Comparative Study of Fractional CO2 Laser with and without Subcision for Facial Acne Scars

A 2026 study by Richin Anna Johnson compares the efficacy of fractional carbon dioxide laser treatment with and without subcision for facial atrophic acne scars. The research involved 30 patients aged 18–40 years, assessed using Goodman and Baron’s grading system and a patient satisfaction survey. Results indicate statistically significant better scar improvement and higher patient satisfaction in the group receiving combined laser and subcision treatment.

Use Cases

• Compare treatment efficacy based on patient-reported satisfaction scores.
• Analyze scar improvement outcomes using a quantitative and qualitative grading system.
• Study the impact of combining subcision with fractional CO2 laser therapy.

Strengths

• Study includes 30 patient records.
• Uses a standardized quantitative and qualitative acne scar grading system (Goodman and Baron).
• Includes patient feedback via a 5-point Likert scale.

Limitations

• Dataset is a single PDF document (944.3 KB), limiting machine-readability and direct analysis.
• Row count and column-level documentation are unknown.
• Data may reflect bias inherent to a single tertiary hospital's patient population.
