What Is It?
Non-ablative lasers are less invasive but also less effective than ablative lasers. Non-ablative fractional lasers shine a focused beam of light at the skin in a fractional (dot-matrix) pattern, leaving the skin intact.
Good or Excellent Response
Strength of Evidence
12% of patients achieved a good (>50%) or excellent (>75%) improvement in scarring after 3 - 6 sessions
Strength of Evidence
60% of patients achieved at least a moderate (>25%) improvement in scarring after 3 - 6 sessions
