Platelet-Rich Plasma
Pronunciation: PLAYT-let rich PLAZ-muh
Also written as: PRP — Platelet-Rich Plasma
An autologous blood-derived preparation concentrated in growth factor–releasing platelets, used in cosmetic dermatology to promote skin rejuvenation and hair restoration.
Full Definition
Platelet-rich plasma (PRP) is produced by centrifuging a patient's own blood to separate and concentrate the platelet fraction, which contains growth factors such as PDGF, VEGF, and TGF-β. When injected or applied to the skin, PRP stimulates collagen synthesis, angiogenesis, and tissue repair. In cosmetic dermatology, it is used for facial rejuvenation, scar treatment, and androgenetic alopecia. The colloquial name 'vampire facial' refers to the combination of PRP with microneedling. Editors should use the abbreviation 'PRP' only after first full use, hyphenate 'platelet-rich' as a compound modifier before a noun, and avoid the sensationalised trade term 'vampire facial' in formal clinical documents.
Usage
Usage note: Hyphenate 'platelet-rich' when used as a compound modifier: 'platelet-rich plasma'. Expand PRP on first use. Avoid colloquial terms like 'vampire facial' in formal and regulatory copy.
