Fraxel Failed to Work on my Acne Scars

I am not surprised that you didn't receive benefit in acne scarring with Fraxel Refine. This laser was developed for the spas and not for physician treatment, therefore it is not expected to penetrate deep enough to affect acne scars. Multiple Fraxel Restore treatments often provide my patients with better acne treatment results than the old fashioned carbon dioxide laser treatment.  Fraxel Repair is the most aggressive laser and it can help acne scars also. See a laser specialist who has a significant experience in the treatment of different types of acne scars.

Dr. Schlessinger has hit it on the head.
Fraxel (any generation) is great for fine wrinkles. Deep acne scars are more challenging. The key is improvement. Some ablative laser techniques can improve even deep acne scars but be prepared for significant downtime (think weeks at home with a hoodie and sunglasses).
The same applies for chemical peels and dermabrasion. Unfortunately scars are one of the most challenging things we face.
Be careful of marketing promises and be sure to consult a board certified Dermatologist, facial plastic surgeon or plastic surgeon.
I hope this helps.

Acne scars cannot be eliminated by any means. They can only be improved, regardless of the type of treatment. This discussion should take place with any consultation of acne scars. The improvement of acne scars can be qualitative and quantitative but is never predictable.
Fraxel laser works by subjecting the skin surface to pixelated beams of laser light. The depth of treatment is within the dermis and the amount of skin surface treated at any given time is less than 25%. Thus, four or five treatments can theoretically treat the whole skin surface.
Acne scars can be improved with Fraxel laser. Chemical peels and acne surgery can also improve the quality of acne scars on the face.
Discuss the nature and depth of your acne scars and more importantly, the quality of the surrounding skin with your doctor so as to form a practical goal for treatment.
