Kim Kardashian West has been having £3,120 ''face-ironing facials''.
The 'Keeping Up with the Kardashians' star is undergoing painful Thermage laser treatments - which are also popular with stars including Demi Moore and Gwyneth Paltrow - to boost collagen levels by having radio-frequency waves delivered to the deeper layers of skin via a 'smooth wand' and is already delighted with the results.
A source told Grazia magazine: ''Kim has been having regular Thermage facials. If there's a new beauty trend, she wants to be one of the first to try it and, while it's painful, she's seen great results.''
Kim's husband Kanye West - with whom she has 14-month-old daughter North - is said to have encouraged her to have the treatments.
The source added: ''Kanye doesn't like her having invasive beauty treatments, so this is ideal.''
In the past, the 33-year-old beauty has tried Botox, vampire facials and VelaShape to beat cellulite, and has been rumoured to have had breast implants, liposuction and a butt-lift.
A source said: ''Kim isn't afraid of going to great lengths to attain her perfect look.''
