Abstract
Infraorbital dark circles and tear trough deformity are considered common aesthetic problems. Numerous therapeutic modalities have been suggested with variable outcomes. The aim of this work wasto compare the efficacy of platelet‐poor plasma (PPP) gel versus platelet‐rich plasma (PRP) in infraorbital rejuvenation. A total of 68 females presented with dark circles and/or tear trough deformity were recruited and treated by PPP gel injection in the right infraorbital region (Group A) and PRP injection in the left infraorbital region (Group B). They received 3 treatment sessions at 2‐week interval, and followed up monthly for 3 months. They were evaluated clinically and dermoscopically before treatment and at the end of follow up period. Both groups showed significant clinical improvements proved by significant reduction of degree of hyperpigmentation and tear trough rating scale. Obviously, more significant clinical and dermoscopic improvements were observed in Group A than Group B.Therefore, it could be concluded that both PPP gel and PRP were clinically effective procedures for aesthetic improvement of infraorbital region. Moreover, PPP gel seems to be significantly more effective than PRP as a therapeutic modality.
