research Synergistic Effects of Fractional CO 2 Laser and Recombinant Humanized Type III Collagen (rhCol III) in Atrophic Acne Scar Treatment: Activation of MAPK Pathway and Enhanced Collagen Remodeling
In this study, treatment with fractional CO2 laser combined with recombinant humanized type III collagen led to significantly better improvements in atrophic acne scars compared to laser treatment with saline, attributed to collagen upregulation and MAPK pathway activation in human dermal fibroblasts.
