ABSTRACT

BACKGROUND:

Platelet-rich plasma (PRP) is an autologous concentration of human platelets contained in a small volume of plasma and has recently been shown to accelerate rejuvenate aging skin by various growth factors and cell adhesion molecules.

OBJECTIVE:

This study was conducted to evaluate the efficacy and safety of intradermal injection of PRP in the human facial rejuvenation.

METHODS:

This study was a prospective, single-center, single-dose, open-label, non-randomized controlled clinical study. PRP injected to the upper site of this right infra-auricular area and all face. Saline was injected to the left infra-auricular area. Histopathological examinations were performed before PRP treatment, 28 days after the PRP, and saline (control) treatments.

RESULTS:

Twenty women ranging in age from 40 to 49 years (mean age, 43.65±2.43 years) were enrolled in the study. The mean optical densities (MODs) of collagen in the pre-treatment, control, and PRP-treated area were measured. They were 539±93.2, 787±134.15, 1,019±178, respectively. In the MOD of PRP, 89.05 percent improvement was found when MOD of PRP was compared with MOD of pre-treatment. The mean MOD of collagen fibers was clearly highest on the PRP side (p<0.001). The PRP-to-saline improvement ratio (89.05% to 46.01%) was 1.931. No serious side effects were detected.

CONCLUSION:

PRP increases dermal collagen levels not only by growth factors, but also by skin needling (the mesotherapy technique 'point by point'). PRP application could be considered as an effective (even a single application) and safety procedure for facial skin rejuvenation.
