Dermal thickness in the 1st week of post-laser application

In the 1st week after laser and salicylic acid peel application, the dermis is thicker in the combined treatment group (A, C, E) than in the laser alone group (B, D, F). In addition, compared with the 3-pass C1 tip group (A, B), the 6-pass C1 tip (C, D) and 3-pass C5 tip (E, F) groups reveal a greater dermal thickness.

在激光及水杨酸换肤治疗后的第一周，联合治疗组（A、C、E组）的真皮层厚度相较于仅激光治疗组（B、D、F组）有所增加。此外，与三遍C1尖端组（A、B组）相比，六遍C1尖端组（C、D组）及三遍C5尖端组（E、F组）表现出更显著真皮增厚现象。该结果通过苏木精-伊红染色法获得，原始放大倍数为100倍，比例尺尺寸如图所示。
