Cupping made headlines during the 2016 Rio Olympics, when Michaelย Phelps attributed the round, purpleย bruises on his back to the alternative medicine practiceย usedย to treat everything from muscle soreness toย arthritis and blood diseases. Now, celebrities are getting the skin-suctioning therapy on a newย part of their bodies: their faces.

Kim Kardashianย recently posted a photo onย Snapchatย of a collection of serum bottles and glass jars with balloons on top. “Face cupping facial at Nurse Jamie,” she wrote on the pic. We wanted to know: doesย cuppingย really help rejuvenate skin? And what about the bruising?! (The reality star did not share aย post-treatment selfie.)

In an interview with The Hollywood Reporter, Nurse Jamie (aka Jamie Sherrill), facialist to the stars,ย said thatย cupping uses mild suction to drain lymph nodes, getting “rid of any sign of a jowl and fight[ing] inflammation for a perfect profile or over-the-shoulder photo moment.”ย She uses the technique at Beauty Park Medical Spa, a destination forย A-listersย seekingย non-surgical skin treatments.ย Kate Beckinsdale’s aesthetician, Kat Rudu, also uses facial cupping on her celebย clients, according to The Hollywood Reporter.
