A Retrospective Analysis of the Effectiveness of Fractional CO₂ Laser Therapy in Treating Linear Scars: Investigating the Ideal Timing for Intervention.

Background: Linear scars, resulting from surgical incisions or traumatic injuries, can pose both aesthetic and functional dilemmas. Ablative fractional CO₂ laser (AFCL) therapy has been recognized for its ability to enhance the appearance and flexibility of scars; however, the ideal timing for such treatments remains a subject of debate.

Aims: This study retrospectively evaluates the effectiveness of AFCL in treating linear atrophic and hypertrophic scars, with a focus on identifying the optimal timing to achieve the best possible outcomes.
