I have moderate acne scarring and some premature aging. I grew up eating a very bad diet (latch key kid). All sugar and carbs. I have had forehead wrinkles since 15yrs old. I also had very severe cystic acne. I went on accutane at 26. I am 31 now. I eat and live very healthy now. Why don't collagen inducing treatments work on me? I've tried fully ablative c02, microneedling, daily peels, retin a. My skin looks slack and worse. I respond very well to filler. Is there a test I can do?
