ABSTRACT
Introdução: Essa revisão sistemática foi conduzida para avaliar se a associação da aplicação da injeção de agregados plaquetários quando comparada a outras terapias faciais favorece no rejuvenescimento facial em pacientes adultos. Métodos: A pesquisa buscou ensaios clínicos randomizados que compararam uso de técnicas de rejuvenescimento facial isoladas com as mesmas técnicas aliadas à injeção de agregados plaquetários. A busca foi realizada em bases de dados indexadas e literatura cinzenta. A ferramenta de risco de viés da "Cochrane Collaboration" foi aplicada para a avaliação da qualidade dos estudos. Resultados: Foram identificados 7137 artigos. Apenas quatro estudos permaneceram na síntese qualitativa, e os demais foram considerados com risco indefinido de viés nos domínios chaves. Conclusão: Existem poucos estudos na literatura que comparam o uso de agregados plaquetários em rejuvenescimento facial e os que estão disponíveis têm risco de viés "indefinido" ou "alto". Há necessidade de realizar mais estudos clínicos bem delineados que comparem o uso de injeção de agregados plaquetários associados ou não às técnicas de rejuvenescimento facial.
Introduction: This systematic review was conducted to assess whether the use of a platelet aggregate injection with or without associated facial rejuvenation techniques favors facial rejuvenation in adult patients. Methods: Randomized clinical trials that compared the use of techniques for facial rejuvenation alone with the same techniques coupled with the injection of platelet aggregates were searched. The search was performed in indexed databases and in the gray literature. The Cochrane Collaboration bias risk tool was applied to assess the quality of the studies. Results: In total, 7137 articles were identified. Only four studies remained in the qualitative synthesis, and the others were considered as having undefined bias risk in the key domains. Conclusion: There are few studies in the literature that compare the use of platelet aggregates in facial rejuvenation and those that are available have a risk of "undefined" or "high" bias. There is a need for more well-designed clinical studies comparing the use of platelet aggregate injection with or without associated facial rejuvenation techniques.

Fundamento: la bioestimulación facial con plasma rico en plaquetas es un método actual de rejuvenecimiento facial que entra dentro de las terapias regenerativas. Objetivo: mostrar el papel principal de la bioestimulación como método positivo en las características de la piel facial. Métodos: se realizó una revisión bibliográfica de un total de 140 artículos originales publicados en Pubmed, Medline, Scielo y Google académico en los idiomas inglés y español mediante el gestor de referencias bibliográficas Endnote x9, de ellos se utilizaron 48 citas seleccionadas para realizar la revisión. Desarrollo: el envejecimiento es un proceso muy complejo, donde el envejecimiento cutáneo es una de sus manifestaciones más evidentes, por lo que el cirujano plástico busca constantemente formas de lograr atenuar este proceso, una de estas alternativas es la infiltración facial con plasma rico en plaquetas. Se describe la técnica de procesamiento de la sangre para obtener el plasma rico en plaquetas y el método empleado para la bioestimulación facial. Indicaciones y contraindicaciones del proceder. Conclusiones: la bioestimulación facial con plasma rico en plaquetas es un método sencillo, libre de complicaciones dado que se trabaja con material autólogo, mediante el cual se logran cambios positivos en la piel.
Background: facial biostimulation with platelet-rich plasma is a modern method for facial rejuvenation that is part of the regeneration therapies. Objective: to show the main role of biostimulation as a positive method for the characteristics of facial skin. Methods: a bibliographic review of 140 original articles published in Pubmed, Medline, Scielo and academic Google in English and Spanish, was made by means of the reference management software Endnote x9. Forty-eight citations were selected to make the review. Development: aging is a complex process and skin aging is one of its clearest manifestations; that’s why, plastic surgeons are constantly looking for new ways to reduce this process. One of these alternatives is facial infiltration with platelet-rich plasma. The technique of processing blood to obtain platelets-rich plasma and the method used for facial biostimulation are described. Indications and contraindications of the procedure are also described. Conclusions: facial biostimulation with platelet-rich plasma is a simple, complications-free method since the procedure is made with an autologous by means of which positive changes in the skin are achieved.

La presente revisión fue realizada con el objetivo de ampliar los conocimientos sobre el envejecimiento cutáneo y los tratamientos restitutivos empleados en la cirugía plástica ocular, especialmente la bioestimulación cutánea con plasma rico en plaquetas, como alternativa novedosa de rejuvenecimiento periocular. Se realizó una búsqueda bibliográfica amplia y actualizada en bases de datos que ofrece Infomed, como Ebsco, Hinari, Pubmed, Google académico y textos básicos de Oftalmología y Cirugía Estética. El plasma rico en plaquetas es un preparado biológico efectivo para la bioestimulación cutánea; incrementa la producción de colágeno; elastina y ácido hialurónico, proporciona una piel con más brillo, mejor textura, hidratación y elasticidad; presenta múltiples ventajas y mínimas complicaciones, lo que contribuye a elevar la calidad de vida de los pacientes(AU)
The objective of this review was to expand knowledge on skin aging and restorative treatments used in ocular plastic surgery, especially cutaneous biostimulation with platelet-rich plasma, as a novel alternative of periocular rejuvenation. A comprehensive literature search was performed in updated databases that Infomed provides such as Ebsco, Hinari, Pubmed and Google and basic academic texts of cosmetic surgery and ophthalmology. The platelet-rich plasma is an effective biological preparation for skin biostimulation, increases the production of collagen, elastin and hyaluronic acid, and provides a brighter skin, improved texture, hydration and elasticity. It really has many advantages and minimal complications, thus contributing to raise the quality of life of patients(AU)

Platelet-rich plasma [PRP] is an autologous concentration of human platelets contained in a small volume of plasma characterized by haemostatic and tissue repairing effects. Tissue repairing effects and being enriched by various kind of growth factors, has made them the focus of attention for different procedures. PRP has been effective in bony defects, wound healing and recently for aesthetic procedures in plastic surgery. The purpose of this review is to evaluate and summarize the applications of PRP in the dermatology literature, with particular focus on rejuvenizaton process, advances and limitations of current PRP therapies. We studied literature related to PRP therapy, these include regeneration of soft tissue, skin aging mechanisms, as well as wound healing. Some studies have shown promising results, with favorable outcomes about PRP clinical application for skin rejuvenization. This article summarizes our current understanding regarding photoaging process and the role of PRP in the skin rejuvenization process. PRP has been shown to be useful in skin rejuvenization. Further studies are needed to elucidate both basic and clinical aspects of PRP therapies. In particular, platelet preparation methods, different application methods, platelet mechanism of action in rejuvenation field, interactions with the skin components, long-term efficacy and safety are necessary to be determined
