The ex vivo photothermal experiments were conducted to assess the thermal effects on tissue integrity as a preliminary evaluation of safety. Human umbilical vein endothelial cells (HUVECs) were used as the experimental cell model to evaluate the in vitro effects of ICG-HA hydrogel under different therapies. A rabbit ear scar model (<em>n</em> = 36) was established and randomly divided into 6 groups: ICG-HA hydrogels + single-pulse irradiation, single-pulse irradiation, ICG-HA hydrogels + continuous-pulse irradiation, continuous-pulse irradiation, ICG-HA hydrogels and control (<em>n</em> = 6/group). Scar characteristics were monitored at 0, 1, 3, and 5 weeks using Ultrasound Doppler, colorimetry, VSS, and SEI assessments.

The similar trends were observed in the SEI scores.
