A beauty salon in Miami is offering a bizarre new treatment dubbed 'vacuum therapy' which claims to enlarge women's buttocks.

Sculpting Goddess' $60 procedure involves two 'suction cups' being attached to each buttock for 45 minutes, and claims to 'raise, enlargen and re-affirm the gluteus [sic].'

Posting before-and-after photos to its Instagram account, the salon states: 'The proof is in the pudding. You know you want to try it out.'

The non-invasive procedure, she says, leads to a permanently more pronounced posterior, because it 'mobilizes the fat.'

Tini has had the vacuum therapy performed on herself, and reports that one year on, the results have stuck around.
