What is PRP (Platelet-Rich Plasma) Therapy?
PRP therapy is a leading regenerative treatment that uses the healing power of your own platelets to accelerate tissue repair and recovery. At USA STEM CELL, Dr. Castellanos carefully tailors each PRP injection to activate and enhance your body’s natural healing response.
This minimally invasive alternative to surgery and long-term medications delivers a concentrated dose of platelets — rich in growth factors, cytokines, and anti-inflammatory properties — directly to the targeted area.
We offer PRP therapy for patients seeking a safe, effective solution for spine pain, joint pain in the shoulders, knees, and hips, as well as select aesthetic treatments.
Healing Times
The latest studies show the increased concentrations of growth factors within platelet-rich plasma may help speed up the healing process, shortening healing times.

Versatile Applications
PRP therapy can be used for a wide range of medical and cosmetic needs. Our experienced team designs customized PRP treatments for conditions such as osteoarthritis, sports injuries, and hair loss. Platelet-rich plasma works to repair damaged tissues, restore function, and enhance overall quality of life.
Conditions We Treat
Sports Injuries
PRP therapy is a highly effective, non-surgical option for athletes and active individuals dealing with muscle, tendon, and ligament injuries. Both professional and amateur athletes are experiencing transformative results with our sports medicine treatments, which can help repair damage, reduce pain, and restore performance.
Common conditions treated include:
- Tennis elbow
- Rotator cuff tears
- Golfer’s elbow
- Chronic pain from repetitive stress injuries in the knee and shoulder
Spine
Spine
- Ankylosing spondylitis.
- Herniated disk or Ring break.
- Worn disk.
- Cervical radiculopathy (Pinched Nerve).
- Stenosis of the lumbar spine (Lumbar Spinal Stenosis
The procedure consists in implementing autologous cells from fat, marrow, placental cells and biological products such as PRP or cord derivative and exosomes inside of the infected disk. All this can be combined or implemented individually based on the size of the lesion in the MRI and the capacity of the remodeling organism (also shown in the MRI)All implants in the column require a light sedation called conscious sedation to prevent the nervous system from overreacting. It is necessary to be fasting and to have an intravenous or serum placed. You must also stop anticoagulants or anti-inflammatories for seven days.
Tendon & Injuries
- Peripheral neuropathy.
- Torn meniscus.
- Anterior Cruciate Ligament (ACL).
- Temporomandibular (TMJ).
- FIBROMYALGIA.
- Muscle strain.
- Calcaneal spur.
- Golfer’s elbow or Tennis elbow.
- Sports injuries that take a long time to heal.
- Complex Regional Pain Syndrome (CRPS).
- Trigeminal neuralgia.
- Piriformis syndrome.

Aesthetics Uses for Skin Treatments
PRP therapy has been shown in studies to visibly reduce wrinkles, smooth fine lines, diminish hollow dark circles under the eyes, and improve the appearance of acne scars. By naturally stimulating collagen production, supporting hyaluronic acid synthesis, and enhancing skin elasticity, PRP helps restore a youthful, healthy glow.
At our clinic, we offer a wide range of PRP and stem cell skin treatments designed to refresh and rejuvenate your appearance, including:
- PRP Facial & Facial Rejuvenation
- Wrinkle and fine line reduction (non-surgical facelift)
- Skin tightening and plumping
- Enhanced skin tone and texture
- Improved moisture retention
- Treatment for dermatitis and rosacea
- Acne and scar reduction
- Correction of skin hyperpigmentation
- Hair growth stimulation and hair restoration
Experience a natural, minimally invasive approach to healthier skin and hair — with results that come from your body’s own regenerative abilities.
How PRP Therapy Works at USA STEM CELL
Step 1: Draw Blood
A small amount of blood is taken from your arm — similar to a routine lab test. This provides the platelets that will be used for your treatment.
Step 2: Platelet Separation
Your blood is placed into a specialized centrifuge machine, which spins it at high speed. This process separates and concentrates the platelets, creating platelet-rich plasma (PRP) — the powerful healing component.
Step 3: PRP Injection
The PRP is carefully injected into the targeted area of concern. These concentrated platelets release natural growth factors that stimulate healing, repair damaged tissue, and reduce inflammation.

PRP Therapy FAQs
What are PRP injections?
PRP, or Platelet-Rich Plasma therapy, is a regenerative treatment that uses your body’s own blood to promote healing. Platelets are natural components in the blood that contain powerful growth factors essential for tissue repair and regeneration.
During the procedure, a small blood sample is taken and spun in a centrifuge to separate and concentrate the platelets. This platelet-rich plasma is then injected directly into the area that needs healing.
By delivering these growth factors where they’re needed most, PRP stimulates tissue repair, reduces inflammation, and accelerates recovery. It is commonly used to treat joint and tendon injuries, support hair restoration, and enhance skin rejuvenation—all with minimal downtime.
How fast does PRP treatment work?
The results and timeline of PRP (Platelet-Rich Plasma) therapy can vary depending on the condition being treated and each patient’s unique healing response.
Most patients—around 90%—notice some relief within the first week after their initial injection. However, the full benefits of PRP develop gradually over the following weeks to months, as the concentrated growth factors stimulate the body’s natural repair and regeneration processes.
For best results, an initial series of three PRP sessions is often recommended, typically spaced 4 to 6 weeks apart. This approach is especially effective for chronic or more severe conditions. Setting realistic expectations and reviewing your personalized treatment plan with your provider will help ensure the best possible outcome.
What conditions can PRP treat?
PRP therapy is a highly versatile treatment used to address a wide range of conditions. It has shown strong benefits for joint and soft tissue injuries such as osteoarthritis, lumbar disc pain, TMJ disorders, muscle tears, rotator cuff injuries, and tendon or ligament damage.
Beyond orthopedic applications, PRP is also being utilized in cosmetic medicine, hair restoration, sexual health (including ED), and even to support faster healing after surgery.
With its strong safety profile and broad range of uses, PRP continues to improve patients’ quality of life while expanding the possibilities of modern regenerative medicine.
What are the side effects of PRP?
PRP is generally considered very safe since it uses your own blood, which greatly reduces the risk of allergic reactions or complications. Most side effects are mild and temporary, such as:
- Slight soreness at the injection site
- Mild swelling, redness, or bruising
- Temporary stiffness or discomfort for a few days
These effects usually resolve on their own within a few days. Serious side effects are rare, but as with any injection, there is a small risk of infection, nerve irritation, or injury to surrounding tissue.
Because PRP relies on your body’s own healing factors, it is one of the safer regenerative treatments available. Still, it’s important to discuss your medical history with your provider to ensure PRP is the right option for you.
