For unique cases where a variety of modalities could be used to treat the condition, I would suggest an in person or virtual consultation to develop a custom and effective treatment plan. It is difficult to precisely define the best option without collecting the same information. I suggest...
The Aerolase Neo would be a great option for hypertrophic scar treatment, especially scars with increased pigment (red in this photo). The Aerolase Neo is approved for treatment on all skin types and for scars such as the one noted in your photo, a series of treatments would be necessary.
No, the Aerolase laser is so gentle that it does not affect fillers in the face. If one is highly concerned, please do the laser treatment first and then follow it with a filler injection.
Sincerely,
Dr. Andrew K. Choi
