The Spice Girls singer allegedly spends £320 on the 90-minute spa, which includes shining a red LED light on the face, before gel mixture is spread over with gold flakes, according to The Sun.
She is said to be a regular visitor of Beverly Hills professional Dr Harold Lancer, who is also a personal doctor of Kim Kardashian and Jennifer Lopez.
The treatment reportedly does not harm any animals, with their stem cells being extracted, before getting frozen and mixed into a gel.
Dr Lancer imports the placenta from New Zealand, saying: "They have no impurities in their system."
Victoria Beckham recently revealed her plans to launch her own eponymous fashion label.
