Additional comment from Contemporary OB/GYN Editorial Board Member John O. DeLancey, MD:
The long-term safety and efficacy of these treatments needs to be evaluated. The increase in vascularity that has been shown in short-term studies is likely part of an injury-repair phenomenon similar to what happens with healing incisions.
Just as an incision looks red for the first several months but turns white and avascular over time, it is possible that the increased vascularity produced by the laser could transform into devascularized scar later.
If this scarring develops once the original injury repair is completed, irreversible scarring could take its place. Proof that this does not occur is needed.
