Unfortunately, there is no cure for this, and a series of more co2 lasering with dermapen would be my suggestion. You may need more aggressive treatment, to get a better result. Another consutlation is what is needed with someone who specializes in scar treatment. Remember, you can only improve the appearance not rid the scars completely. A relatively new treatment, Elos plus which is fractional radiofrequency has been excellent in my hands for situations like this and could be an option for you as well. We would gladly see you in the office anytime. I wish you the best of luck, Dr. Emer.
