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.
