The fabric of the lingerie contains crystals that emit infra-red rays to stimulate blood flow, melting away the fat and toxins that cause cellulite, it is claimed.

Independent research has shown that 82 per cent of women who wear the underwear every day for a month see their cellulite reduced and lose inches around their stomach, hips and thighs, the department store says.

The two styles from SCALA'S "Bio-Fir Anti-Cellulite" range offered by the retailer are priced at £25 and £30 respectively, and are available in shops from Thursday.
