I had a horrible experience with injectables which left raised lines. Will Fraxel laser help flatten these lines?

Fraxel is a great laser for the fine lines and wrinkles.  I am unclear why you have scars from injectables.  What kind of filler did you have? Why was there scarring? Fraxel is the gold standard for treating scars with minimal down time.  I hope that you consult a dermatologist with a great deal of experience with scars and lasers.  Please keep me posted.
