A PFR injection refers to two distinct applications, depending on the context:
1. Platelet-Rich Fibrin (PRF) Injections in Dermatology
In dermatology, a PFR injection, more accurately referred to as a PRF injection, is a type of filler treatment. It uses a portion of your own blood to enhance appearance. This differs from PRP (Platelet-Rich Plasma) injections in that it has a higher concentration of platelets, fibrin, and white blood cells, along with a small amount of stem cells. PRF injections are used to treat various concerns, including:
- Dark under-eye circles
- Wrinkles
- Sagging cheeks
The body's own platelets and growth factors are isolated and used to improve the appearance of a specific area. [Source: Byrdie, Glamour]
2. PFR Diesel Injection Pumps in Automotive Engineering
In automotive engineering, PFR refers to a type of diesel injection pump manufactured by various companies, including Bosch, Denso, and Zexel. These pumps are often found in Kubota engines and other applications. The PFR designation represents a specific model or series of pumps characterized by their design and functionality. Common issues include leaks, requiring repair or replacement of components such as O-rings, plungers, and barrels.

Specific model numbers often include variations like PFR..KX, PFR..KD, and PFR..MD, indicating different configurations. [Source: Injection Power]
