Association of Photobiomodulation With Platelet Rich Plasma Intradermal Injection for Facial Rejuvenation

Summary

Skin aging is an irreversible, slow and progressive process. It is influenced mainly by age, but also by external factors such as ultraviolet radiation, smoking, alcohol, among others. It is increasingly common to look for procedures that slow this process by limiting or hiding its effects on the skin and its appearance. Intradermal platelet-rich plasma (PRP) injection is a new modality of treatment which has possible beneficial effects on skin rejuvenation. In addition, studies have shown photobiomodulation (PBM) benefits to the skin. The purpose of this paper is to investigate the effects of combined use of intradermal PRP injection on the face and photobiomodulation for facial rejuvenation. To this end, a randomized, double-blind, controlled clinical trial will be conducted with volunteer participants who wish to improve facial aesthetics, attended at the Nove de Julho University specialty medical outpatient clinic in the city of São Paulo. Participants will be divided into three groups: one group will undergo intradermal application of PRP in association with PBM; another group will undergo intradermal application of PRP and placebo light and a third group will receive intradermal application of 0.9% saline solution (placebo) associated with PBM. Only one application of PRP or saline solution will be performed at defined points on the face. PBM sessions will be held immediately after the first application of PRP or saline solution, 3 days after the first application and weekly for the next 3 weeks. The following variables will be studied for further analysis: face moldings analyzed by optical coherence tomography; skin viscoelasticity; histological study of the dermis; evolutionary comparison of photographic images by plastic surgeons (Wrinkle Assessment Scale) and participants' satisfaction level (FACE-Q). All data will be statistically evaluated according to their distribution.

Interventions

PROCEDURE

PRP application

The study participant will receive topical anesthesia with lidocaine ointment (50mg/g). After 5 minutes the face will be cleaned with 0.5% alcohol chlorhexidine solution. The newly obtained platelet-rich plasma activated with 10% calcium chloride packed in a 5mL syringe will be applied to the face using a 30G needle in the frontal, lateral periorbital, nasogenian sulcus, bilateral malar region and an infra-auricular point. 0.1ml per cm2 will be injected, totaling 43 points. Only one application of PRP will be performed at the defined points.

OTHER

Placebo PRP application

Blood collection will be performed normally, the time between collection and application of saline will be the same as the PRP protocol, but in this case, the blood will be discarded, only a sample to quantify the number of platelets will be sent for analysis.

RADIATION

Photobiomodulation

Photobiomodulation will be applied with a Cosmedical LED face mask (São Paulo, Brazil) containing 92 red LEDs. The applications will occur in the experimental periods of 0, 3, 7, 14, 21 and 28 days after the application of PRP or placebo.

OTHER

Placebo Photobiomodulation

Participants will not be aware of whether or not they have received the PBM application as they will be using eye protection and the researcher will position the equipment at the irradiation locations on all participants. The characteristic sound of the device will be triggered by recording in the placebos groups for the PBM. The placebo applications will occur in the experimental periods of 0, 3, 7, 14, 21 and 28 days after the application of PRP.
