January 2023 in “Biomedicines” This study found that using a combination of ablative CO₂ fractional laser and fetal fibroblast transplantation significantly reduced scarring in mice, with long-term sphere-forming cultured fibroblasts producing scar appearances closest to normal skin.
October 2025 in “Iraqi postgraduate medical journal” This study observed that using fractional CO2 laser-assisted delivery of clobetasol propionate cream significantly improved treatment outcomes for localized alopecia areata compared to the cream alone, suggesting the laser's enhancing effect on hair regrowth.
January 2025 in “Dermatologic Therapy” This study found that ablative fractional carbon dioxide laser treatment improved skin fibrosis, reduced skin hardening, and enhanced hair follicle growth in localized scleroderma patients, with significant improvements across several clinical measures and no severe adverse effects observed.
