Platelet Rich Plasma (PRP) is not for everyone. As with all cosmetic procedures, however, there are certain health conditions,  that may limit its use:
Injections should be avoided in areas where infections are present or the skin is swollen – e.g. active acne, cold sores. This will reduce the risk of infection at the injection site after the treatment.
Platelet Rich Plasma (PRP) has not been tested in pregnant women, so its use would normally be not advised by practitioners if you are pregnant.
If you are breastfeeding you should not have Platelet Rich Plasma (PRP)treatment
If you have certain health conditions, such as autoimmune, blood disorders, and cancer, you should not have Platelet Rich Plasma (PRP) treatment.
