What is PRP Treatment? In modern medicine, more patients and doctors focus on using the body’s own resources to promote healing and restore function. PRP (Platelet-Rich Plasma) treatment represents a leading approach in regenerative medicine. Instead of relying on external drugs, doctors prepare PRP directly from a patient’s blood and then inject it back into specific areas to stimulate natural repair.
Doctors first applied PRP in sports medicine and orthopedics. Today, it plays a role in dermatology, aesthetics, dentistry, wound care, and even reproductive medicine. Its broad use shows strong potential as a safe and regenerative option. So how does PRP treatment actually work, and what benefits can it bring?
The Concept and Mechanism of PRP
PRP is a plasma preparation in which platelets reach three to five times their normal concentration.
Platelets do more than stop bleeding. They store and release many growth factors, such as:
- PDGF (Platelet-Derived Growth Factor): stimulates fibroblast growth and blood vessel formation.
- TGF-β (Transforming Growth Factor): promotes collagen production and improves tissue quality.
- VEGF (Vascular Endothelial Growth Factor): drives new blood vessel growth.
- EGF (Epidermal Growth Factor): supports skin cell regeneration.
- IGF (Insulin-Like Growth Factor): aids bone and tendon repair.
- Cytokines like IL-8 regulate inflammation.
When doctors inject PRP into damaged tissue, these bioactive factors create a microenvironment that encourages cells to repair and regenerate.
How Doctors Perform PRP Treatment
1. Blood Collection
The doctor draws a small amount of blood, usually between 10 and 60 ml, from the patient’s vein.
2. Centrifugation
The blood sample spins in a centrifuge, which separates the red cells and most plasma, leaving behind platelet-rich plasma.
3. Preparation and Activation
In some cases, the doctor adds calcium chloride or thrombin to trigger the platelets to release growth factors faster.
4. Injection or Application
The doctor then injects the prepared PRP into the target area—such as a joint, tendon, scalp, or facial skin—or applies it during surgery.
The entire process usually takes 30 to 60 minutes, and medical staff maintain strict sterile conditions throughout.

Main Applications of PRP
1. Sports Medicine and Orthopedics
Athletes and patients with musculoskeletal injuries often turn to PRP to:
- relieve knee osteoarthritis pain and improve mobility,
- speed up recovery from tendon and ligament injuries like tennis elbow or Achilles tendinopathy,
- support healing after arthroscopic or ligament reconstruction surgery.
2. Dermatology and Aesthetics
PRP has gained popularity in aesthetics and is often called the “vampire facial.” Doctors use it to:
- Rejuvenate skin by boosting collagen production, improving elasticity, and softening fine lines.
- Treat hair loss by stimulating dormant follicles and increasing hair density.
3. Dentistry and Oral Surgery
Dentists use PRP to:
- accelerate bone healing in the jaw after extractions or implants,
- reduce swelling and pain while improving soft tissue recovery.
4. Chronic Wound Care
Clinicians apply PRP to diabetic foot ulcers, venous leg ulcers, and radiation-related wounds. By improving circulation and cell growth, PRP often helps wounds that resist standard treatments.
Advantages of PRP
- Safe and autologous: Patients use their own blood, which eliminates rejection risk.
- Natural repair process: Growth factors replace or reduce the need for external drugs.
- Versatile applications: Doctors apply PRP across sports medicine, aesthetics, dentistry, wound care, and more.
- Minimally invasive: Patients usually receive treatment in an outpatient setting with a short recovery time.
Limitations and Challenges
- Variable outcomes: Patients respond differently, and studies show mixed results.
- High cost: Insurance rarely covers PRP, so patients often pay out of pocket.
- Need for multiple sessions: Conditions like hair loss usually require several treatments.
- Not a cure-all: Severe structural injuries often still require surgery.
Key Considerations
- Doctors carefully evaluate who qualifies for PRP, since patients with blood disorders, severe anemia, or infections may not be suitable.
- Patients should stop taking aspirin and other blood-thinning drugs before treatment.
- After injection, patients may feel mild soreness or swelling and should avoid intense exercise until recovery.
- Only trained professionals in sterile settings should perform PRP to ensure safety and effectiveness.
FAQs
Q1: Does PRP treatment hurt?
A: You may feel slight pain during the injection and soreness afterward, but most patients tolerate it well.
Q2: How soon will I see results?
A: Joint treatments may bring relief in a few weeks. Hair regrowth usually takes three to six months.
Q3: Can everyone get PRP?
A: No. Pregnant women, cancer patients, and people with severe blood conditions should avoid it. Always consult a doctor first.
Q4: Will one treatment be enough?
A: Most patients need a series of treatments. For hair restoration, three or more sessions are common.
Q5: How is PRP different from stem cell therapy?
A: PRP releases growth factors from platelets, while stem cell therapy uses live cells that can develop into new tissues. Doctors may combine the two in certain cases.
Summary
PRP treatment represents a powerful form of regenerative medicine. By using platelets and their natural growth factors, it activates the body’s healing process and supports recovery in many fields.
From sports medicine to aesthetics, from dentistry to wound care, PRP continues to show strong potential. Still, patients should keep realistic expectations and rely on professional guidance when choosing it. As research advances, PRP will likely take on an even greater role in clinical practice.
