Impact of dual wavelength laser therapies in the treatment of hypertrophic scars and keloids: a systematic review
Bibliographic record
Abstract
Common skin diseases arising from improper wound healing, hypertrophic scars and keloids, may have a substantial influence on patients' quality of life. They are characterized by elevated, hard scars with varied color. The purpose of this narrative review is to evaluate the safety and efficacy of dual-wavelength laser therapy for the treatment of keloids and hypertrophic scars. A thorough literature analysis was carried out, including research from reputable sources like Google Scholar and PubMed. The review examined the mechanisms of action, safety profiles, and clinical results of dual-wavelength laser systems. Dual-wavelength lasers show notable changes in texture and elasticity as well as a considerable decrease in scar visibility. PDL (585–595) and Nd lasers (1064 nm) work well together to target deeper dermis layers as well as superficial vascularity. Clinical tests show significant improvements in skin texture and tone as well as a 40% decrease in scar scores. For example, the dual-wavelength technique led to significant improvements in patient satisfaction and reductions in Vancouver Scar Scale ratings. Positive safety profiles include mild and temporary side effects including pain and erythema. When treating complicated scars, the dual-wavelength approach consistently works better than single-wavelength lasers. Dual-wavelength laser treatments provide a complete and successful management strategy for keloids and hypertrophic scars. Although the results are encouraging, further studies using standardized methods and longer follow-up periods are required to confirm these outcomes and improve treatment plans.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
