Question 317 of 433
Microneedling, radiofrequency microneedling, and “vampire facials”?
The short answer
Plain microneedling modestly improves acne scars and texture. The radiofrequency version carries more risk. The “vampire” version adds cost without clear benefit.
Microneedling creates tiny punctures that stimulate collagen. Small trials support it for scars.
Radiofrequency microneedling adds heat. In October 2025 the FDA warned of burns, scarring, fat loss, and nerve damage from these devices and advised that only trained, licensed providers perform it.
The “vampire facial” spreads your own platelet-rich plasma over needled skin. In a careful study, patients felt their skin had improved but dermatologists who did not know which side was treated could see no difference. In 2024 the CDC reported that three women were infected with HIV at an unlicensed spa offering this procedure, the first known cases of HIV transmitted by a cosmetic treatment.
