Unfortunately, I am not surprised by the lack of success with the prior treatments. From the photo, the predominant issues are deep ice pick scars and dilated pores. TCA CROSS, which I have been performing for over twenty-three years, is my treatment of choice, in all skin types, for ice pick scars and dilated pores because the acid goes deep down the shafts of these scars and pores and closes them off as part of the healing process. By contrast, ablative therapies, like C)2 laser and dermabrasion, although aggressive on the surface do not get down to the depth of the scars. Following TCA CROSS, professionally performed manual microneedling (no need for the added risks and expense of RF micronreedling) can be sued to improve and blend better with the surrounding normal skin any residual surface, textural irregularities. You would be wise to consult an experienced, board certified cosmetic dermatologist scar treatment specialist. Best of luck.
