Background: Vaginal atrophy affects nearly of 50% of postmenopausal women. The study aimed to evaluate the use of intra vaginal light-emitting diodes after laser procedure for vaginal atrophy treatment, to minimize laser side effects. Methods: The study included 2 groups of treatment with 30 women in each. Group 1: one session of laser alone; Group 2: one session of laser, and immediately after, one session with Floreo® LED. Patients were followed-up for one month. Variables: distance urethra-vagina, thickness AA and AP, and vascularization. Results: At post-treatment, group 1 showed more signs of edema and inflammation. Differences were statistically significant for thickness AA (P=0.0014), thickness AP (P=0.0003), and vascularization (p<0.0001). One month post-treatment, both groups had similar anatomical values with no significant differences. Conclusion: Intra vaginal light-emitting diodes immediately after laser procedure, significantly minimized post laser treatment normal or expected transitory side effects, without diminishing its efficacy.
