A cosmetic process known as a “vampire facial” is considered to be a more affordable and less invasive option than getting a facelift, but the process can be a serious health hazard if done in unsanitary conditions, according to a new report.

That proved to be the case for three women who likely contracted HIV from receiving vampire facials at an unlicensed spa in New Mexico, making the first known cases of the virus being transmitted during a cosmetic injection procedure, according to the findings published Thursday by the Centers for Disease Control and Prevention.

During a vampire facial, a person’s blood is drawn from their arm, and then platelets are separated out and applied to the patient’s face using microneedles, according to one skin clinic. The procedure, also called platelet-rich plasma, or PRP, is touted by proponents as helping to reduce pore size and fine lines as well as rejuvenating the skin.

But multiple people with no known risk factors for HIV were likely infected with the virus through vampire facials at the since-closed facility, the CDC report said.

“This investigation is the first to associate HIV transmission with nonsterile cosmetic injection services,” it stated.
