Platelet-rich plasma is a procedure that concentrates platelets from a person's own blood and returns them into facial skin, used for wrinkles, rough texture and acne scars. Its clearest value is as an add-on: it improves depressed acne scars and shortens recovery after laser treatment. Alone, results for aging skin are mixed. Common side effects are brief redness and bruising; rare serious harms depend on who performs it and how. (Full Review)
| Marker | Target | Why |
|---|---|---|
| Platelet count | 200–350 ×10³/µL | Sets concentrate strength |
| Hemoglobin | Women 13.5–15.0 g/dL; men 14.5–16.5 g/dL | Screens for anemia |
| Ferritin | 50–150 ng/mL | Iron reserve for repeated draws |
| Concentrate platelet level | 3–6 times own blood level | Confirms delivered dose |
| INR (warfarin users only) | 2.0–3.0 per prescriber target | Bleeding risk |
| HbA1c | Below 5.4% | Healing capacity |
| Standardized facial photographs | No established target; track change from own baseline | Objective outcome |
Cadence: Baseline before the first session; photographs and self-ratings at each session, 1 month after the third session, then every 6 months during maintenance; complete blood count annually on maintenance draws, or sooner if bruising, fatigue or medication changes suggest a problem
