Abstract
Background: Aging of the skin consists of a combination of genetically predisposed factors (intrinsic aging) and environmental factors (photo aging). The resulting clinical manifestations include mottled pigmentation, wrinkles, and change of the superficial texture leading to coarseness of the skin Dermal components such as collagen and elastic fibers gradually decrease, skin loses its elasticity and shows wrinkles. Loss of skin moisture and subcutaneous fat accelerates the process.
Objective: To evaluate the efficacy, possible side effects, durability and study of platelet rich plasma injection versus Plasma gel injection in periorbital rejuvenation.
Methods: This comparative split face study included 40 females with periorbital wrinkles and/or dark circles recruited from the Dermatology outpatient clinic of Ain-Shams University Hospitals.Right periorbital wrinkles was injected by platelet rich plasma while left periorbital side was injected by plasma gel.
Results: Treatment with plasma gel resulted in significant improvement of periorbital wrinkles with minimal complications compared to platelet rich plasma. While, dark haloes and skin texture were minimally affected whether with plasma gel or PRP injection.
Conclusion: Plasma gel as well as platelet rich plasma injections may play role in treatment of periorbital wrinkles but mostly for short durations. Plasma gel injection is more effective in periorbital rejuvenation than PRP injection although it has relatively higher complications rate. Both plasma gel and PRP injections has only minimal role in treatment of periorbital dark hallows.
