Clinical evaluation of combined autologous Platelet-Rich Plasma and Volume-Controlled Ozone Therapy in Facial Rejuvenation: A randomized controlled Pilot Study.

Platelet rich plasma and ozone therapy have been suggested in the clinical setting as promising and adjuvant therapies for managing the symptoms related to the facial aging. However, there is a lack of evidence about the effects of combining both therapies on rejuvenation. Thus, the aim of the present study was to evaluate and to compare the safety and efficacy of both therapies in facial aging. A single-center prospective pilot study was conducted. Female participants, aged 40 to 60 years, were randomized into 2 groups: participants received the platelet rich plasma treatment (PRP); participants received the therapy with platelet rich plasma associated with ozone therapy (PRPOT). Interventions were performed using the facial intradermal technique in 42 pre-established points, for 4 sessions with an interval of 15 days between them. After analyses performed using photographic records, assessment of frontal, periorbital, nasolabial and marionette wrinkles (Wrinkle Assessment Scale), self-esteem assessment (Brazilian Version of Rosenberg's Self-Esteem Scale) and assessment of patient satisfaction (FACE-Q) can be suggested that the platelet rich plasma protocol performed in the present study, as well as its association with volume-controlled ozone therapy, proved to be safe and potentially promising modalities in the treatment of facial aging.
