinicians, are performed once or twice each month for several months, usually requiring less than ten minutes with little to no downtime.

Besides the V-Beam, the fractional CO2 laser is also quite effective for treating acne scars. Decades of research have shown that various versions of this laser are known to smooth out indented scars by causing growth of underlying collagen. Fractional CO2 laser treatments for indented scars are spaced a few months apart, typically for 3-6 sessions.


For some types of depressed acne scars, Dr. Rosenbach uses fillers such as Restylane or Juvederm. Several groundbreaking medical publications within the past five years have revealed that fillers can be injected into acne scars to offer long term results. Dr. Rosenbach was one of the first providers in the United States to employ a new filler injection technique called the Tower Technique, which assists in achieving these long term results.

Whether by fillers, lasers, or a combination of both, acne scars are getting better results than ever. Everyone with acne scars is unique, which means a customized treatment plan will be designed for each patient.
