Does Fraxel Work on Scars?

Fraxel 1550 "Restore" is my workhorse for most atrophic and/or discolored scars from acne, surgery, or trauma.  Occasionally I also use the 1927 also, making it a "Dual" treatment. For pitted scars, I pre-treat with TCA cross prior to doing the Fraxel. Acne scars usually need more than one session. Seek out a dermatologist who has experience with this excellent and versitile device.

First question is what type of scar you have.  Keloid scars - large overgrown thick red-brown scars - generally require injections of steroid and/or fluorouracil to soften and flatten before considering fraxel laser therapy.  At that point, some may be fine without laser, some may be helped with VBeam laser therapy and some may improve with Fraxel.  

Acne scars and white thin scars are commonly treated with Fraxel laser, either the Fraxel Repair carbon dioxide laser or Fraxel Dual in erbium mode.   Whichever laser is used, multiple treatments will be necessary usually at 4 - 6 week intervals.  You should start to see improvement about a month after the third treatment and then results will build from there.  Shallow rolling acne scars tend to respond faster than deeper icepick scars.

Another thing to remember about acne or other thin scars is that become more noticeable as your face loses volume.  So correcting volume depletion in your cheeks, temples, chin and jawlines is helpful.

I hope this answer was helpful. Best wishes.
