Microfocused ultrasound is a non-invasive technology widely used for its ability to stimulate collagen production, generate fat lipolysis and provide lifting. Despite its benefits, many patients avoid the procedure due to the associated pain and discomfort. The aim of this study was to quantitatively evaluate the pain perceived during the application of HIPRO microfocused ultrasound to the lower eyelids and sides of the eyes, using the numerical pain scale (NRS). The sample consisted of 10 individuals aged between 30 and 50. The methodology included the application of HIPRO at a frequency of 10Hz and a depth of 1.5mm, with 900 shots per treated area. Pain was measured after 450 and 900 shots. The results showed that the majority of patients rated their pain as mild or non-existent, with an average score of 1.175 out of 10 on the NRS. The variability in pain perception reinforces the importance of personalized approaches. Compared to other devices, HIPRO proved to be an effective and relatively comfortable alternative, especially for pain-sensitive patients. It is concluded that HIPRO microfocused ultrasound is a safe and effective option for facial rejuvenation, with a manageable discomfort profile and good clinical results.
