Platelet-rich plasma (PRP) therapy has become a popular option among aesthetic clinicians for rejuvenating skin and treating hair loss due to its minimally invasive nature. This cutting-edge treatment uses the body’s own healing ability to promote cell repair, collagen regrowth, and tissue regeneration. However, one of the questions that arise with this therapy is the origin of the injections.

So, where does the platelet-rich plasma used in therapy come from? PRP treatment uses autologous blood, which is drawn from the patient. The blood is then centrifuged at a high speed to obtain a platelet-rich plasma liquid that contains a high concentration of growth factors. PRP is a safe and low-risk procedure that requires only a few injections and can effectively treat a variety of cosmetic conditions.

Understanding the Contents of PRP Treatment: How PRP Injections are Prepared

Platelet-rich plasma therapy is a form of regenerative medicine that has been shown to be effective in treating acute sports injuries such as torn tendons, as well as musculoskeletal injuries and chronic pain conditions like knee arthritis. Recent innovations in cosmetic medicine have also demonstrated that PRP can improve skin aging symptoms and promote hair growth.

Unlike other cosmetic injections that use neurotoxins or fillers, PRP is made from a patient’s own blood. Platelets, which contain numerous proteins and growth factors that play a crucial role in repairing damaged cells and tissues, are an essential component of blood. When injected into the target treatment area, PRP can help the body develop new cells, which can accelerate soft tissue healing and repair.

The process for preparing PRP injections involves three primary steps:

1. Blood draw: The first step in any PRP procedure is to collect a blood sample. Using a small needle, the healthcare provider will extract a small amount of blood from the patient. The amount of blood drawn depends on the area being treated and where the serum will be injected. For instance, PRP treatment for hair loss usually requires at least 20 mL of blood.
2. Centrifugation to isolate the platelet-rich plasma: The blood sample is placed in a vial or tube and then placed in a centrifuge machine to begin the platelet separation process. The machine spins at high speeds, causing the concentrated platelets to float to the top of the plasma liquid while other blood cells are isolated at the bottom. The centrifugation process typically takes around 15 minutes to complete.
3. Preparation of PRP serum for injection: The centrifugation process produces a serum with highly concentrated platelets, much more than what is found in normal blood. The healthcare provider collects this serum in a syringe and immediately injects it into the patient.

Methods for Separating Platelet-Rich Serum from Blood

Different methods can be used by clinicians to produce a plasma sample with a high platelet count. There are various PRP kits available that use unique segregation techniques to obtain the platelet-rich plasma serum. Here are three ways to collect the PRP solution from blood:

1. Gel separator system: This process is one of the easiest ways to separate the plasma and platelets from the whole blood volume. It works by spinning the blood in a test tube that is filled with a gel substance, which captures platelets in a gel layer using osmosis, while the other blood cells remain on the other portion. However, this gel-based separator system can result in plasma with a low platelet concentration.
2. Single spin, buffy coat system: This system generates a thin layer known as the buffy coat, which contains a concentration of white blood cells and platelets. The blood sample is spun at a very fast speed to obtain this buffy coat layer, which separates the blood cells into three layers. The topmost layer contains the plasma liquid, followed by the WBCs and platelets in the middle and the separated red blood cells at the bottom. Buffy coat-based kits are said to provide a high platelet concentration for PRP injections that is at least 5 to 7 times higher than the normal platelet count.
3. Double spin, buffy coat system: Adding a second soft spin to the initial buffy coat procedure completely isolates the platelets from the red blood cells. With a single spin, there is still a considerable amount of red blood cells present in the serum. Taking it for another centrifuge will remove them entirely, leaving almost pure platelets in the plasma solution.

Factors That Can Affect Concentration Of PRP Injections 

The concentration of platelet-rich plasma (PRP) in injections can be affected by various factors, including:

1. Method of preparation: Different methods of PRP preparation, such as gel separator, single spin buffy coat, and double spin buffy coat, can yield different platelet concentrations.
2. Type of blood collection tube: The type of tube used to collect the blood sample can affect the final PRP concentration. Tubes with anticoagulants such as citrate or EDTA can reduce platelet activation and aggregation, leading to lower platelet counts.
3. Platelet count in the patient’s blood: The platelet count in the patient’s blood can influence the final concentration of PRP. Patients with higher platelet counts tend to have a higher concentration of platelets in their PRP.
4. Age and health status of the patient: Older patients and those with certain health conditions may have lower platelet counts, which can result in lower PRP concentrations.
5. Timing of injections: The timing of PRP injections can also affect the concentration of platelets. Injecting PRP too soon after preparation may result in lower platelet concentrations due to incomplete activation, while waiting too long can lead to platelet aggregation and lower concentrations as well.

It is important to note that the optimal concentration of PRP for various applications is still being researched and debated, and may vary depending on the specific condition being treated.

Why PRP Injections Are Becoming So Popular?

PRP (platelet-rich plasma) injections have become increasingly popular in recent years due to their potential to treat a wide range of medical conditions and aesthetic concerns. Here are some reasons why PRP injections are becoming so popular:

1. Non-invasive: PRP injections are considered a non-invasive treatment option as they involve injecting a patient’s own blood, which is a natural substance, back into their body. This means that there are no surgical incisions or invasive procedures required.
2. Minimal downtime: Compared to more invasive treatments, PRP injections usually require little to no downtime, meaning patients can return to their daily activities almost immediately after the procedure.
3. Versatile: PRP injections can be used to treat a variety of conditions, from sports injuries and chronic pain to cosmetic concerns such as hair loss and skin aging. This versatility makes PRP a popular treatment option for patients seeking a natural and holistic approach to their health and wellness.
4. Low risk: Since PRP injections use a patient’s own blood, there is little risk of allergic reactions or infection. This makes it a safe treatment option for many patients, including those who may not be candidates for other types of medical procedures.
5. Potential for long-lasting results: Many patients report long-lasting results from PRP injections, as the treatment stimulates the body’s natural healing processes and promotes tissue regeneration. This means that patients may not need to undergo multiple treatments or procedures to achieve their desired outcome.

Overall, PRP injections have gained popularity due to their minimally invasive nature, versatility, safety, and potential for long-lasting results.
