Abstract
Early intervention for scars is a vital focus in dermatologic surgery, with various treatment options showing potential in enhancing the appearance and texture of scars. This randomized controlled study evaluated the effectiveness of fractional CO₂ laser treatment compared to hyaluronidase injection in managing early scars. Sixty patients with recent scars were randomly assigned to receive either fractional CO₂ laser treatment (n = 30) or hyaluronidase injection (n = 30), with 56 patients completing the study. Treatments were conducted over 4-6 sessions, followed by a 6-month follow-up. The CO₂ laser group showed significantly better results, achieving a 45.3% reduction in scar volume compared to 32.7% in the hyaluronidase group (p < 0.001). Improvements in the Vancouver Scar Scale were also significantly higher in the CO₂ laser group (52.4% ± 15.6% vs. 38.9% ± 14.2%, p < 0.01). Histopathological analysis indicated better collagen organization, improved elastic fiber networks, and lower type I/III collagen ratios in the CO₂ laser group, nearing values typical of normal skin. Both treatments had favorable safety profiles, but the CO₂ laser group needed fewer treatment sessions. These results provide strong evidence that fractional CO₂ laser is a preferred option for early scar management, especially when treatment begins in the third week after scar formation.

Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
