As acne scars remain challenging to treat, this study compared the safety and efficacy of two laser modalities for acne scar treatment. Between 2022 and 2024, 88 patients were treated for acne scars using either the Hybrid platform with the ProScan applicator, which delivers fractional ablative carbon dioxide (CO
2) 10,600 nm and non-ablative 1570 nm wavelengths in a dual mode, or the Pixel CO
2 laser with the LiteScan applicator, which delivers a fractional ablative CO
2 10,600 nm wavelength alone. Clinical efficacy was assessed using the Echelle d’Evaluation Clinique des Cicatrices D’Acne (ECCA) scale. Both groups showed significant improvements in ECCA scores post-treatment (
p < 0.001, Wilcoxon signed-rank test). However, the percentage change in scores from baseline to post-treatment did not differ significantly between the groups (
p > 0.05, Wilcoxon rank-sum test). Adverse effects were mild and transient, resolving within a few days, with no significant differences between the groups (
p > 0.05, chi-squared test). Both laser modalities demonstrated high efficacy and safety in treating acne scars, with significant post-treatment improvement in scar severity.
