Background Keratosis pilaris is a common keratinization disorder of the extensor surfaces of the proximal extremities. Various treatment modalities reduce symptoms, but their efficacy is limited. Aims The aim of this study is to compare the efficiency of Q-Switched Nd: YAG laser and fractional Er: YAG laser. Material/Method The lesions in both arms were randomly divided into areas A and B. Fractional Er: YAG 2940 nm laser performed to area A 1.5 J/cm(2), spot size 7 mm, frequency 3 Hz and three passes and Q-Switched Nd: YAG 1064 nm laser performed to Area B, 4-6 J/cm(2) spot size 4 mm, 8 Hz frequency, and as a single pass. Both lasers were performed in 4 sessions at 3-week intervals. The global improvement scale evaluated treatment responses in dyspigmentation and skin texture. Results Twenty patients completed the study, and the mean age of a total of 20 patients was 22.9. There was no significant difference in dyspigmentation and skin texture with global improvement scale between Area A and Area B, respectively (p = 0.078, p = 0.638). In addition, there was no significant difference between patient satisfaction levels after treatment in Area A and Area B (p = 0.868). Conclusion The efficiency of the fractional Er: YAG 2940 nm laser was found equal to the Q-switched Nd: YAG 1064 nm laser. Fractional Er: YAG 2940 nm laser may be a new treatment option in the treatment of keratosis pilaris.
