Efficacy of Erbium-Doped Yttrium Aluminium Garnet 2,940 and 1,064 nm Laser Treatment for Facial Rejuvenation—A Randomized Controlled Split-Face Clinical Trial

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
