PRP (platelet-rich plasma) treatment

I wanted to ask about PRP treatment and this is how it works:

A sample of the patient's blood is drawn. The blood is then processed in a centrifuge to separate the platelets from other blood components. The concentrated platelet-rich plasma is then injected into the area needing treatment. The injected PRP stimulates the body's natural healing process by releasing growth factors and other proteins that promote tissue regeneration, collagen production, and inflammation reduction.

Is this allowed? Because I have acne scars... and I don't know if its allowed or not.
