Objective: Evaluation of the efficacy and side effects of neodymium-doped yttrium aluminum garnet (Nd:YAG) laser and Nd:YAG laser–intense pulsed light (IPL) combination treatments in photorejuvenations of skin of the hand, and determining their impacts on patient satisfaction. Materials and Methods: Thirty-five female patients with signs of photoaging on the skin of their hands were included in the study. Three sessions of IPL and four sessions of Nd:YAG laser treatment were applied to the right hand in total with 2-week intervals between each session, whereas six sessions of Nd:YAG laser treatment were applied to the left hand of patients with 2-week intervals between each session. Results: The patients' ages ranged between 31 and 78, and mean age was 60.77 ± 9.48. While there was no difference in pigment distribution, fine wrinkles, coarse wrinkles, and global scores between the right and left hand prior to treatment (p > 0.05), average pigment tone score was higher in the right hand with a statistically significant difference (p < 0.05). There was greater improvement in scores of pigment distribution, fine wrinkles, sallowness, pigment tone parameters, and global score on the right hand compared to left hand, which was statistically significant (p <0.001). Conclusion: In rejuvenation of photoaged dorsal skin of the hand, IPL–Nd:YAG laser combination treatment surpasses Nd:YAG laser treatment. [ABSTRACT FROM AUTHOR]
