Is it okay to use my husbands leftovers from his PRP injections on my face?

Thank you for your question. I would NOT recommend using this for either you OR your husband at this point as the platelets are only active for 7 minutes after being separated. The fact that they even sent you with it is concerning. In addition to this, the risk for contamination is high. Best of luck 

Hi, thank you for your question! I highly do not recommend you use your husbands PRP on yourself. This may be harmful to you.

Using someone else's blood products, even your spouse, is a terrible idea. 
Infection and reactions to others blood products can get you into a lot of trouble healthwise.

PRP is individual's concentrated platelets. It can only be used on the person it was extracted from. 

It is generally not a good idea to use PRP that is not stored professionally by the medical office. I would refrain from using it. The fact that the office did not discard the unused PRP is something to be concerned about.  Also PRP is harvested from each person for their own treatment and is not recommended to be used for another person.
