This study found that combining ultrapulsed fractional CO2 laser with bovine basic fibroblast growth factor significantly improved acne scars more effectively and safely compared to laser therapy alone.

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.

This study found that both 5-ALA and Photofrin can effectively destroy human microvascular endothelial cells in vitro and cause tissue necrosis in vivo, with Photofrin showing greater efficacy at lower concentrations or power densities.

This article shares the authors' experiences with the erbium YAG laser in hair restoration surgery, noting improved graft yield and reduced thermal damage compared to traditional methods.

This article discusses timed exposure settings with ablative lasers for treating benign dermal tumors and highlights their potential to reduce treatment time and scarring risk, but it reports no new clinical results.
