Fraxel Laser is amazing for scars
I wish you had submitted a photo to see the scars you are describing. No matter what laser you have done, the Fraxel laser is a superior laser for scars in reducing the depth and degree of scars. The 1550 nm setting is specifically designed for scars/wrinkles in a gentler way giving you only two days of swelling and redness. I would definitely find a board certified dermatologist with experience in Fraxel for a consultation.
