A treatment that concentrates platelets from a person's own blood and returns them to the skin to rebuild collagen. Safety is favorable, with mostly short-lived redness and bruising; the worst harms trace to unlicensed handling of blood. Benefits are modest and mixed, strongest for skin texture, smoothness, and the under-eye area. (Full Review)
| Marker | Target | Why |
|---|---|---|
| Platelet count | ~200–400 ×10⁹/L | Determines quality of the PRP concentrate |
| Hemoglobin | ~13–15 g/dL (women ~12.5–15) | Flags anemia that impairs healing and product quality |
| Ferritin | ~50–150 ng/mL | Low iron impairs skin and tissue repair and may signal anemia |
| HbA1c | ≤5.4% | Poor glucose control slows wound healing and collagen formation |
| Vitamin D (25-OH) | ~40–60 ng/mL | Supports skin repair and immune function |
| hs-CRP | <1.0 mg/L | High systemic inflammation may impair healing response |
Cadence: Baseline before starting; reassess at end of induction series (~8–12 weeks), then at each maintenance visit every 6–12 months
