Evaluating the Efficacy of Combined Platelet-Rich Plasma and Microneedling for Aesthetic Rejuvenation of the Periorbital Area: A Randomized, Blinded Cohort Study

Microneedling, a technique involving controlled dermal microwounding, and platelet-rich plasma (PRP) injections are both employed for skin rejuvenation. While both treatments individually show promise, limited research has explored their combined efficacy. This study aimed to evaluate the effectiveness of combining PRP injections with microneedling for aesthetic concerns around the eyes under standardized conditions. This single-center, longitudinal cohort study was conducted from October 2017 to October 2020. Thirteen adult participants (mean age 35, 92.3% female) with aesthetic concerns in the periorbital area underwent combined PRP and microneedling treatment. Standardized photographs were taken preprocedure, at 1 week, and 3 months. Photographs were evaluated by three blinded dermatologists using validated photonumeric scales. Participants completed a self-assessment questionnaire at the 1-week follow-up regarding skin homogeneity, texture, pigmentation, and wrinkles. Self-reported outcomes indicated perceived improvements in skin homogeneity (72.7% reporting mild or significant improvement) and texture (81.8% reporting mild, moderate, or significant improvement). Improvements in pigmentation and wrinkles were less pronounced. Dermatologists' assessments revealed no significant differences in skin attributes before and after treatment. Despite subjective reports of improvement, objective evaluations by independent dermatologists did not demonstrate significant changes. Variability in outcomes might be attributed to differences in study design, treatment protocols, and assessment methods. Further research with larger sample sizes and multiple treatment sessions is needed to better understand the benefits of combining PRP with microneedling for periorbital rejuvenation.
