Phương pháp PRP là gì? Ưu và nhược điểm của “cấy máu tự thân”?



Have you ever heard of Platelet Rich Plasma (PRP)? This groundbreaking new method in the field of beauty is considered a major advancement in aesthetic medicine. PRP is known to accelerate the healing process, stimulate the growth of new skin cells, and rejuvenate the skin. But what exactly is PRP? What are PRP injections? Do you really need it? Let’s find out in this article.

What is PRP?

Platelet Rich Plasma (PRP) is a method that involves injecting autologous blood rich in platelets into the body. PRP is believed to promote the formation of new blood vessels, stimulate collagen and fibrin production, and help with the regeneration and rejuvenation of the skin.

The idea behind this method is to inject PRP into damaged tissues. This process stimulates the body’s regeneration, production of new skin cells, and quick and safe healing of wounds.

Researchers believe that the high concentration of growth factors in PRP injections can stimulate the regeneration and healing of body tissues more effectively.

How does PRP work?

Platelets play crucial roles in the body. They promote blood clotting to prevent excessive bleeding and contain proteins that facilitate wound healing.

Researchers hypothesize that when high-concentration platelets are injected into inflamed or injured areas, they can accelerate the body’s natural healing response.

The Purpose of PRP

Researchers are currently exploring the use of PRP injections for the treatment of various conditions, including:

Hair Loss

Dermatologists have successfully used PRP injections to stimulate hair growth and prevent hair loss. Studies have shown that the effectiveness of PRP in treating androgenic alopecia (male pattern baldness) depends on the presence of androgen (male hormone).

Scar Treatment

PRP has a role in speeding up wound healing on the body. Its effectiveness in filling indented scars is significantly higher thanks to the autologous platelets that contain growth factors, which promote tissue regeneration.

At Grace Skincare Clinic, the combination of PRP and microneedling has successfully treated many customers’ scars.

Tendon Injuries

Tendons are thick, tough tissue bands that connect muscles and bones in the body. Their recovery time is usually slow after an injury.

Dermatologists have used PRP injections to treat chronic tendon issues, such as tennis elbow (inflammation of the tendons on the outside of the forearm) and jumper’s knee (patellar tendinitis or inflammation of the patellar tendon), providing relief and faster healing.

Acute Sports Injuries

Dermatologists have also used PRP injections to treat acute sports injuries, such as hamstring strains or knee ligament sprains.

Post-Surgical Recovery

Sometimes, dermatologists use PRP injections after surgery to aid in the recovery of torn tendons (e.g., rotator cuff tears) or ligaments (e.g., anterior cruciate ligament tears).


Dermatologists have injected PRP into the knees of individuals with osteoarthritis. A 2015 study showed that PRP injections were more effective than hyaluronic acid injections (a traditional beauty method) in treating osteoarthritis.

However, this study only involved a small group of 160 individuals, so larger studies are needed for a definitive conclusion.

It is essential to note that none of these methods have been conclusively proven to produce results. Dermatologists will consider your health condition and concerns to provide appropriate solutions.

The PRP Injection Procedure

Here is what typically happens during a PRP injection procedure:

  • Before the PRP injection, a medical professional will take a blood sample. The amount of blood depends on the area that will receive the PRP injection. For example, a study from 2014 used 20 ml of blood (a little more than a teaspoon) for PRP injections into the scalp.
  • The blood sample is then placed in a centrifuge machine. This high-speed device separates the blood into its components. The process takes about 15 minutes.
  • The separated platelet-rich plasma is prepared for injection into the targeted area.
  • Dermatologists typically use imaging techniques like ultrasound to determine the specific injection sites, such as the tendons. Afterward, the PRP injection is performed.
  • According to Emory Healthcare, this process usually takes about an hour.

Grace Skincare Clinic uses high-quality activated platelet-rich plasma (PRP) that meets FDA & CE standards, ensuring both effective and safe treatments for customers.

With activated PRP, platelets release growth factors, eliminating residual red blood cells, white blood cells, and platelets. This ensures a lower risk of skin inflammation after treatment.

PRP Technology Combined with Microneedling for Various Conditions

At Grace Skincare Clinic, dermatologists apply and perform PRP rejuvenation methods using microneedling for various conditions, including:

  • Treating acne scars
  • Skin rejuvenation for a brighter, smoother complexion
  • Improving aging issues: stimulating collagen production to improve wrinkles, sagging skin, and elasticity
  • Minimizing pore size
  • Achieving a brighter and more even skin tone
  • Treating skin damage: reducing the appearance of freckles and sunspots
  • Providing safe and effective hair loss treatments

Frequently Asked Questions about PRP

What are the possible side effects of PRP?

PRP is an autologous substance, meaning it contains substances directly taken from the patient’s body. This reduces the risk of injection reactions compared to other types of drugs, such as cortisone or hyaluronic acid.

However, since PRP involves injecting a substance into the skin, PRP technology can have side effects on the body. The potential side effects of PRP include:

  • Infection
  • Nerve damage
  • Pain at the injection site
  • Tissue damage

It’s important to discuss the potential risks of PRP with a medical professional and learn how to minimize these side effects.

Can I perform PRP at home?

Dermatologists advise that PRP rejuvenation should only be performed at reputable healthcare facilities that ensure quality and adhere to medical standards.

Attempting to perform PRP procedures at home without sufficient knowledge can harm your skin and even lead to serious consequences, such as skin inflammation, skin infection, or even blood infection.

This method is commonly practiced in many spas and beauty clinics.

However, dermatologists at Grace Skincare Clinic recommend that if you are not familiar with this beauty method, it is best to consult a dermatological hospital or reputable clinic to receive proper advice and treatment plans for your specific skin conditions.

How long does it take to recover from a PRP injection?

After a PRP injection, dermatologists may recommend that you rest the treated area. However, this recommendation is more related to the injury rather than the PRP injection itself. Most individuals can resume their daily activities after a PRP injection.

As PRP injections aim to promote tissue healing and growth stimulation, you may not notice immediate changes after the injection. However, over the course of several weeks or months, you may observe significant improvements in the treated area or increased hair growth.
