Facial rejuvenation by microneedling with irradiated amniotic collagen matrix compared to platelet rich plasma

Many modalities are used for treatment of facial wrinkles, such as microneedling that enhances collagen production, and platelet-rich plasma (PRP) which contains concentrated levels of growth factors. The human amniotic membrane isolated from the placentae of donors (during elective cesarean sections) has high levels of growth factors that help in rejuvenation by improving the migration and proliferation of keratinocytes, fibroblasts and increased collagen synthesis. Was to confirm the efficacy of irradiated amniotic collagen matrix (IACM) versus platelet rich plasma (PRP) delivered via microneedling in facial rejuvenation. The present study included 20 patients with facial wrinkles divided into two groups using split face technique: Group A subjected to microneedling with topical IACM on the right side of the face. Group B subjected to microneedling with topical PRP on the left side of the face. Patients received six sessions 2 weeks apart. Photos by Antera camera and skin biopsies were taken to assess the clinical results. There were a statistically significant improvement in both sides after than before treatment; with better improvement in patients treated with IACM more than patients treated with PRP using microneedling in both sides as proved clinically (assessed by WSRS and GAIS scale), pathologically (Orcein and Masson trichrome stain) and by Antera camera (texture and pigmentation). Microneedling using IACM is a new, safe and effective method for facial rejuvenation, more effective when compared to microneedling using PRP; in need for further studies to evaluate the correct dose and number of sessions to get the best outcome.
