Dispatch from ASLMS: Combining Fractional Ablative & Non-Ablative

Dr. Lawrence Bass, Director of Minimally Invasive Plastic Surgery at NYU Medical Center reported the results with simultaneous fractional non-ablative (1540 nm) and fractional ablative (fractional erbium, 2940 nm) laser therapy.

The percentage of skin covered in a single treatment was increased from 20-30% in a typical fractional erbium treatment to over 60%. Healing time increased by about 1 day (average 4-5 days). Despite this modest change in healing times, 86% of patients experienced at least a 50% improvement in wrinkle severity when graded by blinded doctors examining before and after photos at 3 months. 36% experienced a 75% or better improvement.

Skin tightening was also seen but this is the subject of ongoing study. This study demonstrated that wrinkle clearance similar to that seen with old-fashioned ablative laser resurfacing can be obtained, more consistently that what either stand-alone fractional treatment can produce.

  1. I looked at Dr. Bass' site, and couldn't find any information on this study. Do you know which devices he was using?

  2. he was using the palomar system although most likely similar results would be seen with similar non-ablative and ablative technology.
