BACKGROUND: The 2,940 nm erbium-doped yttrium aluminium garnet and 1,064 nm neodymium-doped yttrium aluminium garnet lasers have been widely applied in facial rejuvenation, but no randomized trials exist to evaluate the efficacy of the combination treatment. OBJECTIVE: The efficacy of the combined treatment for facial rejuvenation. MATERIALS AND METHODS: A total of 20 subjects with facial aging were enrolled and randomly assigned into 2 groups: one side of the face was treated with a 2,940 nm or 1,064 nm laser alone and the other side was treated with the combined lasers. The patients were treated by 3 sessions with 1-month intervals. The efficacies were quantitatively accessed by digitalized high-resolution photographs. RESULTS: The 1,064 nm laser alone showed significant improvements on indexes of skin texture, spore, brown spots, elasticity, and melanin as compared with the baseline (p < .05). The 2,940 nm laser alone showed significant improvements on indexes of wrinkle, texture, pore, and elasticity (p < .05). The combined treatments showed significant improvements on the abovementioned indexes as compared with either a 1,064 nm or 2,940 nm laser treatment (p < .05). CONCLUSION: A combination of 1,064 nm and 2,940 nm laser treatment renders significantly better efficacies for facial rejuvenation as compared with a 2,940 nm or 1,064 nm laser alone.
